Researchers will likely gravitate to Strahan's first volume, a detailed, six-week account of European travels taken in 1751 (7/6-8/28). Alongside accounts of weather, road and travel conditions, and various social gatherings (e.g. breakfasts, dinners, teas), Strahan's entries offer glimpses into eighteenth-century English conduct, church services, universities, courts, libraries, as well as villages, towns, and cities and their inhabitants. For example, Straham describes Newcastle as a "a place of Business and Industry equal to London" (7/15) and Paisley as a "perfect hive of industrious people" (8/6). Attending a trial, he remarks upon the conduct of the participants, writing, "The court was very solemn and the lawyers were both elegant and behaved with remarkable decency" (7/22). Strahan even visits a poorhouse in Edinburgh, by which, he remarks, "the City is not only freed of all beggars, but the offspring of such are [tirelessly] snatched from Destruction, so that the Race of disorderly people are hereby extinguished" (7/30).
 
The second (1759, 1760, 1766), third (1768, 1773, 1777), and fourth volumes (1755-1761) are much less detailed but sketch his travel (and distances covered). The fourth volume, in particular, more closely resembles an account book than a journal. As he takes stock of his properties, assets, and debts, Straham records his increasingly wealth—from £ 5,000 in total assets in 1755 to £ 12,000 in 1761.

The William Strahan diary encompasses four volumes spanning 1751-1777. The first volume features the most detailed entries, whereas the second and third volumes include shorter accounts of multiple excursions and the fourth volume serves less as a journal than a summation of accounts, debts, and holdings. The first volume's accounts of mid-eighteenth-century England ought to interest researchers interested in English urban space, governance, and social conduct.

Contrary to its title, "Sigma Xi lecture tour, 1953" includes entries between 10/14-11/22/1952, shortly after his election to the American Philosophical Society. Contained in a Spiral Stenographer's Notebook (with loose pages until the 11/12 entry), this notebook provides a granular account—often down to the hour—of his travels, meetings, lectures, and seminars with specifics accounts of people, places, and universities. Notably, Stern regularly evaluates audience attendance and engagement, and names individuals with institutional affiliations. Occasionally, he judges institutional priorities. For example, of LSU he writes, "Big campus: Spanish moss and architecture. Money assigned to enlarging stadium instead of library" (10/15/1952). And, while he tends to focus on higher education, occasionally, surrounding communities permeate his observations. For example, in his LSU entry, Stern also records segregation, adding, "road past unpainted negro houses--very small, no basement" (10/15/1952).
 
A second, unbound volume from a decade later provides a detailed account of a two-week trip to the Soviet Union. Maintained between 5/13-6/2/1963, "U.S.S.R Exchange Visit" documents Stern's travels, meetings, seminars, and sightseeing. Although most of the entries are dedicated to his genetics research, Stern also notes visits to various cultural sites and landmarks, including: the Kremlin, in whose mausoleum he writes "Lenin's face yellowish as for wax with light making it glow from inside" (5/16/1963)
 
Sverdlovsk Square, which he describes as "early-19th century Versailles-like park and castle," (5/16/1963), and the Ruski Museum, in which he describes Soviet realism as "wheat factories, sturdy healthy people, statue of men [forging] sword into plough" (5/29/1963). Stern includes at least one brief account of religious practice (or lack thereof) in 1960s Soviet Union, writing: "Morning visit to the churches in the Kremlin…They are all museums but kept in the spirit of religious places. No atheistic propaganda" (5/25/1963).

Curt Stern Papers include two diaries written after his inauguration into the American Philosophical Society and move to UC Berkeley. The first documents a national lecture tour taken in the fall of 1952 and the second, from the spring of 1963, describe an exchange visit to the Soviet Union. Read in tandem, these two volumes may interest researchers investigating Stern's work in genetics and his scholarly networks, segregation and the Jim Crow South, the post-war research university, and the Soviet Union in the Cold War.

The American Philosophical Society also possesses two diaries maintained as loose pages: seven pages from an 1888 diary, also available electronically (http://diglib.amphilsoc.org/islandora/object/text:19253#page/2/mode/1up) and 24 pages related to his 1911-12 lectures in Mexico.

The Boas collections include seven diaries that Franz Boas maintained between 1883-1912. These diaries will interest German-reading researchers interested Boas's work with the Baffinland Inuit and his lecture tour in Mexico. Non-German speakers may also browse these diaries for his personal sketches. These diaries ought to interest researchers exploring Boas's career and the history of anthropology, ethnography, and linguistics.

Bache's diary provides curt but consistent accounts of the Union's military operations, particularly along the Mississippi River. Those include the Battle of Charlotte (4/25), the Battle of Baton Rouge (5/28), and the Battle of Vicksburg (6/28). Notably, Bache travels to shore on at least one occasion, furnishing first-hand accounts of the Confederate South. For example, he attends a religious service, writing, "Some of the officers went to church where they prayed for the President of the Confed. States" (5/13). Later, he describes as Natchez as a "very pretty place" (5/18). Interested researchers might consider pairing this volume with the Thomas Hewson Bache Diary, also from 1862, which provides a surgeon's perspective on the Battle of Baton Rouge.

