John Devon Roland "Jon" Pertwee (7 July 1919 – 20 May 1996) was an English actor, entertainer and cabaret performer.
Pertwee is most known for starring as the Third Doctor in the science-fiction series Doctor Who between 1970 and 1974. Pertwee also spent 18 years (1959–1977) playing Chief petty officer Pertwee in The Navy Lark on BBC Radio. He later played the title character in the series Worzel Gummidge from 1979 to 1981, and again from 1987 to 1989.
As an actor, Pertwee appeared in many comedy roles and was once described as having "rubbery features and ability to affect silly voices". Earlier in his career, Pertwee had worked as a vaudeville comedian, performed at the Glasgow Empire Theatre and shared a bill with Max Wall and Jimmy James. Towards the end of his life, he performed to audiences in a one-man show called Who Is Jon Pertwee?.
