Descended from German Quakers who immigrated to Pennsylvania in the late seventeenth century, Elisha Tyson was born in 1749. As a young man he became wealthy in the milling business in northeastern Maryland before moving in the early 1780s to Baltimore, where he grew even wealthier and established a reputation as a prominent member of the city's business community. Over the course of more than three decades in the late eighteenth and early nineteenth centuries, Tyson helped found abolition societies, supported schools for free Black children, and contributed to the creation of numerous Black institutions and benevolent societies. He filed freedom petitions on behalf of enslaved people and pushed for the passage of liberalized manumission laws in Maryland. He used some of his fortune to assist Black people who claimed they were illegally held in bondage to sue for their liberty, and he confronted slave traders who kidnapped free Black Americans with the aim of selling them into slavery. By the time he died in February 1824, Elisha Tyson had personally aided in the liberation of perhaps two thousand Black people.

Yet the only biography published about this remarkable man was penned shortly after his death by John Shoemaker Tyson, Elisha Tyson's nephew. In this volume, Joshua D. Rothman-a preeminent historian of slavery and abolition-seeks to remedy that silence. Along with an annotated version of that nineteenth-century biography, Rothman provides a thorough introduction to Elisha Tyson's religious, political, and ideological worlds as well as a set of selected documents that illuminate some of Tyson's work.
