Marilyn Monroe: A Detailed Biography

Marilyn Monroe (1926–1962), born Norma Jeane Mortenson, was the American actress, model, and singer who became the ultimate Hollywood sex symbol. Famous for breathy voice, platinum blonde curls, and roles in Gentlemen Prefer Blondes and Some Like It Hot, her vulnerable persona masked a troubled life of foster homes, mental health struggles, and failed marriages. Her mysterious death at 36 cemented her as a cultural icon. This biography covers her unstable childhood, rise to stardom, marriages to Joe DiMaggio and Arthur Miller, Kennedy rumours, and tragic end, as documented by the Encyclopaedia Britannica, the Official Marilyn Monroe Site, and the Smithsonian Magazine.

Early Life as Norma Jeane

Birth in Los Angeles

Born Norma Jeane Mortenson on June 1, 1926, in Los Angeles County Hospital to Gladys Pearl Baker (mental illness) and unknown father (possibly Charles Stanley Gifford). Gladys was unstable; Norma Jeane spent childhood in foster homes and orphanages, as detailed by the History.com.

Marriage to James Dougherty and Modelling

At 16, to avoid returning to orphanage, Norma Jeane married merchant marine James Dougherty in 1942. During WWII she worked in a munitions factory where an Army photographer discovered her. Signing with a modelling agency in 1945, she dyed her hair blonde and changed her name to Marilyn Monroe, as documented by the Library of Congress.

Hollywood Breakthrough

Gentlemen Prefer Blondes and Some Like It Hot

Signed with 20th Century Fox in 1946, small roles led to stardom in Gentlemen Prefer Blondes (1953) and How to Marry a Millionaire (1953). Some Like It Hot (1959) — “I wanna be loved by you” — is considered her finest performance, as preserved by the BFI.

Marriages and Relationships

Joe DiMaggio and Arthur Miller

Married baseball star Joe DiMaggio in 1954 — the famous subway grate scene from The Seven Year Itch (1955) contributed to their divorce after 9 months. Married playwright Arthur Miller in 1956; their troubled relationship inspired The Misfits (1961). Rumours of affairs with JFK and RFK persist but are unproven, as detailed by the Vanity Fair.

Mental Health and Substance Abuse

Marilyn struggled with anxiety, depression, and addiction to barbiturates and amphetamines. She was briefly institutionalised in 1961.

Death

On August 4, 1962, Marilyn was found dead in her Brentwood home — naked, phone in hand, empty pill bottles nearby. Official cause: probable suicide by barbiturate overdose. Conspiracy theories (CIA, Kennedys, Mafia) remain popular but lack evidence, as documented by the Los Angeles Times Archives.

Personal Life

Marilyn had no children despite multiple miscarriages. She converted to Judaism for Miller. Famous for being late to set and memorising lines with difficulty.