The Alexander Dallas Bache diary offers an unusual view of Civil War battlefields from the perspective of the superintendent of the United States Coast Survey. Bache served as Captain's Clerk aboard USS Harford flagship, one of 17 Union ships that traveled up the Mississippi River to take New Orleans. With entries spanning the spring and summer of 1862 (4/14-7/13), this volume recounts naval bombardments in the early years of the war, provides textured accounts of the Confederate South, and will no doubt interest researchers who study the Civil War, U.S. military history, and the Confederate States of America.

The travel journals of Harvard professor, curator, and evolutionary biologist George Gaylord Simpson ought to be near the top research lists of scholars investigating twentieth-century history, travel, conservation, anthropology, and paleontology. Available in seven boxes of handwritten journals, typed pages, carbon copies, and countless ephemera, Simpson's travel writings provide textured insights into his life, research, intellectual, philosophical, and political positions. Over the course of six decades of journaling (1924-1984), Simpson records at least 36 distinct expeditions, traveling to every continent and documenting discoveries in extraordinary detail and literary style. (Consider the locations identified with this note representative rather than comprehensive of his diverse travels.) Noteworthy journals include: Depression-era trips to Patagonia (1931, 1934), an extended tour of Venezuela in the late-1930s (1938-39), trips to Brazil and the Amazon basin (1954-56, 1983-84), a tour to Spain under Franco (1960), expeditions in North Africa and the Middle East just before the Six Day War (1967), visits to Australia (1951, 1968), Fiji (1968), Indonesia (1975), Papua New Guinea (1976), trips to the Galapagos (1970, 1974), expeditions to the Arctic (1974) and Antarctica (1971-73), a trip to Soviet Union during the Cold War (1977), and a tour of China after its economic reforms (1980).; In his travels, Simpson's mastery of detail is matched only by his curiosity and literary flourish. For example, during his 1938-39 Venezuela tour, he discusses everything from population density (4/25/1939) and the work of Catholic missionaries with indigenous populations (1/15/1939) to the sweet coffee in Barquisimeto (9/21/1938) and his method for killing an opossum without damaging its skin (10/6/1938). At times, his reflections blur the boundaries of prose and poetry. In a collection of reminders from his time in Los Robles, he lists: "The noise they make to shoo animals--This can't be written even approximately, something like the clearing of a throat long and viciously. The sound of rain falling on canvas, on bushes, everywhere, the roar of flooding gullies, and slip and thud of landslides. The sound of pigs slashing and shearing by night outside the kitchen. The smell of fresh, heavily roasted coffee being ground…Hillsides brilliant yellow and pale green with mecutera" (12/19/1938). Researchers may anticipate discovering such redolent entries scattered throughout Simpson's journals, as suggested by Selected Quotations. Although items are not individually cataloged, scholars may choose to begin to mine this rich collection using Anne Roe Simpson's "Note on travel diaries."
 

Interested researchers would do well to consult the detailed description of Hunter's four volumes available in the Early American History Note. For the purposes of diary researchers, the first volume (1796) warrants attention for its descriptions of indigenous peoples and early settlements. For example, Hunter offers an extended account of St. Louis (9/4/1796). He also describes an Indian woman whose nose was cut off by her husband for infidelity, a passage excerpted in Selected Quotations (9/9/1796). The 1802 journal documents Hunter's trip across Pennsylvania (Berlin, Carlisle, and Shippensburg), visit to a cave in Kentucky, and discussion of salt production at Blue Lick. Finally, the last two journals (1804, 1809) include various travels in the South, including a description of expedition to the Hot Springs of Arkansas (1804-1805) as well as longitudes and latitudes that researchers might use to trace Hunter's journey. Notably, Hunter discovers Mammoth bones, which he compares to those of Charles Wilson Peale, writing, "I cannot for bear mentioning a great natural curiosity I have just seen here [sic] about 2 ½ Tons of Bones of one or two Mammoths twice as large as Peals" (5/27/1804).

George Hunter maintained four journals during expeditions into Kentucky, Illinois, Mississippi, and Louisiana between 1796-1809. Hunter records his daily affairs, observations of territories, visits to trading centers, and commentary on international rivalries and relations with various indigenous peoples, including the Delaware, Cherokee, Chickasaw, Choctaw, and Osage. With rich, narrative accounts of western travel in the early national period—including exploration of Louisiana shortly after the Louisiana Purchase—the Hunter diaries ought to interest scholars researching the American west, Native America, and U.S. empire.

The Grace E.B. Murphy Papers include two distinct sets of diaries. The first, a two-volume account of her trip to Venezuela (2/19-3/14/1952), provides detailed accounts of animals (especially birds), vegetation (including mangrove forests and mango groves), and accounts of the people, social life, and appearance of towns and cities, including Caracas. Those interested in conservation efforts might gravitate towards entries describing a visit to a jaguar hunting camp (e.g. 3/3/1952) and descriptions of the burgeoning oil industry (2/16/1952 and 3/7/1952). Entries pertaining to oil extraction are particularly noteworthy because they include on-the-ground accounts of oil wells and comparisons of U.S. foreign policy with regards to Venezuela and Iran. Researchers may find more detailed accounts in Murphy's typed notes contained in seven folders of "Vacation in Venezuela."
 
Murphy's excursion to Antarctica sprawls across four notebooks, though "No. I," which spans 1/26-2/15/1967, provides the most detailed and sequential account of her trip to Antarctica. Entries provide accounts of other travelers, social obligations, modes of transportation, scenery, wildlife (especially penguins), glaciers and icebergs, and destinations including Buenos Aires (1/26), Punta Arenas (1/28), and Antarctica (beginning 2/5). Perhaps most remarkable are Murphy's lyrical accounts of Antarctica (e.g. 2/2, 2/5, 2/6), candid reflections on her relationship with her husband, Robert (2/4, 2/8), and even her disability (1/29). (Those interested in disability studies might also reference the folders "Your Deafness is Not You," enclosed in the same box.)
 
