The Cassin diaries are contained in six volumes. The first, spanning 1865-66, documents his travel by steamer. Cassin records crossing the equator (7/30/1865), visiting a volcano at Cape Verde (7/25/1865), and arriving in Brazil. Enterprising researchers might research his course using the longitudes and latitudes he records throughout this volume.
 
The second volume picks up more than a year later and commits significant attention to the medical profession. The first entry voices concern about the medical department at the University of Pennsylvania (12/10/1868), and subsequent pages enclose copies of letters from 1869, including his committee appointments, especially Assistant Surgeon in the Navy (4/2/1869). Sequential entries begin in earnest on 5/6/1869, when Cassin recounts his travels aboard the brig Ohieflaua from the Chicago Harbor to Lake St. Clair.
 
Cassin's third and fourth volumes are less descriptive but remarkable for the extent of his travels. In his 1870 "New York" diary, Cassin notes another journey to Brazil in June, South China Sea in August, and Hong Kong and Shanghai in September. His 1870-71 diary dovetails with the latter, recording a trip to Rio de Janeiro (6/6/1870) and undated notes pertaining to a voyage to South Africa. Once again, Cassin captures many longitudes and latitudes.
 
The "Clayton's Octovo Diary 1872" is perhaps the richest from an ethnographic perspective. Cassin provides detailed accounts of visits to Key West (2/10/1872), Havana and Matanzas (between February and April 1872), and even a brief reflection on the act of journaling. "A diary is something like a resolve to call professionally on a dentist
 
you may keep it, but the chances are much in the favor of your putting it off," Cassin observes on 4/26/7182. "Diary writing is almost the stupidest thing that I know of, unless one can make a writing task in no other way." Between May and June 1872, he travels throughout the Caribbean, furnishing descriptions of the peoples and villages he encounters. Interested researchers will find a particularly evocative entry of Key West society women in a 6/21/1872 quotation below.
 
A Pocket Diary dated 1875, finds Cassin landlocked, maintaining a more traditional journal of meetings, calls, letters, and weather conditions. The volume opens in St. Louis where he has apparently purchased a home, and it is not until September that he begins to travel again. That fall he returns to Brazil (11/6) and visits Uruguay (12/1).

Serving as a U.S. Navy physician, Charles Luke Cassin traveled extensively, recording firsthand accounts of Brazil, Canada, South Africa, the South China Sea, and the Caribbean during the postbellum period. His six-volume journal, which spans 1865-1875, offers glimpses at those far flung locations and the various peoples who inhabited them. Cassin's journals ought to appeal to a wide range of researchers, including those interested in the history of seafaring, the West Indies, ethnography, and late-eighteenth-century medical practices.

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.
 

Researchers interested in Haney's biography will find that these volumes meticulously document his education, literary interests, and career. Volumes from the 1890s capture his voracious reading habits. For example, in August 1895, he reads and comments upon Charles Darwin's Descent of Man (8/11) and the Bible (8/18) in the same week. Throughout his journals, Haney provides a useful homespun index at the end of each journal. Beginning in 1898, he adds annual reviews in which he takes stock of his progress. (Those reviews become so exhaustive that, by 1907, he begins adding subcategories of assessment, such as "My Relation to the World At Large," "Literary Work," "Travel," "People Whom I Met," "Drama & Music," "Reading," "Financial," "Family Affairs"). Scholars interested in Philadelphia regional history will note that these early volumes recount Haney frequent visits to book dealer A.S.W. Rosenbach, during which the two discuss books and university affairs (e.g. 6/10/1896, 8/17/1899).
 
Haney's professional career begins in earnest in 1900, when he accepts his position at Central High School. While he acknowledges the significance of the offer at the time (6/29/1900), Haney reflects at greater length in a later entry (9/4/1935). In that year's annual review, he summarizes his progress: "I am inclined to regard 1900 as the most significant year thus far…the development of the bibliography, our experience at Washington and New York
 
the completion of my first novel
 
the work on my thesis
 
my appointment at the High School--truly a diversified array of interests." While Haney's bibliography of Coleridge wouldn't be published for some time (he celebrates receipt of his copy on 9/1/1903), the next twenty years bring significant milestones in his career: Haney becomes department chair (1905 review) and, after a "strenuous campaign," is elected president of Central High School (1920 review).
 
