Rudolf Kicken, the founder of one of the oldest photo galleries in Germany and one of one of its biggest art dealers, died last week at the age of 67. In 1979, Kicken opened a gallery in Cologne which bore his name. It quickly became the Mecca of German photography. With his wife, Annette, Kicken specialized in 20th-century avant-garde German and Czech photography, including the Bauhaus school, and masters like Man Ray, Moholy-Nagy and Rodchenko. He later took an interest in Newton, Umbo, Ed Van der Elsken, Heinrich Kühn and Rudolf Koppitz.
