New to the website: John Walker III, an American art curator, and the second director of the National Gallery of Art, from 1956 to 1969. Walker, pictured here on the steps of the National Gallery, was one of several museum directors who were photographed for a project created by Ivan Dmitri called “Photography in the Fine Arts.” You can see their Sitting info here.

Ivan Dmitri, a photographer himself, helped to gain acceptance for photography as an art medium, and established one of the first photography exhibits at New York’s Metropolitan Museum of Art.
