Norma Jeane Mortenson, or as we all know her – Marilyn Monroe was an American actress, model, and singer, who became a major sex symbol, starring in a number of commercially successful motion pictures during the 1950s and early 1960s.
After spending much of her childhood in foster homes, Monroe began a career as a model, which led to a film contract in 1946 with Twentieth Century-Fox.
Monroe had three marriages, all of which ended in divorce. The first was to James Dougherty, the second to Joe DiMaggio, and lastly to Arthur Miller.
It is claimed she was briefly married to writer Robert "Bob" Slatzer. She is alleged to have had affairs with both John and Robert Kennedy (Monroe was in love with President Kennedy and wanted to marry him; but when the married president ended their affair, Monroe became depressed, and turned to Robert Kennedy, who reportedly visited Monroe in Los Angeles the day that she died).
Marlon Brando, in his autobiography Songs My Mother Taught Me, claimed that he had had a relationship with her, and that they remained friends until her death. She also suffered two miscarriages and an ectopic pregnancy during her three marriages.
The final years of Monroe's life were marked by illness, personal problems, and a reputation for unreliability and being difficult to work with.
The circumstances of her death, from an overdose of barbiturates, have been the subject of conjecture. Though officially classified as a "probable suicide", the possibility of an accidental overdose, as well as of homicide, have not been ruled out. Many theories, including murder, circulated about the circumstances of her death and the timeline after the body was found. Some conspiracy theories involved John and Robert Kennedy, while other theories suggested CIA or Mafia complicity. It was reported that President Kennedy was the last person Monroe called.
