She captured her first crown in 1949 when she won Mobile's "Miss Torch" pageant. In 1950, Fox entered Miss Alabama for the scholarship opportunities the pageant presented. As Miss Alabama, she traveled to Atlantic City, New Jersey, to compete in the Miss America 1951 pageant. Having been educated in a convent school, she was reluctant to pose in a swimsuit and refused to do so after she won Miss America. That led the swimsuit company, Catalina, to withdraw their sponsorship of the Miss America pageant and eventually brought about the creation of the rival Miss USA pageant. Fox's Miss America title, although won in 1950, was for 1951 and is the first Miss America title to be "postdated" in this manner. Due to the change, there was no Miss America 1950. The Miss America Organization has claimed that Fox's actions were pivotal in directing pageant progress towards recognizing intellect, values, and leadership abilities, rather than focusing on beauty alone. From then on the Miss America pageant concentrated more on scholarship than beauty. Fox was active in the feminist movement. After her one-year reign as Miss America; was active in the NAACP, CORE, and SANE ; and studied philosophy at the New School for Social Research in New York City. Fox was an opera singer and did gain a reputation in that area. She continued to sing, appearing with the Mobile Opera Guild, and helped found an off-Broadway theater.
