While her husband was in the Merchant Marine during World WarII, Norma JeaneDougherty moved in with her mother-in-law, and started to work in the Radioplane Company factory (owned by HollywoodactorReginald Denny), spraying airplane parts with fire retardant and inspecting parachutes. Army photographer DavidConover was scouting local factories, taking photos for a YANK magazine article about women contributing to the war effort. He saw her potential as a model and She was soon signed by The Blue Book modeling agency. In his book Finding Marilyn, Conover claimed the two had an affair that lasted years. Shortly after signing with the agency, Monroe had her hair cut, straightened, and lightened to goldenblonde.
She became one of Blue Book's most successful models, appearing on dozens of magazine covers. In 1946, she came to the attention of talent scout Ben Lyon. He arranged a screen test for her with 20th CenturyFox. She was offered a standard six-month contract with a starting salary of $125 per week.
Monroe proved She could carry a big-budget film when she starred in Niagara in 1953. Movie critics focused on Monroe's connection with the camera as much as on the sinister plot. She played an unbalanced woman planning to murder her husband.
Around this time, nude photos of Monroe began to surface, taken by photographer Tom Kelley when She had been struggling for work. Prints were bought by Hugh Hefner and, in December 1953, appeared in the first edition of Playboy. To the dismay of Fox, Monroe decided to publicly admit it was indeed her in the pictures. When a journalist asked her what She wore in bed she replied, "Chanel no.5". When asked what she had on during the photo shoot, she replied, "The radio".
Over the following months, Gentlemen Prefer Blondes and How to Marry a Millionaire cemented Monroe's status as an A-list actress and She became one of the world's biggest movie stars. The lavish Technicolor comedy films established Monroe's "dumb blonde" on-screen persona.
