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).
 

The Arthur J. Cain Papers include one diary that coincides with his appointment as Derby Professor of Zoology at the University of Liverpool (1968). (However, there does not appear to be explicit mention of that appointment.) Although the volume is sparsely populated, it documents his university appointments, including individual meetings, lectures, seminars, exams, and at least one note pertaining to a television appearance (2/19/1968). Notably, Cain includes a letter from his secretary E.R. Shummin, written on University of Manchester letterhead (dated 10/23/1968).
 

The vast majority of the 33 volumes listed as "diaries" in the Raymond Pearl Papers might be better described as common-place books, though the collection includes at least six unbound volumes that might be accurately classified as diaries. Most of these entries pertain to various recreational European trips taken between 1905-1928. The 1905 diary includes numerous accounts of sightseeing in London, including visits to Kew Gardens (9/28), the Tower of London (9/30), and a theater, which Pearl compares to that of the United States (10/18). Pearl uses the next two journals, from 1916 and 1917 respectively, as field notebooks with miscellaneous accounts. These volumes will likely most interest scholars researching his biography and contributions to biology. A journal from 1918 includes a mix of typed and handwritten entries documenting a trip to Europe by steamship. Finally, the last two volumes might very well have been co-authored by both Raymond and Maud Dewitt Pearl. The first, a loosely bound journal bearing the dates "1924, 1927" appears to have been maintained by both Pearls. The second, dated 1928, appears to have been kept by Maud, especially given all of the third-person references to Raymond Pearl ("R.P."). Both "1924, 1927" and "1928" recount travels in England, France, and, to a lesser extent, Germany. These diaries, while quite limited in nature, may interest scholars researching Europe in the early-twentieth century, biology, and the history of science more broadly.
 

Edmund Beecher Wilson maintained a private journal than traverses much his tenure at Columbia University (12/5/1903-5/24/1928). Wilson includes frank assessments of undergraduate and graduate students, many of whom would become leaders in the fields of biology, genetics, and zoology. For example, he writes of Rebecca Lancefield—who would become a leading microbiologist—"good on the whole, faulty in spots" (5/26/1917). Other prominent graduate students include A. Franklin Shull, Jack Schultz, Hermann Muller, Calvin Bridges, Alfred Sturtevant, and Curt Stern (for whom APS possesses two diaries). Researchers interested in the history of science, education, and the research university will find this volume particularly useful.
 

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 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."
 

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.

Russian-readers will be richly rewarded, given that Dobzhansky modulates entries between Russian and English. In some entries, he self-consciously reflects on the language he opts to use. For example, on February 16, 1952, he imagines his child (Sophie) as the audience of his entries: "I am switching to English, in order that my child would find it easier to accompany her father's experiences, is she wants to accompany them."
 
Even in diaries recorded predominantly in Russian, Dobzhansky encloses numerous ephemera—business cards, letters, hand-drawn sketches, recognitions/awards, medical test results, newspaper clippings, and more—accessible to English-speakers. In many of his diaries from the 1950s and 1960s, typed letters provide some insights into his thoughts on health, mortality, and faith (e.g. 2/16/1952, 5/16/1957, 7/16/1968, 10/13/1969)
 
(strained) relations with his children (e.g. 5/16/1957, 10/28/1968, 12/31/1968)
 
and career (3/25/1970
 
6/30/1970, 1/25/1975).
 
Dobzhansky traveled widely, providing particularly detailed accounts of South America and the American West. While English entries largely abstains from discussing politics, he does occasionally discuss Brazilian politics (e.g. 9/7/1954, 10/16/1955), and the election of Richard Nixon, about whom he is consistently critical (e.g. 11/6/1970, 12/31/1973, 8/8/1974).
 
Throughout his four decades of journal-writing, Dobzhansky expresses one consistent concern: his desire to continue doing useful work. Marking his final birthday, he writes, "So, I have lived ¾ of a century. Today begins the last quarter, or rather past thereof…Oh God, give me power to finish my life serving you by doing my life work in science! In 75 years I have not yet exhausted either my interest or, I hope, my ability" (1/25/1975).

The Dobzhansky Papers feature 47 volumes spanning 1934-1975. (The boxes in which they are enclosed also include other notebooks and workbooks without sequential entries.) These diaries ought to interest researchers studying genetics and evolutionary biology, early-twentieth-century travel expeditions (particularly into the Amazon), the creationist debate (especially in textbooks and public schools), the post-war university (Columbia University, in particular), South American politics, and Dobzhansky's biography.

