Short answers, pulled from the story.
Marilyn Monroe was born Norma Jeane Mortenson on the 1st of June 1926, at Los Angeles General Hospital in the Boyle Heights neighborhood of Los Angeles. The stage name Marilyn Monroe was chosen in 1946 by 20th Century-Fox executive Ben Lyon, who picked the first name after Broadway star Marilyn Miller, while Monroe supplied her mother's maiden name as the surname.
Marilyn Monroe died on the 4th of August 1962, at her home at 12305 Fifth Helena Drive in Brentwood, Los Angeles, from acute barbiturate poisoning. The toxicology report found 8 mg% of chloral hydrate and 4.5 mg% of pentobarbital in her blood, and 13 mg% of pentobarbital in her liver, dosages several times the lethal limit. Deputy coroner Thomas Noguchi classified her death as a probable suicide.
Monroe's breakthrough came in 1953 with three films: the noir Niagara, the musical comedy Gentlemen Prefer Blondes, and How to Marry a Millionaire. Her Golden Globe-winning performance in Some Like It Hot (1959) is considered the peak of her comic work, and her final completed film, The Misfits (1961), is now regarded as her most dramatically mature performance.
Monroe was married three times. She first married factory worker James Dougherty on the 19th of June 1942, at age sixteen, divorcing him in September 1946. She married retired New York Yankees star Joe DiMaggio at San Francisco City Hall on the 14th of January 1954; they divorced after nine months. Her third husband was playwright Arthur Miller, whom she married on the 29th of June 1956, in a civil ceremony in White Plains, New York; they divorced in January 1961.
Marilyn Monroe Productions (MMP) was an independent film company Monroe founded in late 1954 with photographer Milton Greene. Monroe created it because 20th Century-Fox's head executive Darryl F. Zanuck had kept her contract unchanged since 1950, paying her far less than her box office value and blocking her from roles outside the pin-up type. The company produced The Prince and the Showgirl (1957) and forced Fox to grant Monroe a new contract giving her the right to choose her own projects, directors, and cinematographers.
In March 1952, Monroe publicly acknowledged that she had posed for nude calendar photographs in 1949, taken by photographer Tom Kelley for John Baumgarth calendars. Monroe and Fox decided to admit to the photographs while stressing that she had been broke at the time, a strategy that produced public sympathy and increased audience interest in her films. The same photographs were later used by Hugh Hefner as the centerfold and cover image of the first issue of Playboy in December 1953, without Monroe's consent.
