The John Jacob Abel Collection consists primarily of correspondence (1880-1938). Other series include student notebooks, research notebooks, lab and lecture notes, photographs, addresses and talks, honorary degrees, and awards. The collection also contains press clippings (1883-1940), programs and invitations (1889-1937), and calling cards (1880-1930) that Abel saved throughout his career. Biographical material includes remebrances of Abel by friends and colleagues, information on the life and interests of his wife Mary Abel, and accounts of his early education and pharmacology research. The collection is particularly strong in documenting Abel's research on tetanus, including reprints, articles, experimental notes, editorials, and letters. Additional correspondence with Abel can be found in the personal paper collections of Lewellys Barker, Thomas Cullen, Walter Dandy, William Halsted, Howard Kelly, Adolf Meyer, William Welch, and Lewis Weed.
