Biografía

Gave birth to her only child at age 31, a son Jonathan Oppenheim on November 11, 1952. Child's father was her husband, David Oppenheim.

According to biographer Gary Carey, in its search for subversives in the film industry the Un-American House Activities Committee (UHAC) was flummoxed by Holliday, who essentially played her Oscar-winning Nacida ayer (1950) character "Billie Dawn" on the witness stand.

Despite her image as a "dumb blonde", she allegedly had an IQ of 172. She often said that it took a lot of smarts to convince people that her characters were stupid.

To help build up her image, particularly in the eyes of Columbia Pictures chief Harry Cohn, Katharine Hepburn deliberately leaked stories to the gossip columns suggesting that her performance in La costilla de Adán (1949) was so good that it had stolen the spotlight from Hepburn and Spencer Tracy. This got Cohn's attention and Holliday won the part in Nacida ayer (1950).

Following her divorce, she became involved with jazz musician Gerry Mulligan. After learning she had breast cancer, she stopped filming and began writing songs with him. He wrote the music and she wrote the lyrics. Some of these songs appear on the album "Holliday With Mulligan", which they recorded together in 1961. It was not released until 1980, 15 years after Holliday's death.