"No. II" picks up on 2/11/1967 but continues through 3/31/1970 with some entries related to South Africa
 
while it includes several self-contained entries, most of this notebook is comprised of supplemental notes and questions. "No. III" includes still further miscellaneous notes as well as entries from the end of the Antarctic excursion, dates 2/16-21. Finally, a fourth volume, entitled "For Grace" contains accounts from 2/10, 2/15, 2/16, 2/18, and 2/19
 
however, the penmanship differs from the early notebooks and it is not immediately clear who authored these accounts. (It could very well be her husband, Robert).

Grace Murphy's diaries offer a limited but detailed account of her travels to Argentina, Antarctica, and Venezuela with her husband, Robert Cushman Murphy in six volumes chronicling the years 1952 and 1967-70. These notebooks ought to interest researchers examining mid-century conservation, disability studies (particular the deaf), excursions to Antarctica, Venezuela under military dictatorship, and the career of Robert Cushman Murphy (whose papers are also available at the American Philosophical Society).

Henry DeWolf Smyth is perhaps best known for authoring the "Smyth Report," the official government report on the development of the atomic bomb. His diaries offer a glimpse into that report, as well as his career as physicist, diplomat, instructor, policy maker, and administrator. Recorded in 37 notebooks spanning 35 years (1935-1970), the Smyth appointment books reveal his research, extensive professional networks, and wide-ranging travels through the records of meetings, travel arrangements, cocktail parties, and dinners that filled his schedule. While the first couple journals are maintained in small "Lest We Forget" notebooks (1935-1936), the bulk of the collection is available in larger "Frances Juvenile Home Calendar Club" (1936-1958) and "Engagements" books (1959-1970) packed with notes, lists, asides, and occasional newspaper clippings. Notably, he pastes newspaper clippings related to World War II at the front of contemporaneous diaries (1939-1945) and interweaves key news from the war into his own record-keeping, including the attack on Pearl Harbor and U.S. declaration of war (12/7-12/9/1941), the death of President Roosevelt (4/12/1945), and the deployment of both atomic bombs in Hiroshima and Nagasaki (8/6-8/9/1941). Although the notes are spare, nested within them are insinuations of Smyth's ascendant career. For example, one note records his appointment as Commissioner of the U.S. Atomic Energy Commission: "Pres. Truman sees H.— [Henry] offers commission house job. H. home for dinner. We decide yes" (4/18/1949). While it is unclear who authors all of the earlier entries, his wife, Mary C. Smyth, clearly maintains later "Engagements" books (1959-1970). Notably, the "Gray Board" hearings are also detailed in separate page associated with her 1954 diary. Thus, these volumes ought to interest scholars researching Smyth's role in atomic history and international diplomacy as well as those seeking to elevate figures—such as Mary C. Smyth—whose labor might otherwise remain invisible.
 

The Herbert Spencer Jennings Papers contain at least 17 volumes of diaries and various other workbooks, notebooks, and commonplace books with which researchers may supplement those volumes. Although the volumes span 1903-1945, Jennings maintains them most regularly between 1924-1945, providing detailed insights into his research, teaching, professional networks, writing and publications in the fields of microbiology, genetics, and, to a lesser degree, eugenics. For a short period (1924-27) he maintains some entries in shorthand, but returns to a long form thereafter. Integrated throughout his entries are occasional pieces of ephemera, including notes from students (e.g. 4/8/1929), business cards (11/4/1931), newspaper clippings (7/31/1933), and even the passport photos for he and his wife, Mary Louise Spencer (6/27/1935). Researchers interested in his biography, may choose to begin their research using the volume dated 3/11/1938, which contains entries as late as 1/1/1945. That volume encompasses his retirement from Johns Hopkins University (1938), the death of his first wife, Mary (also in 1938), and his remarriage to Lulu Plant Jennings (1939). Jennings' extended trips abroad, including Italy (1903-4), Japan (1931-33), and England (1933-36), may interest scholars researching twentieth-century Europe. Notably, he maintained separate notebooks with further records and ephemera related to both of the latter trips, including two notebooks related to Japanese language and two large scrapbooks related to his time at Oxford. Finally, scholars specifically interested in his career may take an interest in his sporadic notes concerning eugenics (e.g. 1/27/1933) and Charles Davenport, who also maintained an extensive set of diaries available at the APS (Mss.B.D27). For example, nested inside the diary dated 10/12/1928-7/10/1929, Jennings encloses a note addressed to a Mrs. Lutz (5/31/1929), in which he congratulates her on the twenty-fifth anniversary of an institute, which is almost certainly Davenport's Carnegie Institute (opened 6/11/1904).
 

