For about 10 years Tim Otto Roth has worked on the photogram and belongs now to the few leading adepts of that medial outlaw. He studied among others with Floris M. Neusüss, whose anthological work he continues in the new form of the portal www.photogram.org. The English portal with database entries to about 300 photogram artists advanced to one of the most important information sources in that field. After his art studies Roth also received with a theoretical scholarly piece on the photogram a final degree in the Theory of Visual Communication. In 2001/02 he was guest lecturer in Madrid und Valencia (E). 2004/05 he gave courses and lectures at the Kunsthochschule Kassel. Together with Peter Weibel he was chairman of the symposium The Photogram. Light, Trace and Shadow at the Center for Arts and Media ZKM Karlsruhe (D) in 2006. He curated in 2007 the photogram film program in the context of the photogram exhibition kamera_los at the Museum der Modern in Salzburg (A). In his publications he opens up new photogrammatical terrain. His recent articles dealt with the photogram film and the history of the full body photogram.
