Norma Jeane Mortenson, Before She Became Marilyn Monroe

Marilyn Monroe's first movie role was an uncredited role as a telephone operator in The Shocking Miss Pilgrim in 1947. She won a brief role that same year in Dangerous Years and extra appearances in Green Grass of Wyoming and You Were Meant for Me, she also won a three scene role as Betty in Scudda Hoo! Scudda Hay!. Monroe's part in Scudda Hoo! Scudda Hay! was to be three scenes long, but before the release of the film her part was cut down to a brief one-line scene. Green Grass of Wyoming, You Were Meant For Me, and Scudda Hoo! Scudda Hay!, wouldn't be released until 1948, which was months after Monroe's contract had ended in late 1947. She attempted to find opportunities for film work, and while unemployed, she posed for nude photographs. She was paid $50 and signed the model release form as "Mona Monroe". It would be the only time she would get paid for the nude photos. That year, she was also crowned the first "Miss California Artichoke Queen" at the annual artichoke festival in Castroville.
In 1948, Monroe signed a six-month contract with Columbia Pictures and was introduced to the studio's head drama coach Natasha Lytess, who became her acting coach for several years. She starred in the low-budget musical Ladies of the Chorus. Monroe was capitalized as one of the film's bright spots, but the movie didn't bring any success for Columbia or for Marilyn. During her short stint at Columbia, studio head Harry Cohn softened her appearance somewhat by correcting a slight overbite she had.
She had a small role in the Marx Brothers film Love Happy (1949). She impressed the producers, who sent her to New York to feature in the film's promotional campaign. Love Happy brought Monroe to the attention of the talent agent, Johnny Hyde, who agreed to represent her. He arranged for her to audition for John Huston, who cast her in the drama The Asphalt Jungle as the young mistress of an aging criminal. Her performance brought strong reviews, and was seen by the writer and director, Joseph Mankiewicz. He accepted Hyde's suggestion of Monroe for a small comedic role in All About Eve as Miss Caswell, an aspiring actress, described by another character as a student of "The Copacabana School of Dramatic Art". Mankiewicz later commented that he had seen an innocence in her that he found appealing, and that this had confirmed his belief in her suitability for the role. Following Monroe's success in these roles, Hyde negotiated a seven-year contract for her with 20th Century Fox, shortly before his death in December 1950. It was at some time during this 1949–50 period that Hyde arranged for her to have a slight bump of cartilage removed from her somewhat bulbous nose which further softened her appearance and accounts for the slight variation in look she had in films after 1950.
Monroe enrolled at UCLA in 1951 where she studied literature and art appreciation, and appeared in several minor films playing opposite such long-established performers as Mickey Rooney, Constance Bennett, June Allyson, Dick Powell and Claudette Colbert. In March 1951, she appeared as a presenter at the 23rd Academy Awards ceremony. In 1952, Monroe appeared on the cover of Look magazine wearing a Georgia Tech sweater as part of an article celebrating female enrollment to the school's main campus. In the early 1950s, Monroe and Gregg Palmer both unsuccessfully auditioned for roles as Daisy Mae and Abner in a proposed Li'l Abner television series based on the Al Capp comic strip, but the effort never materialized.
