From a geographical trip of the American Geographical Society of New York to the west coast, Frank Spooner Churchill furnishes firsthand accounts of national parks and the U.S. west at the turn of the twentieth century. Maintained on various scraps of paper contained in six folders—some of them addressed to his wife and son—Churchill records a month of travels in significant detail (8/28-10/5/1912). He visits major national parks (many of which listed in Locations), and tours a number of U.S. cities, including San Francisco, where he discusses the 1906 earthquake, and Salt Lake City, where he visits a Mormon church (9/24/1912). Notably, Churchill enthusiastically explores indigenous sites, including Indian burial mounds near Saint Louis (8/28/1912) and a pueblo outside Santa Fe (9/29-9/30/1912). Throughout his travels by automobile, train, and boat, Churchill proves a studious observer of travelers. He talks presidential politics with his hosts (9/1/1912), records a lengthy entry on an "attractive fellow" named Baldwin (9/11/1912), and even muses about the differences between European and American men, the latter whom "talk little and do much" (9/16-18/1912). Finally, researchers interested in early-twentieth century material culture will discover a bounty of ephemera interwoven with his entries, including a telegram, a brochure from Lake Washington, newspaper clippings Seattle Daily Times, San Francisco Chronicle, Denver Post, and dozens of other items in the box.
 

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.

The majority Vaux diaries are maintained at least two generations of George Vaux (1800-1927). Those volumes include entries that may interest researchers investigating late-antebellum politics, religion, and Vaux family history (1854-59 diaries), postbellum weather and meteorological observations (1853-1915 daybooks), late-nineteenth century architecture and urban development ("Llsyfran Diary," 1886-1915), and the religious practices of American Friends in the nineteenth century (1825-1927 and 1886-1901 diaries). However, there are also noteworthy volumes from William Vaux, Richard Vaux, Samuel Sansom, and Mary Vaux.
 
William Vaux
 
The diaries of William Vaux (1883-1908) may interest researchers exploring Philadelphia regional history, western expeditions, late-nineteenth century science (especially photography), late-nineteenth century presidential politics, and the 1893 World's Fair, for which Vaux includes a dedicated volume. In addition to accounts of education, marriage, funerals, and the religious practices of the Philadelphia Yearly Meeting, William Vaux offers at least one account of Brigham Young and the Mormons (1883 diary). Most volumes emphasize his participation in university life (Haverford College and the Drexel Institute), athletics (the American Alpine Club), and postbellum science (the Photographic Society of Philadelphia, the Quaker Asylum and Penitentiary), with occasional notes pertaining to presidential politics, such as the election and assassination of William McKinley.
 
Richard Vaux
 
Two volumes contained in the Richard Vaux papers warrant careful attention. A typed transcript of a 1781 diary (1/1-10/27) furnishes an account of a loyalist during the American Revolution. As detailed in George Vaux's short introduction to the diary, Vaux apprenticed with Samuel Sansom in Philadelphia beginning in 1768. (The original diary, which begins in March 1779 is unavailable.) A loyalist, he spent much of the war in London and returned to Philadelphia shortly after the revolution (c. 1784). Each entry includes paragraph-length account of personal affairs of and socializing with the English upper class, typically beginning with breakfast meetings and running until often quite late at night (usually Vaux notes that he returns home around 11 or midnight, though several entries are much later). Typical social events include breakfasts and dinners (and the individuals involved), pipe smoking, excursions around England, theater showings (e.g. Covent Garden Play House), daily visits to coffee shops (especially Lloyd's Coffee House), painting exhibitions (including the work of Benjamin West), and the Free Mason Lodge. As George Vaux notes in his introduction, Richard is a "man of the world." He also spends a fairly extraordinary amount of time and money on inns and taverns (including Ambrose Lloyd's, Queens Head Tavern, Bull Tavern, March's Tavern, and Falcon Inn). Equally descriptive are his meticulous accounts of expenses: coffee houses and coaches are the most frequent expenses, though Richard Vaux also notes spending on charity, tobacco, tea, newspapers, baths, books, brandy, and milk.
 
Beginning in September 1781, Richard Vaux embarks on a transatlantic voyage, during which he measures daily progress (distance traveled) and coordinates (latitudes). His time on board is marked by ubiquitous illness, particularly sea sickness, injuries, and fevers. The reader also gains a rich sense of the sailors' diets (including pickled tongues) and daily trials (e.g. pests, as Richard records "dismal nights with the bugs" on multiple occasions, including 10/8 and 10/16). Notably, the narrative ends when the ship is boarded by the Hendrik Privateer, a New England ship under the command of Thomas Bensom, which seizes their brig as a "prize to America" and ransacks their stores (10/26).
 
