Source Title
Description The auction house of Ketterer Kunst (Ketterer Art) traces its roots to 1946 when Roman Norbert Ketterer conducted his first auction in Stuttgart, Germany. He was joined later that year by his brother, Wolfgang, just home from a prisoner of war camp. The brothers found that despite the tough post-war times, there was still a great interest in works of art, particularly more creative forms that had been considered "degenerate" by the Third Reich.

Roman Norbert Ketterer moved on to working for and writing about particular artists in 1954, while Wolfgang Ketterer set up his own gallery. In 1965, he moved it to Munich, where it is now located, and began conducting auctions again in 1968. Later, he expanded his auctions to cover books and manuscripts along with art. In 1989, the firm expanded to Hamburg by taking over the almost two century old house of F. Dorling, adopting the name "Ketterer Kunst" at the time. Today, auctions specific to books, manuscripts and related material can be found on its calendar as well as those for art.

Roman Norbert Ketterer died in 2002, while Wolfgang Ketterer died in 2009. However, Wolfgang's son Robert Ketterer had taken over management of the family firm from his father during the 1990s.
