Hein Gravenhorst

Hein Gravenhorst is a German artist and photographer recognized as a pioneer of generative photography. He studied photography, graphic design and film technology in Berlin and Munich, and in 1970 was appointed as a photography lecturer at the Kiel University of Applied Sciences. Gravenhorst's early work, shapedby the emergence of computer technology in the 1960s, explores the aesthetic and technical possibilities of computers.

In 1968, Gravenhorst participated in the landmark Generative Photography exhibition at the Bielefelder Kunsthaus, helping define the genre alongside fellow pioneers such as Gottfried Jäger. Since 2001, Gravenhorst has extended his practice into digital media, creating works he describes as "energy fields" that evoke spiritual communication with the viewer.

His works are held in major public collections, including the Museum of Modern Art in New York and the Peter C. Ruppert Collection.
