François Duvalier (14 April 1907 -- 21 April 1971), also known as 'Papa Doc' Duvalier, was the President of Haiti from 1957 until his death in 1971. He opposed a military coup d'état in 1950, and was elected president in 1957 on a populist and black nationalist platform. His rule, based on a purged military, a rural militia known as the Tonton Macoute and the use of a personality cult and voodoo, resulted in the murder of an estimated 30,000 Haitians and the exile of many more. Ruling as President for Life from 1964 until his death in 1971, Duvalier was initially known for successfully fighting diseases, gaining him the nickname 'Papa Doc' ("Daddy Doc[tor]" in French).
