Marilyn 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. 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.
On May 19, 1962, Monroe made her last significant public appearance, singing “Happy Birthday, Mr. President” at a birthday party for President John F. Kennedy at Madison Square Garden. The dress that she wore to the event, specially designed and made for her by Jean Louis, sold at an auction in 1999 for $1.26 million.
Monroe reportedly had an affair with President Kennedy. Journalist Anthony Summers examines the issue of Monroe’s relationships with the Kennedy brothers in two books: his biography of FBI Director J. Edgar Hoover, entitled Official and Confidential: The Secret Life of J. Edgar Hoover (1993), and his biography of Monroe, entitled Goddess (1985). In the Hoover book, Summers concludes that Monroe was in love with President Kennedy and wanted to marry him; she called the White House frequently in 1962; and that, when the married president ended their affair, Monroe became even more depressed, and turned to Robert Kennedy, who reportedly visited Monroe in Los Angeles the day that she died.
Patricia Seaton Lawford, the fourth wife of actor Peter Lawford, also deals with the Monroe-Kennedy matters in her biography of Peter Lawford, entitled The Peter Lawford Story (1988). Lawford’s first wife was Patricia Kennedy Lawford, a sister of John and Robert; Lawford was very close to the Kennedy family for over a decade, including the time of Monroe’s death. In 1997, documents purporting to prove a coverup of a relationship between JFK and Monroe were discovered to be fraudulent.
