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. « AE Books - Rare Books, Book Auctions, Antiquarian Book Collecting"/>