In his detailed journal of a trip to America in the late-nineteenth century (1880), English Quaker Richard Beck offers comments on Philadelphia society and its institutions, as well as a record of his travels around America, particularly by rail. Along the way, he crosses paths with naturalist Titian Peale and artist Henry Ulke. This volume is noteworthy in two regards. First, it contains a wealth of memorabilia, including advertisements, photographs, playbills, menus, as well as Beck's own original pencil and watercolor sketches. Second, it features thoughtful and often comparative assessments of the people and places he visits. In fact, no detail can escape Beck's attentive eye. Alongside descriptions of Colorado rock formations (4/30/1880), Yosemite redwoods (6/2/1880) and the development of Salt Lake City (5/15/1880), Beck intersperses comments on American hairstyles (2/27/1880), eyeglasses (3/2/1880), libraries (4/20/1880), and that great American pastime, baseball (7/8/1880). This volume may interest scholars of postbellum material culture, late-nineteenth century Philadelphia, and the American West.
 

Early lab notes provide insights into Flexner's research in Asia. For example, an 1899-1900 diary offers a window into Manilla hospitals, travel by rickshaw in Tokyo, and observations on geisha, saki, kimonos, and Emperor in Japan. A later notebook, which purports to document a "Trip to China" in August 1915, actually features observations on the population of Honolulu, female education in Korea, and treatment of tuberculosis in Japan.
 
Later notebooks record Flexner's travels in Europe and final years as director of the Rockefeller Institute. A book misdated "January 3, 1931" provides an account of his journey to England and France to attend the Inter-Allied Scientific Conference (9/15-12/28/1918). Notably, on that trip, Flexner learns of the armistice from his waiter and wonders what the future will hold for Germany after the dissolution of Austria-Hungary (11/11/1918). Interspersed in later journals, researchers will discover Flexner's reflections on "Hitler & Jewish intellectuals" (4/12/1933) and the musings on the "German University Situation" (4/15/1933). In a notebook dated December 1934, Flexner documents a trip to Cairo (12/21/1934) and an encounter with FDR, Jr. (1/18/1935). Several notebooks document his directorship at the Rockefeller Institute between 1930-35, including the effects of the Great Depression on the Institute's budget (6/5/1932), encounters with Rockefeller family in (1931 and 1935), and his personal ambitions (1931).
 
Perhaps most surprising are a series of loosely-bound notes from 1938-1944. Those notes include a trip to England on the eve of World War II (1/1/1938-2/7/1939) as well as reflections on the outbreak and progress of the war. "England & France having exhausted every effort to influence Hitler declared war on Poland," he writes two days after Germany invades Poland, adding, "No enthusiasm on the part of any population—German, English, French—on [going late] this war as happened in 1914!" (9/3/1939). A year later, he records the German invasion of Paris, writing, "poor French, poor world civilization" (6/15/1940). Researchers interested in the history of World War II will discover that Flexner studiously records and comments upon key events, including Italy's entrance into the war (6/10/1940), FDR's declaration of a state of emergency (5/27-5/28/1941), the Japanese bombing of Pearl Harbor (12/7/1941), the U.S. declaration of war on Japan (12/8/1941), the surrender of Italy (9/4/1943), D-Day (6/6/1944), the liberation of Paris (8/23/1944), and FDR's landslide reelection to a fourth term (11/7/1944).

With 38 volumes spanning 1899-1944, the Simon Flexner Diaries (1899-1944) provide rich insights into Flexner's laboratory work, leadership at the Rockefeller Institute, study of pathology and bacteriology in the Philippines, and observations on Europe at the outbreak of World War II. Alongside his laboratory notes from Manila (1899-1900), early notebooks record medical and ethnographic observations from Japan (1900, 1915), Korea (1915), and Hawaii (1915), whereas later journals document his late-tenure as director of the Rockefeller Institute (1930-35), travels in colonial Egypt (1934), and visit to France (1918, 1931) and England (1918, 1931, 1938-39) in the years between World War I and World War II. The diaries contained in the Simon Flexner Papers ought to interest scholars researching twentieth-century medicine, philanthropy, colonialism, and war, as well as Flexner's leadership of the Rockefeller Institute and contributions to the fields of pathology and bacteriology.

A later notebook, which purports to document a "Trip to China" in August 1915, actually features observations on the population of Honolulu, female education in Korea, and treatment of tuberculosis in Japan.
 
Later notebooks record Flexner's travels in Europe and final years as director of the Rockefeller Institute. A book misdated "January 3, 1931" provides an account of his journey to England and France to attend the Inter-Allied Scientific Conference (9/15-12/28/1918). Notably, on that trip, Flexner learns of the armistice from his waiter and wonders what the future will hold for Germany after the dissolution of Austria-Hungary (11/11/1918). Interspersed in later journals, researchers will discover Flexner's reflections on "Hitler & Jewish intellectuals" (4/12/1933) and the musings on the "German University Situation" (4/15/1933). In a notebook dated December 1934, Flexner documents a trip to Cairo (12/21/1934) and an encounter with FDR, Jr. (1/18/1935). Several notebooks document his directorship at the Rockefeller Institute between 1930-35, including the effects of the Great Depression on the Institute's budget (6/5/1932), encounters with Rockefeller family in (1931 and 1935), and his personal ambitions (1931).
 
Perhaps most surprising are a series of loosely-bound notes from 1938-1944. Those notes include a trip to England on the eve of World War II (1/1/1938-2/7/1939) as well as reflections on the outbreak and progress of the war. "England & France having exhausted every effort to influence Hitler declared war on Poland," he writes two days after Germany invades Poland, adding, "No enthusiasm on the part of any population—German, English, French—on [going late] this war as happened in 1914!" (9/3/1939). A year later, he records the German invasion of Paris, writing, "poor French, poor world civilization" (6/15/1940). Researchers interested in the history of World War II will discover that Flexner studiously records and comments upon key events, including Italy's entrance into the war (6/10/1940), FDR's declaration of a state of emergency (5/27-5/28/1941), the Japanese bombing of Pearl Harbor (12/7/1941), the U.S. declaration of war on Japan (12/8/1941), the surrender of Italy (9/4/1943), D-Day (6/6/1944), the liberation of Paris (8/23/1944), and FDR's landslide reelection to a fourth term (11/7/1944).

