Roger Schall was a photographer during the interwar period, a contemporary of Brassaï. He excelled in photojournalism, in which he was one of the pioneers, as well as in the photographic disciplines of fashion and portraits. In the early 30s, the "revolution" Leica and Rolleiflex allowed him to fulfill his passion for images taken on the spot. Paris was his main exploration ground, where the night allowed him to capture and expose with strength and delicacy the particular shapes of a city made of diversities.
