International vaudeville star and Broadway prima ballerina Jeanne Devereaux performed for millions across Europe and America in her prime. Born Jean Helman, she entered showbiz young as a trouper performing in palatial theaters and was one of the last vaudevillians surviving into the 2010s. In her final years she indulged her passion for research and writing in the Huntington Library's Rothenberg Reading Room, losing none of her intelligence and wit despite a failing memory. Drawing on interviews, show programs and her personal diary and letters, this biography illuminates the life and career of one of vaudeville's stars of stage, film and television.