Morley's early diaries provide intimate accounts of personal affairs, including his romantic relationships and education at Harvard University. In addition to documenting his budding relationship with Alice Williams, whom he would marry in 1908 and divorce in 1914, Morley writes at length about the planning of his first field trip to the Yucatan (1906-07). During that trip, he provides rich accounts of Havana (2/4/1907), Uxmal (2/15/1907), and his first excavation (8/19/1907).
 
Starting in 1912, his diary takes on a closer resemblance to a field notebook, with detailed accounts of his excavations in Belize, Guatemala, Honduras, El Salvador, and Mexico. Interspersed in those records are fascinating accounts of the World War I and World War II, including oblique references to Morley's espionage work. For example, on January 9, 1914 he writes of a "curious telegram warning" from Washington: "'Make no affiliations in the C.matter. This is a danger signal. Await further advices.' I cannot imagine what this can mean. Is it a warning against H.? I sent the following reply: 'Have made no affiliations whatever. Will make none. Will preserve absolute secrecy and keep free from all entanglements. My case is in your hands. Am awaiting further instructions.' Think I will hear by Monday."
 
As the war unfolded, Morley recorded its effects in both Central and South America, including President Woodrow Wilson's "destructive" policy in Mexico (2/13/1914), the geopolitical scramble for Guatemala, and the "key-stone of the arch between the Rio Grande and the canal" (12/8/1917). Later, at the outset of World War II, Morley notes Japanese encroachment on the Dutch East Indies (2/19/1941), and even the attack on Pearl Harbor, "a series of shots that literally were heard around the world" (12/29/1941).
 
In fact, war proves disruptive for Morley's work. A colleague, Dr. Moise La Fleur, is killed during a Mexican chicleros attack (5/17-19/1916), an incident from which Morley does not soon recover. Moreover his excavation of Chichen Itza is badly delayed until 4/28/1924.
 
Nevertheless, researchers interested in both the history of South America and the field of archaeology will be rewarded with meticulous descriptions of excavations conducted between the 1920s-1940s.

The 39 volumes of Sylvanus ("Vay") Griswold Morley diaries span 42 years of the first-half of the twentieth century, and provide textured accounts of Morley's personal affairs, archaeological expeditions in Central and South America, and developments of World War I and II in South America. Morley began keeping a journal while he was in school (1905) and continued maintaining it until 1946, a year before his death the year before his death (1947). Notably, all entries are typed, enabling researchers to quickly scan volumes for specific interests.

The first three volumes in the Albert C. Peale Papers are the most idiosyncratic. They include a daybook with weather observations (3/10-5/18/1864), a diary associated with a tour of Washington, D.C. during President Andrew Johnson's administration (c.1865-1869), and a lecture notebook pertaining to studies at the University of Pennsylvania. Of those early volumes, A. C. Peale's diary of his tour of Washington D.C. is perhaps most noteworthy. It recounts his travels from Philadelphia through Wilmington and Baltimore, tours of monuments and government buildings, including the U.S. Patent Office, Government Printing Office, and White House, and a handshake with President Johnson during that tour (2/7/1865).
 
The remaining six diaries (1872-1877) are devoted to various western expeditions in what is today Colorado, Wyoming, and Utah. In his first diary (5/15-7/20/1872), A. C. Peale recounts his travel by rail from Philadelphia to Omaha, from which he would conduct his western expeditions. The second volume (5/29-8/15/1873), devotes significant attention to his mineralogical work, including gathering fossils, documenting canyons and volcanic peaks, and ascending various peaks and plateaus. Notably, he references photographer William Henry Jackson, who he writes "disturbed us to take a picture." (8/8/1873). The next two diaries (8/16-10/26/1873 and 5/14/1873-7/18/1874) recount the movement of the party over the next year, most especially campsites, weather problems, and travel constraints. The latter volume also records trip to Savannah (11/20/1873) and includes some accounts in the back of the journal.
 
The final two volumes continue in much the same vein, but offer records of interactions with Bannock and Shosoni Indians. The diary dated 7/19-11/10/1874 documents A. C. Peale's expeditions along branches of the Gunnison River, during which he encounters local tribes on multiple occasions (8/29/1874 and 9/20/1874). The final diary (5/27-10/9/1877), which corresponds with trips into western Wyoming, records numerous interactions with Bannock and Shosoni. For example, A. C. Peale writes that a Shosoni woman shares news of a fight between the whites and the Sioux (6/7/1877), and he commends the English of Bannock outside a ranch near Smith Fork (6/29/1877). Not all interactions are harmonious, however. A. C. Peale also records that Bannock kill two teamsters (8/8/1877) and that one of his his party (Gibbon) loses 300 new guns in a fight (8/23/1877).

