Jack Cannot

John Valentine Cannot, better known as Jack Cannot (1883–1929), was an English-Australian comic of stage and screen.

He was born in England and eventually went to South Africa where he toured for two years in various stage productions, including The Merry Widow. He then moved to Australia in 1910 under contract to J. C. Williamson Ltd. They used him in pantomimes such as Jack and the Beanstalk as well as various musical comedies.

The advent of talking films made it more difficult for him to find work and he was in financial distress. Cannot later killed himself with strychnine at Maroubra Beach.