Davenport employed a host of different types of notebooks to record entries. Those include: Standard Diary, A Line a Day, Red Star Diary, Nassau Diary, Loesen Engagement Book, Daily Reminder, Vaughan's, New Census, Marquette, and various loosely bound notebooks. While he records weather conditions (often with temperatures), meetings, and accounts throughout those records, his earliest accounts proffer his most personal and narrative entries.
 
Between 1878-84, Davenport writes regularly about his religious upbringing, studies, work at the Polytechnic Institute, and political observations. Religion features prominently in Davenport's youth: In addition to regularly attending church and Sunday School, he records notes and thoughts about particular readings and sermons (consider for example 1/6/1878, 1/29/1882, and 2/16/1882). In a 1/22/1882 entry, he even notes the visit of a Mormon woman from Utah, which he later marks as a "principal personal event."
 
Alongside notes about subjects related to studies, Davenport records household chores (7/16/1881), recreational activities (walks, rides, croquet), trips (e.g. a summer visit to the New Hampshire White Mountains in 1884), cultural excursions (the American Museum of Natural History on 1/6/1879), personal readings (1/3/1881), and some of the first evidence of his interest in surveying (illustrations of a chapel hall, 1/2/1880). The young Davenport also demonstrated an unusual curiosity in current affairs and politics. For example, his first journal includes an enthusiastic account of election day (11/5-11/6/1878), and his 1881 diary features several entries dedicated to assassination of President James Garfield and ascension of Chester A. Arthur (9/26-9/30/1881). These early diaries are also some of Davenport's most playful: he self-consciously reflects on diary-writing (2/6-2/7/1878, 1878 memoranda, 1880 front matter, and 9/6/1880) and intersperses doodles to commemorate holidays (12/311878 and 2/22/1879, 5/30/1879, 6/1/1879).
 
Subsequent diaries are less narrative in nature, but illuminating their own right. Davenport maintains notebooks on subject area interests, including a journal entitled "Ornithology 1885" which includes migration charts from the American Ornithologists' Union," notebooks dedicated to topology, mineralogy, budding and regeneration, and research on the human brain (1885-1892), and various notebooks dedicated to the study of human inheritance. As Davenport's career begins to take off around the fin de siecle, he includes more notes related to lectures, seminars, student meetings, dinners, and lab work. His marriage to Gertrude Crotty surfaces in the five-year diary spanning 1899-1905 via birthday reminders (2/28/1899), city outings (9/11/1900), and notes related to their child, Janet (1/2/1899).
 
Researchers will find that Davenport's early-twentieth century diaries provide insights into his burgeoning career in genetics. In addition to notebooks pertaining to expeditions to the Biloxi, Mississippi (March 1901), Europe (September-October 1902 and 1909-10), and Mt. Washington (August 1908), a 1903 notebook features notes on "Topics of Inheritance" and allusions to work on a laboratory—almost certainly his Carnegie-funded lab in Cold Spring Harbor. Nevertheless, many of his entries could easily be confused with those of a farmer: Davenport records notes to purchase chicken feed, coal, grain, and rat poison, and a 1909-10 diary features numerous and meticulous illustrations of fish (October 1909 – March 1910). Concurrently, Davenport notes numerous meetings with leaders in genetics, botany, and zoology, including George Harrison Shull, Herbert Spencer Jennings, Edward Bagnall Poulton, Albert Francis Blakeslee, and Edmund Beecher Wilson. Perhaps most significantly, beginning around 1911, Davenport starts to reference Mary Harriman, who would later fund his work in eugenics.
 
Eugenics surface most directly in Davenport's diaries maintained throughout the 1910s and 1920s. Alongside regular visits to the "Harriman House," Davenport notes the opening of his laboratory ("Bio Lab Opens," 6/26/1912) and his increasing commitments to the field of eugenics. That includes notes on "Dwarfs of Lamar Lamar" (11/14/1911), reminders of "families to study (e.g. "chemists," "artists," "statesmen," "vocalists," and "naval" in his 1913 memoranda), and an account of "negative" and "positive eugenics" (January 1920). One notebook (dated "February 12") is less a diary than a set of eugenics lecture notes, including a "Field worker's guide" that describes the consequences of segregation, limitations of the law of heredity, and pages allocated for recording hair color, skin color, stature, mental activity, feeble-mindedness (e.g. pauperism, crime, insanity, criminality).
 
