Marilyn Monroe (born Norma Jeane Mortenson) was an American actor, model, and singer.

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."

The same year, her images were used as the centerfold and on the cover of the first issue of the men's magazine Playboy. 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).

The Seven Year Itch was also responsible for one of the most iconic images of Monroe.

When the studio was still reluctant to change Monroe's contract, she founded a film production company in late 1954 and named it Marilyn Monroe Productions (MMP). She dedicated 1955 to building her company and began studying method acting at the Actors Studio. In late 1955, Fox awarded her a new contract, which gave her more control and a larger salary. Her subsequent roles included a critically acclaimed performance in Bus Stop (1956) and the first independent production of MMP, The Prince and the Showgirl (1957). Monroe won a Golden Globe for Best Actress for her work in Some Like It Hot (1959), a critical and commercial success. Her last completed film was the drama The Misfits (1961).

In the transcripts of her sessions with Dr. Ralph Greenson, the psychoanalyst she saw towards the end of her life, she admitted to having sexual encounters with actresses Joan Crawford, Barbara Stanwyck, Marlene Dietrich (#Bi2), and Elizabeth Taylor.

Monroe's troubled private life received much attention. She struggled with substance abuse, depression, and anxiety. Her second and third marriages, to retired baseball star Joe DiMaggio and playwright Arthur Miller, were highly publicized, and both ended in divorce. On August 4, 1962, she died at age 36 from an overdose of barbiturates at her home in Los Angeles.
