"Heinrich Kuehn and His American Circle: Alfred Stieglitz and Edward Steichen"

Though not as well known as either of the Americans mentioned in the show's title, the Austrian Kuehn (1866–1944) was an influential figure in the development of fine-art photography. He was one of the medium's first experimenters with early color-film technologies like Autochrome, which gave his pictorialist landscapes and portraiture a particularly haunting, evanescent quality.