Between 1914-1930, Davenport makes numerous trips to Europe to study eugenics (including (1914, 1922, and 1929). His 1914 trip is explicitly labeled "Eugenics in Holland" (10/22). A series of loose, typed pages entitled "Diary of Trip to Europe, September 13 to October 31, 1922," includes notes on a lecture entitled "Das Mutations Problem" in Vienna (9/25) and his participation in the Second Commission of Eugenics through which he "Voted to admit Germany and all other, properly qualified countries to the Commission" (10/9). Perhaps most remarkably, at the end of that trip, Davenport records a meeting with Charles Darwin's son, Leonard: "At Lewes was met by Darwin and taken to his home in Sussex. Private conference on eugenical matters" (10/20).
 
That engagement carries home, where, in a 1930 diary, he includes a series of relevant newspaper clippings: "Racial related to a Racial Integrity Bill Signed" in Richmond, Virginia (3/14), "Extols African Marriage" (3/4), "Senate Refuses to Shelve Harris Quota Bill: Senate Again Rejects Motion by Glass aimed at Salvaging National origins Clause" (4/24), and "Dr. Adler Closes Psychology Clinic: Noted Viennese Scientist Declared Target of Medical Center Critics" (5/31). In some loose pages associated with that diary, Davenport compares a colleague (simply identified as "Gordon") to the Croatian-American geneticist Milislav Demerec: While Davenport finds Gordon "industrious and fertile in ideas," he adds that he is "not so brilliant as Demerec" (6/3).
 
Davenport's remaining diaries (1931-1944) mostly focus on various trips, with occasional mentions of the outbreak of World War II. The early-1930s feature a series of notebooks dedicated to travel in the Americas, including a "Western Trip" and "Trip to the West by Automobile" (which collectively span July-October 1931), as well as trips to Bermuda, Mexico, and Nova Scotia. The Nova Scotia trip is noteworthy because Davenport explicitly notes an encounter with Russian-American geneticist Theodosius Dobzhansky. In his late-1930s journals, World War II surfaces, if only briefly. In a diary spanning 1937-39, Davenport notes Germany's seizure of Poland (9/1/1939) and Great Britain's subsequent declaration of war (9/3/1939). Curiously, he also alludes to a "Cox: Atomic Nuclear" in multiple entries of June and July in his 1940 diary.
 
Finally, the Davenport diaries are noteworthy for their idiosyncrasies: these include at least one volume authored by his wife, and the eclectic range of ephemera include inside and alongside the diaries. In a volume signed "G.L. Davenport"—and bearing numerous allusions to "Charles and Charlie throughout—Gertrude Davenport records a series of entries between 4/1/1905 to 3/16/1913. Of particular interest is her protest of race track gambling (4/19/1908 and 4/23/1908) and the dedication to Carnegie Lab, with a note of an encounter with Andrew Carnegie, who "disappointed the department by not adding to the endowment" (1/3/1910). Alongside accounts of various farm and house work (mending garments, cleaning, and, unusual for a homemaker, making concrete blocks), this diary also notes Gertrude's reading, namely Harper's Monthly and the Century.
 
Across the series 95 diaries, Davenport includes a host of rich and sometimes peculiar ephemera: a letter, dated March 20, 1901 enclosed in an 1889 notebook, an image of Robert E. Lee (7/13/1905), a doodle of a family crest (3/17/1910), pamphlets related to ornithology (1920) and major snowstorm (2/2/1930), membership cards for the Arts Center of New York (1925) and the American Museum of Natural History (1943), Davenport's 1922 and 1925 passports, programs for a meeting of the Eugenics Research Association (6/3/1930) and a symposium on "Theory and Development" at Davenport's home (3/21/1930), train tickets to Washington (9/5/1918 and 7/9/1919), the ferry service between Staten Island and Brooklyn (5/3/1925), and the Long Island Railroad schedule (1927), receipts, deposit slips, and scraps of paper labeled everything from "OBESITY" (8/19/1915) to "Committee on Ways and Means" (1917), and even wooden toothpicks, which Davenport appeared to have used as bookmarks (9/5/1918, 10/31/1918, 3/12/1933, and 5/7/1933).
 
