In 1944, Van Fleet began her professional stage career and immediately distinguished herself in the role of Miss Phipps in the production of
Uncle Harry at the
National Theatre in Washington, D.C. Two years later, in New York, she distinguished herself as well on
Broadway by her performances as Dorcas in
Shakespeare's ''
The Winter's Tale; and yet again, in 1950, as Regan opposite Louis Calhern in King Lear''. Van Fleet's final performance, a brief but "delicious" supporting turn in the
1986 TV adaptation of
Saul Bellow's
Seize the Day, elicited this comment from
Washington Post critic
Tom Shales: Jo Van Fleet, who seems even to walk and blink legendarily, has a tiny part and only two small scenes as Mrs. Einhorn, an old woman with two incontinent dachshunds, but what a piquant impression she makes. ==Personal life and death==