Albert C. Peale Papers contain nine volumes that might be classified as diaries. These volumes traverse the American Civil War and Reconstruction period (1864-1877) and provide a window into the exploration and conquest of what is today Colorado, Wyoming, and Utah. The great-grandson of Charles Willson Peale, Albert Charles Peale was a prominent geologist in and author of numerous books in geology, mineralogy, and paleobotany. His journals offer a glimpse into his contributions to the Ferdinand Hayden expeditions, which explored and mapped the western United States. In furnishing numerous accounts of local indigenous peoples, including the Bannock and Shosoni, these volumes may interest scholars researching Native America, western exploration, the fields of geology and mineralogy, and the history of science.

The Expedition Journals feature three travel journals bound in a single volume. The first two document William Dunbar's expedition up the Red and Ouachita Rivers to the Hot Springs of Arkansas in 1804-1805. Although few contemporary locations are named, they include numerous coordinates that researchers may use to track the journey. "Journal... to the Mouth of the Red River" furnishes particularly lush descriptions of the settlers (e.g. 10/21/1804) and indigenous peoples (11/24/1804) in the region. The second journal records technical data from the expedition, including a thermometrical log. Both journals dovetail nicely with that of traveling companion, George Hunter, also available at the APS (Mss.B.H912).; The final journal recounts an expedition to explore the geography of the Mississippi River led by Lt. Zebulon Montgomery Pike between 1805-1806. The Pike journal provides a daily account of the activities of the expedition during an early exploration into present day Minnesota. Notably, that journal includes significant attention to exchanges between settlers and local indigenous tribes (e.g. 9/3/1805, 9/10/1805, 9/24-25/1805). That volume has been printed with variations and omissions in An Account of Expeditions to the Sources of the Mississippi and through the Western Parts of Louisiana... (Philadelphia, 1810), and it was edited in Donald Jackson, ed., The Journals of Zebulon Pike: with Letters and Related Documents (Norman, Okla., 1966). Bound together, the Dunbar and Pike volumes ought to interest a range of scholars researching U.S. exploration and Native America in the early national period.
 

The first diary and second diaries, 1893-1 and 1893-2, dovetail, though, the second diary, 1893-2, is dedicated to Shull's "favorite subjects of study" (botany, natural philosophy, chemistry, agriculture), and spans from 2/19/1893 – 2/10/1895. The 1895 diary spans the year, whereas the 1897 diary ends on 9/26/1897. While the notebook entitled "Notes on European Trip of Geo. H. Shull" is supposed to span from August 1907 to December 1908, it actually concludes on September 25. The first four diaries feature detailed accounts of the weather, Shull's personal life (namely visitors, friends, and family), chores (e.g. cutting firewood, fixing fences, ploughing snow, farming, cleaning stable, cutting corn, and pickling grapes), studies (agriculture, physics, natural philosophy, botany, chemistry, and optics), reading and writing, travels (including a zoo, musical, circus, lectures, and even a funicular on 9/8/1895), and his early public-school teaching.
 
1893-1 includes extensive accounts of and assessments of his reading (such as his critique of Vanity Fair on 1/7), attendance of a friend's funeral (2/8), writings and editorship of Ingleside Magazine (1/2, 2/1), hearing difficulties (8/6 and 12/17), and even a friend's trip the 1893 World's Fair (10/8). Most notably, shortly after Shull begins teaching (10/3) he shifts towards less frequent diary entries. Shull encloses various ephemera, including his own sketches of insects, in the final pages of this diary.
 
1893-2, which purports to provide "research, failures, & everyday account of events of my life which has any bearing upon my favorite subjects of study," particularly botany. On 3/15/93, in fact, Shull confesses to having caught "grafting fever." The diary jumps from 9/18/93 to 10/20/94, upon which Shull notes the "complete cessation from scientific activity during the period of 8 ½ months following 10/3/1893 while I was teaching my first term of public school."
 
The 1895 and 1897 diaries reveal Shull's growing Christianity: he opens both diaries with Psalms and speaks regularly about his evolving faith (2/17/1895, 6/2/1895, and 1/17/1897). On several occasions, he even revisits and quotes from early entries (1/17/1897 and 7/18/1897). Shull's study of phrenology and physiognomy surfaces throughout both notebooks, including in accounts of religious practitioners (6/2/1895), students (1/10/1897), and colleagues (3/7/1897). His heterogeneous political views include support for women's suffrage (1/6/1895) and women's rights (6/18/1895), attendance of the Republican primaries (3/17/95), his own local advocacy for a temperance petition (3/14/1897), and some sympathies for Social Darwinism, particularly with regards to immigration (2/21/1897) and education (3/7/1897). The 1897 diary concludes shortly after Shull began his studies at Antioch College.
 
In a notebook pertaining to his 1908 "European Trip," Shull provides a detailed account of his steamship journey from New York City to London (8/15-8/25/1908) with attention to sights (e.g. passing the Statue of Liberty and Ellis Island) and the social life of the ship (namely card-playing, concerts, dinners, and walks). Upon arrival in London, Shull and his party visit a range of historical sites in London, Wales, Ireland, France, and Belgium. He dedicates his most rigorous accounts, however to the various botanical gardens and methods of plant cross-breeding and grafting. This diary concludes in Ghent, bound for Berlin, and includes a printed, 12-page "Americanization" pamphlet (dated 1919), for which Will Fenton developed an online exhibit: https://diglib.amphilsoc.org/labs/americanization/

The George Harrison Shull Papers include five diaries spanning 1893-1895 and 1908. Most of these notebooks reflect Shull's early education and nascent teaching career until his enrollment in Antioch College, whereas his 1908 notes on his European trip reflect his growing interest in botany and plant breeding. The Shull diaries will interest researchers investigating those fields as well as those considering common schools and late-nineteenth-century pedagogy, postbellum politics (especially temperance and women's suffrage movements), as well as social Darwinism, phrenology, and physiognomy.

