Rudolf Koppitz (1884 - 1936) was an Austrian pictorial photographer.
Koppitz's work is marked by a pronounced awareness of form, line, and the surface play of light and shadow. Early in his career, Koppitz was known for staging groups of subjects in the style of the Vienna Secession, the most well known example of this being his Bewegungsstudie, "Motion Study".
Bewegungsstudie's languid nude, elaborately robed women and undeniable sensuality, in the context of its rigorous and artistic composition, bring to mind the sexual morbidity of Viennese artists like Gustav Klimt and Alphonse Mucha, as well as the Swiss symbolist painter Ferdinand Hodler and has made it as unforgettable then as it is today. It has become the Koppitz's signature image, and was also his best-seller. Prints of the image were purchased by, among others, the Toledo Museum of Art; the New York Camera Club notable Joseph Bing, head of that club's print committee; and the Englishman Stephen Tyng, who published it in a small portfolio of works from his collection.
Over the course of 30 years of work, Koppitz's photography came full circle returning in his later years to where he started, working with a renewed focus on nature and documenting the lives and condition of rural peasants. Koppitz is perceived by some as a progressive modern artist while on the other hand he was one of the more conservative photographers in his time, holding true to a number of traditions and always telling a story with his photographs.
