Born in London, Kent began her acting career in local productions as a teenager and went on to appear in more than 45 films, with co-stars including Marilyn Monroe and Laurence Olivier. Her television credits included the live musical The Ship in the Bay in 1930s, and laterCrossroads and Lovejoy.
She met her future husband, actor Josef Ramart, on the set of Caravan and the two were married in 1946. Ramart died in 1989.
"I knew Jean for more than 50 years. She was a feisty, funny, outspoken character who never took herself too seriously," said former film critic and close family friend Michael Thornton, who announced her death, according to the BBC. "She knew what it meant to be a star and regarded it as her job to live up to that position and never to disappoint the public."
In 2011, the British Film Institute honored Kent on her 90th birthday, at which point she told the BBC she was still open to acting roles, as long as they didn't involve walking.
