Born and raised in Los Angeles, Monroe spent most of her childhood in foster homes and an orphanage and married at the age of sixteen. While working in a radioplane factory in 1944 as part of the war effort, she was introduced to a photographer from the First Motion Picture Unit and began a successful pin-up modeling career. The work led to short-lived film contracts with Twentieth Century-Fox (1946–1947) and Columbia Pictures (1948). After a series of minor film roles, she signed a new contract with Fox in 1951. Over the next two years, she became a popular actress and had roles in several comedies, including As Young as You Feel and Monkey Business, and in the dramas Clash by Night and Don't Bother to Knock. Monroe faced a scandal when it was revealed that she had posed for nude photos before she became a star, but the story did not tarnish her career and instead resulted in increased interest in her films. By 1953, Monroe was one of the most marketable Hollywood stars; she had leading roles in the noir film Niagara, which focused on her sex appeal, and the comedies Gentlemen Prefer Blondes and How to Marry a Millionaire, which established her star image as a "dumb blonde". Although she played a significant role in the creation and management of her public image throughout her career, she was disappointed when she was typecast and underpaid by the studio. She was briefly suspended in early 1954 for refusing a film project but returned to star in one of the biggest box office successes of her career, The Seven Year Itch (1955).
