Marilyn Monroe: Monroe crammed a lot of living into her 36 yearsthree husbands, countless affairs, a name change and 30 filmsall while grappling with depression and a self-destructive streak. She became seriously dependent on drugs and alcohol in her 30s, and was fired from the film Somethings Got to Give due to chronic lateness. Four months later her housekeeper found her dead in her Brentwood home of a drug overdose that later was ruled suicide. (Matty Zimmerman / AP)
