[1] Born 5 January 1951, on the eastern Caribbean island of St. Kitts, Fox emigrated to London, England, with his family when he was one year old.
Joe Weider sponsored Fox's move to Los Angeles in 1981, and he competed in IFBB contests for the next 13 years.
Bill Reynolds, then Flex magazine editor-in-chief, gave Fox the nickname "Brutal Bertil" for his high-volume and extremely heavy training.
Fox placed second in two IFBB shows – the 1982 Night of Champions and the 1983 Swiss Grand Prix (beating Lee Haney) and he finished fifth in the 1983 Mr. Olympia (his second of five Mr. O appearances).
[2][3][4][5][6] On 4 August 2022, Fox was pardoned by the Governor General of St. Kitts and Nevis after serving 25 years and is now a free man living in the UK.