Although Davenport rarely uses his diaries for reflection, his enclosure of ancillary materials reveals his personal networks and popular reading. Throughout the diaries, scholars will discover business and calling cards for William Cohill (1902), Edith Reeves (1911), "Brinkerhoff" (1911), Sidney Ball (1914), "Antipodes" (1914), George Laible (1915), H. Lundborg (1923), Charles Herrman (1925), E.J. Lidbetter (1927), Gebruder Dippe (1930), H.J. Parsen (1933), and Ji-Yen Rikamaru (1937). Davenport also regularly encloses snippets from newspapers, including a piece Russian mogul named M. Rachatnikoff who sought "the improvement of the human race" (12/9/1906), Mary Harriman's purchase of land and sheep (9/25/1911), op-eds on immigration policy (9/9/1915) and access to birth control (1920), an obituary for Dwight Comstock (9/16/1932), and reports of Nassau County budget cuts (11/9/1942).

The Charles Benedict Davenport Papers include 95 diaries—and numerous ancillary materials—spanning 66 years (1878-1944). In fact, the collection traverses Davenport's formative years and adult life, beginning with student notebooks that he maintained at the age of 12 to a five-year diary that culminates with an entry recorded less than two weeks before his death (dated 2/5/1944). Davenport's diaries contain a wealth of material valuable to researchers investigating his personal life, scientific research—especially the field of Eugenics—religion (Congregationalism), politics, and World War II. At least one diary, which spans 4/1/1905 to 3/16/1913, appears to have been maintained by his wife, Gertrude.
 
Davenport employed a host of different types of notebooks to record entries. Those include: Standard Diary, A Line a Day, Red Star Diary, Nassau Diary, Loesen Engagement Book, Daily Reminder, Vaughan's, New Census, Marquette, and various loosely bound notebooks. While he records weather conditions (often with temperatures), meetings, and accounts throughout those records, his earliest accounts proffer his most personal and narrative entries.
 
Between 1878-84, Davenport writes regularly about his religious upbringing, studies, work at the Polytechnic Institute, and political observations. Religion features prominently in Davenport's youth: In addition to regularly attending church and Sunday School, he records notes and thoughts about particular readings and sermons (consider for example 1/6/1878, 1/29/1882, and 2/16/1882). In a 1/22/1882 entry, he even notes the visit of a Mormon woman from Utah, which he later marks as a "principal personal event."
 
Alongside notes about subjects related to studies, Davenport records household chores (7/16/1881), recreational activities (walks, rides, croquet), trips (e.g. a summer visit to the New Hampshire White Mountains in 1884), cultural excursions (the American Museum of Natural History on 1/6/1879), personal readings (1/3/1881), and some of the first evidence of his interest in surveying (illustrations of a chapel hall, 1/2/1880). The young Davenport also demonstrated an unusual curiosity in current affairs and politics. For example, his first journal includes an enthusiastic account of election day (11/5-11/6/1878), and his 1881 diary features several entries dedicated to assassination of President James Garfield and ascension of Chester A. Arthur (9/26-9/30/1881). These early diaries are also some of Davenport's most playful: he self-consciously reflects on diary-writing (2/6-2/7/1878, 1878 memoranda, 1880 front matter, and 9/6/1880) and intersperses doodles to commemorate holidays (12/311878 and 2/22/1879, 5/30/1879, 6/1/1879).
 
Subsequent diaries are less narrative in nature, but illuminating their own right. Davenport maintains notebooks on subject area interests, including a journal entitled "Ornithology 1885" which includes migration charts from the American Ornithologists' Union," notebooks dedicated to topology, mineralogy, budding and regeneration, and research on the human brain (1885-1892), and various notebooks dedicated to the study of human inheritance. As Davenport's career begins to take off around the fin de siecle, he includes more notes related to lectures, seminars, student meetings, dinners, and lab work. His marriage to Gertrude Crotty surfaces in the five-year diary spanning 1899-1905 via birthday reminders (2/28/1899), city outings (9/11/1900), and notes related to their child, Janet (1/2/1899).
 
Researchers will find that Davenport's early-twentieth century diaries provide insights into his burgeoning career in genetics. In addition to notebooks pertaining to expeditions to the Biloxi, Mississippi (March 1901), Europe (September-October 1902 and 1909-10), and Mt. Washington (August 1908), a 1903 notebook features notes on "Topics of Inheritance" and allusions to work on a laboratory—almost certainly his Carnegie-funded lab in Cold Spring Harbor. Nevertheless, many of his entries could easily be confused with those of a farmer: Davenport records notes to purchase chicken feed, coal, grain, and rat poison, and a 1909-10 diary features numerous and meticulous illustrations of fish (October 1909 – March 1910). Concurrently, Davenport notes numerous meetings with leaders in genetics, botany, and zoology, including George Harrison Shull, Herbert Spencer Jennings, Edward Bagnall Poulton, Albert Francis Blakeslee, and Edmund Beecher Wilson. Perhaps most significantly, beginning around 1911, Davenport starts to reference Mary Harriman, who would later fund his work in eugenics.
 
