Who was known for his promotion of inoculation for disease prevention and owned the slave Onesimus?
Onesimus (Boston slave) Onesimus (late 1600s–1700s) was an African-born man held as a slave by Puritan minister Cotton Mather, who helped mitigate the impact of a smallpox outbreak in Boston by introducing Mather to the principle of inoculation. In a 2016 "Boston Magazine" survey, he was declared one of the "Best Bostonians of All Time".
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. There he eventually gained his freedom and became a noted philanthropist to the poor of the city. 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.
