Lyonel Feininger (1871-1956) was 58 years old when he took up photography. He had been a professor at the Bauhaus for almost a decade, and had enjoyed widespread success as a comic artist and painter. Ever open to new pursuits, and inspired by the works of his photographer sons Lux and Andreas and the experimental photography of his Dessau neighbor L szl Moholy-Nagy, Feininger took up the camera in 1928 and began to explore a variety of avant-garde techniques. This painter of crystalline architectures and landscapes left a legacy of fascinating unsettling images of shop window mannequins and reflections, nocturnal photographs using double exposures and other works. This is the first publication devoted to this little-known body of work. Examining about 70 original prints, it also relates Feininger's photography to the rest of his extensive oeuvre.
