How Norma became Marilyn Monroe
When Norma Jeane signed her first studio contract with 20th Century-Fox in August 1946, she and executive Ben Lyon chose her new name together. Lyon suggested "Marilyn" because she reminded him of the Broadway star Marilyn Miller. "Monroe" was her mother's maiden name.
Before that she had already tried other names. As a model she sometimes worked as Jean Norman, and she used "Mona Monroe" for nude photographs. Marilyn Monroe stayed a stage name for nearly ten years. She changed it legally on 23 February 1956.
