Olaudah Equiano (Gustavas Vassa) was captured as a slave from Nigeria in West Africa as a child and served under serveral masters in the Caribbean and America. He was owned for a short period by a wealthy Philadelphia Quaker Merchant and slave dealer named Robert King, who belonged to Arch Street Meeting. Because of Equiano’s Intelligence, King trained him to be a clerk. He observed the misery of other slaves held bondage. After gaining his freedom, he settled in London, England, where he wrote “The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa” in 1789. His autobiography helped the British government abolish slavery in Great Britian.