Alongside his literary interests, Haney proves a studious observer of contemporary economics and world affairs. Although he evinces sympathies for laissez-faire capitalism (reference an excerpt from the 1926 annual review), Haney records labor strikes from the 1890s (12/17-18/1895 and 1/3/1896), Black Tuesday (10/29/29, 1929 annual review), and the lived experience of the Great Depression (1930-34 annual reviews). Haney also visits the Chicago World's Fair (1933 review) and discusses the Blizzard of 1899 (2/10/1899), Charles Lindbergh's transatlantic flight (5/21/1927), the discovery of Pluto (1930 review), Hughes' flight around the world (1938 review), and Russia's launch of a satellite, which he calls a "catastrophe for the West" (1957 review).
 
Haney also demonstrates a sustained interest in domestic (Republican) politics. After the McKinley assassination, he recounts reports of news over almost two weeks (9/7-9/19/1901). He reports considerable excitement concerning President Roosevelt's visit to CHS (11/12/1902), and celebrates the electoral gains of our "virile president" (11/9/1904). (Haney thinks less highly of President Wilson.) He records ratification of women's suffrage (1920 annual review), repeal of 18th Amendment, and passage of the 20th and 21st Amendments (1933 review). A tireless critic of F.D.R., Haney bemoans his election (11/8-9/1932) and reelections (1936 review, 11/6/1940, 11/8/1944), needling his "imprudent Supreme Court Packing idea" (1937 review) and fretting that, "A new American Gestapo set up in Washington is ready to hound any citizen who criticizes the Government" (1944 review). In fact, Haney's critiques of F.D.R. offer a window into conservative backlash against the New Deal, as excerpted in Selected Quotations (1935 review). In one of his final journals, he also notes the emergence of new racial coalitions associated with the Civil Rights era, writing, "The Negroes, once grateful to the G.O.P. for bringing about their liberation in the South, have turned their backs on the Republicans and cheerfully vote for politicians who given them untold millions in 'relief' of every sort" (1957 review).
 
Finally, war historians will discover countless accounts of U.S. military activity between the Spanish-American War and World War II. Haney celebrates the destruction of Pascual Cervera y Topete's naval fleet (7/4/1898), and notes with increasing alarm the "gathering war clouds in Europe" (7/30/1914, 1914 annual review). In his next annual review, he mourns Western civilization: "The year 1915 has probably been the most discreditable year since the dawn of civilization-discreditable to civilization and to all that such a state of existence implies. The Great European War, begun about August 1st of the previous year, ran a full twelve-month of slaughter during 1915 with no end in sight…The good name of Germany and of the Teutonic culture has been thrown to the winds. The future of the world's peace demands the defeat of the power that stands for militarism and for brute force" (1915 review). Haney marks Armistice Day as "one of the remarkable days of my life" (11/11/1918), but he soon finds himself profoundly disappointed with reconstruction efforts, as excerpted in Selected Quotations (1920 annual review). Haney's 1920s and 1930s entries offer a sobering account of the failures of League of Nations and the rise of Hitler and Mussolini. His volumes record milestones of World War II, from the attack on Pearl Harbor (12/7/1941) to the bombing of Hiroshima (8/6-7/1941). "It was epochal," writes Haney. "Papers & radio features the devastating atomic bomb. A new age has begun" (8/7/1941).

John Louis Haney papers contain 33 volumes that Haney maintained from the age of 10 until a year before his death (1887-1959). The first twelve volumes are devoted to his educations (including Sunday School, German School, and the University of Pennsylvania), whereas subsequent volumes trace his career as professor of English (1900-1920) and president of Philadelphia's Central High School (1920-1943), during which Haney published numerous books on Coleridge and Shakespeare. These volumes may interest a host of different scholars—certainly those exploring twentieth-century education and the field of literary criticism—but well as those researching the Great Depression, the 1933 World's Fair, twentieth century U.S. politics (particularly for conservative critique of F.D.R.), the institutional history of the American Philosophical Society (in which Haney was elected a member in 1929), and the history of the Spanish-American War, World War I, and World War II. Researchers may also choose to mine this collection for its rich ephemera, including self-portraits interspersed in diaries (e.g. 1898, 1904-6, 1910-13, 1918-22), as well as an ancillary book of newspaper clippings, a folder of other ephemera, and two volumes of his personal reading lists.

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.
