Trained as an anthropologist under Frank Speck at the University of Pennsylvania, the ethnohistorian George Snyderman (1908- ) spent his career studying Seneca Indian religion, history, and culture. Snyderman edited the previously unpublished diaries of Halliday Jackson and John Phillips, Quaker missionaries to the Senecas in the late 18th and early 19th century. The Snyderman Papers includes a small volume of correspondence, along with manuscripts of works by Snyderman and colleagues, and copies of primary source materials pertaining to Seneca history. Of particular interest is his correspondence with anthropologists William N. Fenton, Merle Deardorff, and Frank Speck and with his Seneca consultant Clara Redeye and her daughter, Helen Harris, and photographs of the Allegany Senecas taken by Fenton and Speck.

The most stellar member of a stellar family, Elisha Kent Kane was among the most popular American explorers of the mid-nineteenth century, a hero in the tragic mode. Born in Philadelphia in 1820, the son of John Kintzing Kane and Jane Duval Leiper, Kane studied medicine at the University of Pennsylvania before earning a commission as a naval surgeon. While in the Navy, Kane embarked on the succession of voyages to exotic locales that became the basis for his extraordinary fame. In 1843, he attended Caleb Cushing's first diplomatic mission to China as ship's physician, and subsequently traveled to the Philippines and Western Africa. Distinguishing himself in the Mexican War, Kane's greatest fame came from two expeditions to the arctic, aiming to locate the lost explorer, Sir John Franklin and to explore for evidence of the open polar sea. Kane died in 1857 while attempting to organize a third arctic voyage. Part of the Kane Family Collection, the Papers of Elisha Kent Kane contain a mix of personal and family correspondence with correspondence relating to all of Kane's explorations. Intelligent, articulate and very much a romantic, Kane's letters are expressive and passionate. The collection provides fine documentation of youth, his relationship with the Spiritualist Margaret Fox, and of course his travels to China and off the coast of Africa in 1846. Kane's two expeditions to the arctic are particularly well documented, with correspondence, notes, logbooks, diaries, and sketches, as well as Kane's post-expedition notes, writings, and lectures recounting his experiences.
