1713–1784
A pioneering Quaker teacher and reformer, he became one of the earliest and most persuasive voices against slavery in colonial America. His work in Philadelphia joined education, faith, and activism in a way that influenced later abolitionists on both sides of the Atlantic.
Born in Saint-Quentin, France, in 1713, he came from a Huguenot family that fled religious persecution, first to the Netherlands and then to England before settling in Philadelphia in 1731. There he joined the Quaker community and eventually left business for teaching, a calling that shaped the rest of his life.
He is best remembered as an educator and antislavery campaigner. In Philadelphia he taught for many years and helped create opportunities for students often excluded from formal schooling, including girls and Black children. His writing and organizing made him a central early opponent of slavery in North America, and he helped found a society that defended free Black people who were being illegally held in bondage.
His influence reached far beyond his own classroom. Through essays, pamphlets, and a steady moral argument grounded in Quaker belief, he helped turn antislavery from a private conviction into a public movement. Today he is remembered as a compassionate teacher and one of the foundational figures of American abolitionism.
