Born June 19, 1934 in Aachen. In 1954, he began studying metallurgy, before dropping out four years later to work full-time as a photographer. He purchased his first Leica in 1952. Numerous awards and publications led quickly to success. Baumann travelled extensively and experimented in depth with the possibilities of colour photography. When he passed away on May 24, 2019, in Düsseldorf, he had been largely forgotten. His daughter transferred his estate (ca. 3,500 black and white and ca. 750 colour photographs, countless slides and numerous documents, magazines and books) to be handled by the ZEPHYR – Raum für Fotografie at the Reiss-Engelhorn Museums in Mannheim.
