Some Famous People called William Cosby
William Cosby
Brigadier-General William Cosby (1690–1736) was an Irish soldier who served as the British colonial governor of New York from 1732 to 1736. During his short term, Cosby was portrayed as one of the most oppressive governors in the Thirteen Colonies. In 1735, Cosby accused publisher John Peter Zenger of sedition and libel for publishing unflattering reports about Cosby. In spite of Cosby's efforts, Zenger was acquitted of all charges and the case helped to establish the concept of freedom of the press.
