At the age of 25, Parks was struck by photographs of migrant workers in a magazine. He bought his first camera, a Voigtländer Brillant, for $7.50 at a Seattle, Washington, pawnshop and taught himself how to take photos. The photography clerks who developed Parks's first roll of film applauded his work and prompted him to seek a fashion assignment at a women's clothing store in St. Paul, Minnesota, owned by Frank Murphy. Those photographs caught the eye of Marva Louis, wife of heavyweight boxing champion Joe Louis. She encouraged Parks and his wife, Sally Alvis, to move to Chicago in 1940, where he began a portrait business and specialized in photographs of society women. Parks's photographic work in Chicago, especially in capturing the myriad experiences of African Americans across the city, led him to receive the Julius Rosenwald Fellowship, in 1942, paying him $200 a month and offering him his choice of employer, which, in turn, contributed to being asked to join the Farm Security Administration, which was chronicling the nation's social conditions, under the auspice of Roy Stryker.