A similar printed version of the journal, edited by Anthony F.C. Wallace, was published in Pennsylvania History in 1952.

In a journal documenting his residence with the Seneca Nation in New York, Pennsylvania Quaker Halliday Jackson offers a detailed, daily account of his missionary life, travels, and Seneca customs at the turn of the nineteenth century (1798-99). Jackson offers numerous accounts of land, cultivation, and development, including early accounts of Pittsburg (p.8-9), a Seneca settlement (19), and Niagara Falls (163-64). Native American studies scholars may gravitate to the volume's descriptions of Seneca food preparation (17), marriage (148-9), alcohol consumption (14, 124-125), land deeds (53-54, 75), Quaker diplomacy (23-24, 32-33), and increasingly strained relations with backcountry settlers (126, 131-133, 146-47, 178-79), many of which are voiced by the Seneca themselves and transcribed by Jackson at council meetings. This volume also features entries that will interest scholars researching the early national period, including the Bank of the United States (75), the yellow fever epidemic (74, 114-15), and the death of George Washington (176).

In contrast to many other scientists, Donaldson captures many world events in his journal. Entries include an on-the-ground account of the 1893 World's Fair (5/13-5/27/1893) and news pertaining to the Great Baltimore Fire (2/7/1904), Russo-Japanese War (2/8/1904), and World War I. Donaldson studiously records the spread of war in Europe (7/31/1914), the increasing likelihood of U.S. involvement (2/4/1917), and false reports of peace. Several days before the Armistice, he writes, "Peace was reported here about 1 pm. The town went wild & remained wild most of the night. Report was a hoax" (11/7/1918). Donaldson also proves an active observer of and participant in U.S. politics. For example, in addition to recording the election of President Wilson (11/5/1912) and death of President Harding (8/2/1923), he writes that he travels to Harrisburg to lobby against an "anti-vivisection bill" (4/25/1907) and attends a "League of Nations dinner" (1/15/1932).
 
Perhaps most surprising is how personal affairs infiltrate the Donaldson diaries. Sometimes such asides are amusing
 
for example, in one entry he writes that he was "attacked by goose without cause" (3/31/1917). Elsewhere, they're more serious and evocative. Shortly after Donaldson writes that his first wife, Julia, is "diagnosed melancholia" and put on an "opium treatment" (9/13/1904), he records her suicide: "our dear Julia was found dead by her own hand at 7 o'clock this morning. She was still warm when found. It is desolation—the saddest of days" (11/10/1904). Several years later, he notes his engagement to Emma Brock (3/1/1907) and, still later, the birth of a son Harry, (3/16/1920). In the 1930s, his health appears to deteriorate: Donaldson begins tracking weight fluctuations on 7/13/1931 and undergoes a metabolism test on 10/17/1934. His last entry, written in third-person in a different hand, appears to have been maintained by someone else, possibly Emma. The diary concludes, "The end at 2 a.m." (1/23/1938).

Contained in 49 volumes, the Herbert Donaldson diaries traverse 1890-1938 and provide glimpses of his neurological work at the University of Chicago and the Wistar Institute in Philadelphia, meetings with leading scientists--including Boas and Davenport--European and American travels, recreational activities, personal affairs, and leadership at the National Academy of the Sciences, the American Neurological Association, the Physiological Society, the Lenape Club, the Rush Society, as well as the American Philosophical Society, where he was elected a member in 1906 and vice president in 1935. The Donaldson diaries may interest researchers exploring the history of mental health, American Philosophical Society membership, twentieth-century U.S. politics, the 1893 World's Fair, and World War I.

Hiltzheimer provides a detailed and textured account of the young republic through scrupulous attention to the Constitutional Convention, election and reelection of George Washington, the Whiskey Rebellion, the Wyoming Valley incident, and the ascension of John Adams. Thanks to his career in Philadelphia politics (elected as a representative of the city in the Assembly in 1786), he furnishes first-hand accounts of George Washington, the funerals of Benjamin Franklin and David Rittenhouse, and numerous entries devoted to Pennsylvania luminaries including John and Clement Biddle, Joseph Morris, Levi Hollingsworth, Henry Drinker, and Timothy Matlack.
 
Hiltzheimer's journal also records family and personal details, including plague of locusts in 1766 and 1783, a great fire in 1794, and the death of his wife (3/11/1790) and loss of both his son and daughter to Yellow Fever (11/28/1793 and 12/29/1794 respectively). Indeed, his account of the Yellow Fever epidemic in Philadelphia is particularly exhaustive, with daily records of burials between 9/19-12/31/1793, as well as further accounts during the 1797 crisis, during which he ultimately contracted the disease that led to his death in September 1798.

The Jacob Hiltzheimer Diary spans 28 volumes and offers insight into the social life and customs of Philadelphia between the late colonial period to the early republic (1765-1798). Hiltzheimer describes a wide range of events, such as sleigh riding to ice skating to attending a large celebration of King George's Birthday on the banks of the Schuylkill with over 380 Philadelphians (before Independence). During the imperial crisis, Hiltzheimer's observations provide an interesting perspective on the events happening within the city, including the repeal of the Stamp Act, French troop movements, Cornwallis's surrender, and ensuing mob violence against suspected loyalists (e.g. 10/24/1781).

