Monroe married Jimmy Dougherty, in 1942. When he left to the South Pacific to fight in the Second world War, she joined a local munitions factory in Burbank, California. It was here that Marilyn got her first big break. Photographer David Conover, was covering the munitions factory to show women at work. He was struck by the beauty and photogenic nature of Norma, and he used her in many of her shots.
