Anderson Ruffin Abbott
Anderson Ruffin Abbott, M.D. was the first Black Canadian to be a licensed physician. His career included participation in the American Civil War.
Abbott was born in Toronto as the son of Wilson Ruffin Abbott and Ellen Abbott. The Abbotts were a prominent black family in Toronto who had left Alabama as free people of color after their store had been ransacked. After living a short time in New York, they relocated to Upper Canada in 1835 or 1836. Wilson Abbott soon began to purchase real estate in and around Toronto. He owned 48 properties by 1871 and also became active in politics.
