Famous for playing comic "blonde bombshell" characters, Monroe became one of the most popular sex symbols of the 1950s and was emblematic of the era's attitudes towards sexuality.
She dedicated 1955 to building her company and began studying method acting at the Actors Studio.
She drew attention with her costume: a beige, skintight dress covered in rhinestones, which made her appear nude.
On June 7, Fox fired Monroe and sued her for $750,000 in damages.
She and photographer Bert Stern collaborated for two series of photographs, one a standard fashion editorial and another of her posing nude.
At 4:25 a.m., they notified the Los Angeles Police Department.
Marilyn Monroe was later entombed at crypt No. 24 at the Corridor of Memories.
