As a model, Monroe occasionally used the name Jean Norman. She straightened her curly brunette hair and dyed it blonde to make herself more employable. Her figure was deemed more suitable for pin-up than fashion modeling, and she was featured mostly in advertisements and men's magazines. According to Emmeline Snively, the agency's owner, Monroe was one of its most ambitious and hard-working models; by early 1946, she had appeared on 33 magazine covers for publications such as Pageant, U.S. Camera, Laff, and Peek.

Through Snively, Monroe signed a contract with an acting agency in June 1946. After an unsuccessful interview at Paramount Pictures, she was given a screen-test by Ben Lyon, a 20th Century-Fox executive. Head executive Darryl F. Zanuck was unenthusiastic about it, but he gave her a standard six-month contract to avoid her being signed by rival studio RKO Pictures. Monroe's contract began in August 1946, and she and Lyon selected the stage name "Marilyn Monroe". The first name was picked by Lyon, who was reminded of Broadway star Marilyn Miller; the last was Monroe's mother's maiden name. In September 1946, she divorced Dougherty, who was against her having a career.
