Günter OsterlohGünter Osterloh worked for Ernst Leitz Wetzlar GmbH as of 1963. In 1976 he changed to the photo marketing department, dealing with the Leica M and R systems. During the process when the Leitz photo sector evolved into the independent Leica GmbH in Solms – today Leica Camera AG in Wetzlar – , Osterloh took care of the new company's product management. In 1993, he took over the management of the Leica Academy. In this new position, his interest was especially focused on the possibilities of photographic art work.
After retiring in 2002, Osterloh took on a teaching assignment at the Justus-Liebig University in Gießen, and for ten years ran Photos for the Press seminars in the Journalistic History division at the Historischen Institut. Osterloh has published award-winning books on the Leica M and R systems, that were also translated into English, Italian and Chinese. He is currently working on a history of Leitz and the story of the Leica.