Samuel Sansom
 
Also included in the Richard Vaux papers is the European travel journal of Samuel Sansom (1759-1760), which provides some of the lengthiest, most conversational, and public-facing diary entries researchers will encounter anywhere in the APS collections. The Sansom diary opens with a note from his former apprentice, Richard Vaux, and other front matter suggests that the journal was transcribed at sea from loose pages so that the author could enable his friends to "partake with him in the entertainment he experiences (in the days of his youth)." The volume also features an excerpt from Elizabeth Drinker's journal with a silhouette of Sansom and a note that Sansom left London on 4/1/1760 and returned to Philadelphia on 5/4/1760.
 
Sansom's account begins at the outset of his transatlantic journey, and pays significant attention to travel delays
 
in fact, leaks require his ship to return to Philadelphia just nine days after departure. Upon arriving in London, Sansom travels widely and socializes continuously, particularly with the English upper class. He attends Quaker meetings, frequents coffee houses, and he is preoccupied with various curiosities, from wax figures (11/13/1759) to a dwarf and giant (2/22/1760). Sansom proves a studious observer of the mechanics of production (e.g. grist mills), English towns and cities (especially Birmingham), and Quaker sermons and religious practices. He regularly intersperses prosaic observations with grand musings (reference the 12/20/1759 and 2/1/1760 entries for examples) intended to instruct and delight the friends he imagines will later read his volume with rapt anticipation.
 
Mary Vaux
 
Finally, the Mary Walsh James Vaux maintained a diary in 1906 and for most of the period spanning 1921-1951. Those 40 volumes may interest researchers interested in women's history, Philadelphia regional history, Vaux family history, western expeditions, and the outbreak of WWII. Vaux's diaries include inspirational quotes, notes from religious meetings, lectures, and receptions, shopping lists, addresses, and notes on the weather. Her entries frequently reference the Pennsylvania Yearly Meeting (Society of Friends) as well as the League of Women Voters, Female Society for the Relief and Employ of the Poor, and the Salvation Army. Diaries sometimes include ephemera, such as dried leaves and photographs (1927).
 
Although Mary Vaux tends to record cursory notes, sometimes her entries provide insights into her emotional state. Vaux appears to have suffered from depression (reference, for example, 10/29/1927, 11/3/1927, 11/13/1939, and 5/4/1940) and often register significant shifts in mood (compare 9/24/1906 to 11/4/1906). A notebook also appears to include numerous personal letters Mary Vaux collected from her husband, George Vaux, spanning 1932-34. (Each entry begins, "George Vaux is here to speak to Mary"). World War II surfaces in her later diary entries. While Mary Vaux rarely discusses politics or war, her 1940 Pomernatz diary includes draft numbers in place of the 10/27-29 entries. The 12/7/1941 entry in her Excelsior diary and the 12/8/1941 entry in her Pomernatz diary note the outbreak of World War II.

The sprawling Vaux Family Papers include at least 160 volumes of diaries traversing two centuries of American history (1759-1951). While those journals are maintained predominantly by generations of George, Richard, and William Vaux the collection is bookended by Richard Vaux (1781) and Mary Walsh James Vaux (1906-1951), both of whom supply some of the most surprising records in the collection. (In fact, the Vaux family included some 10 Georges, three Richards, and two Williams.) Reading across these papers, researchers will discover accounts of early American religion during the Second Great Awakening (especially the Society of Friends and the Church of Jesus Christ of Latter-day Saints), European towns and cities between the eighteenth and nineteenth centuries, late-nineteenth century conservation (with accounts of 1880s Yosemite and Theodore Roosevelt), ante and postbellum U.S. politics (including short-lived factions such as the Locofocos), the fields of business, architecture, and photography, and women's history.
 
The majority Vaux diaries are maintained at least two generations of George Vaux (1800-1927). Those volumes include entries that may interest researchers investigating late-antebellum politics, religion, and Vaux family history (1854-59 diaries), postbellum weather and meteorological observations (1853-1915 daybooks), late-nineteenth century architecture and urban development ("Llsyfran Diary," 1886-1915), and the religious practices of American Friends in the nineteenth century (1825-1927 and 1886-1901 diaries). However, there are also noteworthy volumes from William Vaux, Richard Vaux, Samuel Sansom, and Mary Vaux.

The diaries of William Vaux (1883-1908) may interest researchers exploring Philadelphia regional history, western expeditions, late-nineteenth century science (especially photography), late-nineteenth century presidential politics, and the 1893 World's Fair, for which Vaux includes a dedicated volume. In addition to accounts of education, marriage, funerals, and the religious practices of the Philadelphia Yearly Meeting, William Vaux offers at least one account of Brigham Young and the Mormons (1883 diary). Most volumes emphasize his participation in university life (Haverford College and the Drexel Institute), athletics (the American Alpine Club), and postbellum science (the Photographic Society of Philadelphia, the Quaker Asylum and Penitentiary), with occasional notes pertaining to presidential politics, such as the election and assassination of William McKinley.
 
