Graham Chapman

Graham Arthur Chapman was an English comedian, writer, actor, and one of the six members of the surreal comedy group Monty Python. He played authority figures such as the Colonel and the lead role in two Python films, Holy Grail and Life of Brian.

Chapman was born in Leicester and was raised in Melton Mowbray. He enjoyed science, acting and comedy, and after graduating from Emmanuel College, Cambridge and St Bartholomews Medical College, he turned down a career as a doctor to be a comedian. Chapman established a writing partnership with John Cleese, which reached its critical peak with Monty Python during the 1970s. Chapman left Britain for Los Angeles in the late 1970s, where he attempted to be a success on American television, speaking on the college circuit and producing the pirate film Yellowbeard, before returning to Britain in the early 1980s.
