SIEMENSSTERN TABLEAU BLACK is an artwork created in 1966 by Hein Gravenhorst, a photographer known for his involvement in Generative Photography. In 1968, Gravenhorst participated in an exhibition at the Bielefelder Kunsthaus alongside Gottfried Jäger, Pierre Cordier, and Kilian Breier, where Generative Photography was not only the title but also defined the program of the exhibition. 

Generative Photography aimed to create aesthetic structures based on defined programs using photochemical, photo-optical, or photo-technical operations. The goal was to achieve optional and functional references within the construction of the aesthetic structure. This genre of photography was influenced by Max Bense's Generative Aesthetic, which provided principles for generating specific operations methodically. 

Gravenhorst's works from 1965 to 1972 are highly regarded, and this particular artwork, SIEMENSSTERN TABLEAU BLACK, is part of his impressive oeuvre. The artwork features the Siemens Star, a geometric pattern generated through the combined rotation-translation number system of 1, 2, 4, 8, and 16. It is presented on silver gelatin paper, measuring 59.5 x 49.5 cm. The artwork is in good condition and is a unique piece. 

Hein Gravenhorst's works have been acquired by international private and public collections, including the Collection Peter C. Ruppert in Würzburg and the Museum of Modern Art (MoMA) in New York. In addition to his artistic career, Gravenhorst has also pursued alternative medicine as a therapist since the mid-1970s. He currently resides and works in Berlin. 

The artwork is hand-signed by the artist and dated on the reverse side with a pencil, adding to its authenticity and provenance.