Eugenics surface most directly in Davenport's diaries maintained throughout the 1910s and 1920s. Alongside regular visits to the "Harriman House," Davenport notes the opening of his laboratory ("Bio Lab Opens," 6/26/1912) and his increasing commitments to the field of eugenics. That includes notes on "Dwarfs of Lamar Lamar" (11/14/1911), reminders of "families to study (e.g. "chemists," "artists," "statesmen," "vocalists," and "naval" in his 1913 memoranda), and an account of "negative" and "positive eugenics" (January 1920). One notebook (dated "February 12") is less a diary than a set of eugenics lecture notes, including a "Field worker's guide" that describes the consequences of segregation, limitations of the law of heredity, and pages allocated for recording hair color, skin color, stature, mental activity, feeble-mindedness (e.g. pauperism, crime, insanity, criminality).
 
Between 1914-1930, Davenport makes numerous trips to Europe to study eugenics (including (1914, 1922, and 1929). His 1914 trip is explicitly labeled "Eugenics in Holland" (10/22). A series of loose, typed pages entitled "Diary of Trip to Europe, September 13 to October 31, 1922," includes notes on a lecture entitled "Das Mutations Problem" in Vienna (9/25) and his participation in the Second Commission of Eugenics through which he "Voted to admit Germany and all other, properly qualified countries to the Commission" (10/9). Perhaps most remarkably, at the end of that trip, Davenport records a meeting with Charles Darwin's son, Leonard: "At Lewes was met by Darwin and taken to his home in Sussex. Private conference on eugenical matters" (10/20).
 
That engagement carries home, where, in a 1930 diary, he includes a series of relevant newspaper clippings: "Racial related to a Racial Integrity Bill Signed" in Richmond, Virginia (3/14), "Extols African Marriage" (3/4), "Senate Refuses to Shelve Harris Quota Bill: Senate Again Rejects Motion by Glass aimed at Salvaging National origins Clause" (4/24), and "Dr. Adler Closes Psychology Clinic: Noted Viennese Scientist Declared Target of Medical Center Critics" (5/31). In some loose pages associated with that diary, Davenport compares a colleague (simply identified as "Gordon") to the Croatian-American geneticist Milislav Demerec: While Davenport finds Gordon "industrious and fertile in ideas," he adds that he is "not so brilliant as Demerec" (6/3).
 
Davenport's remaining diaries (1931-1944) mostly focus on various trips, with occasional mentions of the outbreak of World War II. The early-1930s feature a series of notebooks dedicated to travel in the Americas, including a "Western Trip" and "Trip to the West by Automobile" (which collectively span July-October 1931), as well as trips to Bermuda, Mexico, and Nova Scotia. The Nova Scotia trip is noteworthy because Davenport explicitly notes an encounter with Russian-American geneticist Theodosius Dobzhansky. In his late-1930s journals, World War II surfaces, if only briefly. In a diary spanning 1937-39, Davenport notes Germany's seizure of Poland (9/1/1939) and Great Britain's subsequent declaration of war (9/3/1939). Curiously, he also alludes to a "Cox: Atomic Nuclear" in multiple entries of June and July in his 1940 diary.
 
Finally, the Davenport diaries are noteworthy for their idiosyncrasies: these include at least one volume authored by his wife, and the eclectic range of ephemera include inside and alongside the diaries. In a volume signed "G.L. Davenport"—and bearing numerous allusions to "Charles and Charlie throughout—Gertrude Davenport records a series of entries between 4/1/1905 to 3/16/1913. Of particular interest is her protest of race track gambling (4/19/1908 and 4/23/1908) and the dedication to Carnegie Lab, with a note of an encounter with Andrew Carnegie, who "disappointed the department by not adding to the endowment" (1/3/1910). Alongside accounts of various farm and house work (mending garments, cleaning, and, unusual for a homemaker, making concrete blocks), this diary also notes Gertrude's reading, namely Harper's Monthly and the Century.
