An (abridged) List of Fosse and his Ladies

Bob Fosse was a womanizer from the time he was in high school; as a teenager, he started becoming involved with older women while he performed at nightclubs. As noted in Broadway, the Golden Years: Jerome Robbins and the Great Choreographer-Directors, 1940-Present, Fosse was named in the divorce suit between a waitress in her thirties and her husband, a serviceman in World War II. While he was overseas, the waitress had an affair with Fosse; he was fifteen at the time. As he got older, his behavior did not change. Some of the many women Fosse had in his life were important, in some capacity, to the theatre world, so they are worth mentioning here.

• Mary Ann Niles: Fosse's first wife, the two met on the national tour of Call Me Mister in 1947. They started a "Fosse and Niles" dance act, and were married for two years.
• Joan McCracken: Fosse's second wife, they met while he was married to Niles. She encouraged him to broaden his horizons, take acting classes, and he was soon chosen soon after to understudy the lead role in Pal Joey on Broadway. She also helped to secure him his choreography job on Pajama Game.
• Gwen Verdon: Fosse's third wife and a major collaborator in his work; she's so influential, their relationship is getting a separate post. 
• Ann Reinking: One of Fosse's major girlfriends, and an exemplary Fosse-style dancer. In All That Jazz, the semi-autobiographical movie Fosse made in 1979, she essentially plays herself.
• Other women of note: Jessica Lange, Julie Hagerty, and Ilse Schwarzwald
