A number of freed slaves managed to achieve prominence in British society. Ignatius Sancho (1729–1780), known as "The Extraordinary Negro", opened his own grocer's shop in Westminster. He was famous for his poetry and music, and his friends included the novelist Laurence Sterne, David Garrick the actor and the Duke and Duchess of Montague. He is best known for his letters which were published after his death. Others such as Olaudah Equiano and Ottobah Cugoano were equally well known, and along with Ignatius Sancho were active in the abolition campaign.