Richard Vaux
 
Two volumes contained in the Richard Vaux papers warrant careful attention. A typed transcript of a 1781 diary (1/1-10/27) furnishes an account of a loyalist during the American Revolution. As detailed in George Vaux's short introduction to the diary, Vaux apprenticed with Samuel Sansom in Philadelphia beginning in 1768. (The original diary, which begins in March 1779 is unavailable.) A loyalist, he spent much of the war in London and returned to Philadelphia shortly after the revolution (c. 1784). Each entry includes paragraph-length account of personal affairs of and socializing with the English upper class, typically beginning with breakfast meetings and running until often quite late at night (usually Vaux notes that he returns home around 11 or midnight, though several entries are much later). Typical social events include breakfasts and dinners (and the individuals involved), pipe smoking, excursions around England, theater showings (e.g. Covent Garden Play House), daily visits to coffee shops (especially Lloyd's Coffee House), painting exhibitions (including the work of Benjamin West), and the Free Mason Lodge. As George Vaux notes in his introduction, Richard is a "man of the world." He also spends a fairly extraordinary amount of time and money on inns and taverns (including Ambrose Lloyd's, Queens Head Tavern, Bull Tavern, March's Tavern, and Falcon Inn). Equally descriptive are his meticulous accounts of expenses: coffee houses and coaches are the most frequent expenses, though Richard Vaux also notes spending on charity, tobacco, tea, newspapers, baths, books, brandy, and milk.
 
Beginning in September 1781, Richard Vaux embarks on a transatlantic voyage, during which he measures daily progress (distance traveled) and coordinates (latitudes). His time on board is marked by ubiquitous illness, particularly sea sickness, injuries, and fevers. The reader also gains a rich sense of the sailors' diets (including pickled tongues) and daily trials (e.g. pests, as Richard records "dismal nights with the bugs" on multiple occasions, including 10/8 and 10/16). Notably, the narrative ends when the ship is boarded by the Hendrik Privateer, a New England ship under the command of Thomas Bensom, which seizes their brig as a "prize to America" and ransacks their stores (10/26).
 
Samuel Sansom
 
Also included in the Richard Vaux papers is the European travel journal of Samuel Sansom (1759-1760), which provides some of the lengthiest, most conversational, and public-facing diary entries researchers will encounter anywhere in the APS collections. The Sansom diary opens with a note from his former apprentice, Richard Vaux, and other front matter suggests that the journal was transcribed at sea from loose pages so that the author could enable his friends to "partake with him in the entertainment he experiences (in the days of his youth)." The volume also features an excerpt from Elizabeth Drinker's journal with a silhouette of Sansom and a note that Sansom left London on 4/1/1760 and returned to Philadelphia on 5/4/1760.
 
Sansom's account begins at the outset of his transatlantic journey, and pays significant attention to travel delays
 
in fact, leaks require his ship to return to Philadelphia just nine days after departure. Upon arriving in London, Sansom travels widely and socializes continuously, particularly with the English upper class. He attends Quaker meetings, frequents coffee houses, and he is preoccupied with various curiosities, from wax figures (11/13/1759) to a dwarf and giant (2/22/1760). Sansom proves a studious observer of the mechanics of production (e.g. grist mills), English towns and cities (especially Birmingham), and Quaker sermons and religious practices. He regularly intersperses prosaic observations with grand musings (reference the 12/20/1759 and 2/1/1760 entries for examples) intended to instruct and delight the friends he imagines will later read his volume with rapt anticipation.
 
Mary Vaux
 
Finally, the Mary Walsh James Vaux maintained a diary in 1906 and for most of the period spanning 1921-1951. Those 40 volumes may interest researchers interested in women's history, Philadelphia regional history, Vaux family history, western expeditions, and the outbreak of WWII. Vaux's diaries include inspirational quotes, notes from religious meetings, lectures, and receptions, shopping lists, addresses, and notes on the weather. Her entries frequently reference the Pennsylvania Yearly Meeting (Society of Friends) as well as the League of Women Voters, Female Society for the Relief and Employ of the Poor, and the Salvation Army. Diaries sometimes include ephemera, such as dried leaves and photographs (1927).
 
Although Mary Vaux tends to record cursory notes, sometimes her entries provide insights into her emotional state. Vaux appears to have suffered from depression (reference, for example, 10/29/1927, 11/3/1927, 11/13/1939, and 5/4/1940) and often register significant shifts in mood (compare 9/24/1906 to 11/4/1906). A notebook also appears to include numerous personal letters Mary Vaux collected from her husband, George Vaux, spanning 1932-34. (Each entry begins, "George Vaux is here to speak to Mary"). World War II surfaces in her later diary entries. While Mary Vaux rarely discusses politics or war, her 1940 Pomernatz diary includes draft numbers in place of the 10/27-29 entries. The 12/7/1941 entry in her Excelsior diary and the 12/8/1941 entry in her Pomernatz diary note the outbreak of World War II.

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.
