Quaker abolitionist and physician in Mt. Pleasant, Ohio, and Schoolcraft, Michigan. Correspondence of Thomas, his wife Pamela S. Brown Thomas, and their children; addresses, autobiography, financial ledgers, and files relating to business activities, medical practice, and anti-slavery activities.
The collection is divided into two series: Correspondence and Other papers: anti-slavery, medical practice, and family.
The correspondence is of Thomas, his wife Pamela S. Brown Thomas, their children Ella, Malcolm, and Stanton, and relatives, friends, public leaders, abolitionists, and publishers. These letters deal largely with family affairs, land transactions, medical discoveries, woman suffrage, the Liberty Party, and Thomas's anti-slavery activities. There are also letters of Stanton B. Thomas while a student at the University of Michigan (1859-1864) and Civil War letters of S. B. Thayer, medical director of the Merrill Horse Regiment. Other Thomas papers include manuscript addresses, essays and other papers; a manuscript autobiography of Thomas; three account books, 1832-1879, pertaining mainly to his medical practice and other business affairs. Of interest is a prospectus for a newspaper, the American Freeman, which lists Schoolcraft area subscribers.