The John Slater Papers include abstracts from his diaries, available as loose, mostly typed pages, which traverse his consequential career in physics (1900-1975). These abstracts trace Slater's doctoral study at Harvard (1923) and postgraduate work at Cambridge University, appointment at MIT (1930), work at the Laboratory for Nuclear Science during World War II, and late-career at the University of Florida (after his retirement from MIT in 1966). His diaries contain notes about a trip to Japan (including Hiroshima and Nagasaki) in the fall 1953, meetings with defense contractors (such as Lockheed Martin) throughout the 1950s and 1960s, a sighting of Sputnik (7/20/1958), notes about an "NSF proposal for computing center" (4/30/1965), associations with and publications of APS members (7/7/1951, 7/7/1972), and Slater's own personal affairs, as excerpted in Selected Quotations. As such, these abstracts may interest scholars researching John Clark Slater's career in the field of physics, biochemistry, atomic history, and the history of science more broadly, as well as those considering World War II and military contractors in the Cold War period, the space race, the history of computing, and the institutional history of the American Philosophical Society.; To supplement these diary abstracts, researchers might choose to expand their exploration of the Slater Papers, which also contain 133 research notebooks (1944-1976), a lengthy series of folders, containing lectures, scientific notes, drafts of manuscripts and papers, correspondence from his collaboration with the Los Alamos Labs (1966-1970), and correspondence relating to the National Academy of Science.
 

Warner's diaries provide an intimate record of his far-flung travels. Alongside visits to zoological and mineralogical collections, Warner patronizes numerous places of worship, for which he often provides sketches of murals and architectural features. (His most impressive color illustrations begin around March 1863). Notably, he visits a Jewish synagogue in the Netherlands (10/13/1862) and a mosque in the Middle East (3/31/1865). He copies verses from a tombstone (9/8/1862), and when he tours the Egyptian pyramids, he records hieroglyphics (4/26/1865). He encloses descriptions of natural scenes—e.g. the Wetterhorn (8/31/1862) and Rhone Glacier (9/4/1862)—and also urban spaces, including a locomotive works in Amsterdam (1/26/1863), a foundry in Greenock (1/30/1863), a prison in York (4/7/1863), a gypsy settlement in Romania (6/13/1865), and even an early account of the Grand Kremlin Palace (8/2/1868).
 
Throughout those travels, Warner recollects his native Pennsylvania to draw evocative geographic and social comparisons. For example, he equates a town outside Belgrade to Burlington on the Delaware (6/9/1865). Upon meeting a foreman at machine shop, he compares the conditions of the poor in America and Germany (8/25/1862). Of particular note, he compares the governor of Nazareth to a "Philadelphia negro" (4/15/1865).
 
At various points in his travels, Warner is compelled to confront U.S. domestic affairs, most especially the Civil War. For example, traveling by rail in Germany in late-1865, he writes, "Met in the [train] car Mr. Joseph Kommer, Lincoln Logan Co., Illinois, a few months back to Germany, now on his way home via Hamburg. He had served in the Northern Army
 
related many things respecting the war and was a good union man" (11/8/1865). Several years later, he visits a castle where he notes a "revolver presented to the King by President Lincoln" (7/9/1868). Although Warner rarely discusses politics directly, he registers his own political activities and sympathies. For example, he attends a "Peace Society" (5/19/1863), a "temperance tea" (9/15/1863), and a lecture on "dwellings for workingmen" (1/6/1866). He records at least one conversation about U.S. nativist movements, particularly the Astor Place Riots, writing, "Met an Irishman who had been in the U.S. some years ago. He doubted whether the Irish, in New York had been incited—as a clan, especially—to take part in the late New York riots, and on account of jealousy of the blacks as competitors for work—he was further opposed to Mr. Lincoln's emancipation edict" (8/18/1863). In another prescient entry, he records an exchange with a Polish miller about poll taxes. "A miller spoke to me, among other subjects, of Poland," Warner writes. "He said Austria and Prussia assist to subjugate Poland, because 'they are all tyrants together.' Of our country, he said there would soon be poll tax" (9/14/1864).
 
When it comes to the topic of slavery, Warner reveals abolitionist sympathies via ephemera. He encloses a newspaper clipping from "Aborigine Protection Society," after which he remarks on the emigration of freed slaves to Liberia (5/20/1863), and encloses another clipping entitled "Negro Emancipation" (6/17/1863).
 
Scholars of nineteenth century material culture will be richly rewarded by the diaries. Alongside hand-drawn maps of buildings, cities, and architectural features, Warner encloses numerous newspaper clippings (e.g. (1/10/1863), engravings (9/27/1864), advertisements (7/9/1865), and theatrical programs (10/6/1865). While the majority of those materials are in English, some ephemera—and Warner's own entries—are in German, French, or Italian.

With 55 volumes spanning 7/8/1862-11/23/1872, the John Warner diaries provide a detailed account of his time abroad (1862-1868) and travels throughout Europe. Although many entries are devoted to talks and lectures (mostly pertaining to zoology), Warner proves also a studious observer of people, cultures, and cultural and religious institutions, which he records through numerous sketches and ephemera. In fact, these volumes present a wealth of research opportunities for scholars of material culture, thanks to Warner's curation of nineteenth-century newspaper clippings, advertisements, programs, and personal illustrations.
