Photography career During the 1940s, Arbus became a photographer for the United States Army. In 1946, after he completed his military service, he and his first wife, photographer Diane Arbus (née Nemerov, whom he had married in 1941), started a photographic advertising business in Manhattan. Arbus was primarily known for advertising photography that appeared in Glamour, Seventeen, Vogue, Harper's Bazaar, and other magazines, as well as the weekly newspaper advertising photography for Russeks, a Fifth Avenue department store owned by Diane's father.
