Pierre Toussaint The Venerable Pierre Toussaint (27 June 1766 – June 30, 1853) was a former slave from the French colony of Saint-Domingue who was brought to New York City by his owners in 1787.

Freed in 1807 after the death of his mistress, Pierre took the surname of "Toussaint" in honor of the hero of the Haitian Revolution which established that nation.
