The story
Founding
The firm's establishment as the Versatz- und Fragamt zu Wien was carried out by Emperor Joseph I in 1707. Seventy years later it moved into the former Dorotheerkloster, which gave it its current name of Dorotheum. The new building of the Dorotheum Palace in the location of the old cloister was completed in 1901.
Nazi-era activities
During the Nazi years, the Dorotheum played an important role in selling property seized from Jews by the Gestapo Office for the Disposal of the Property of Jewish Emigrants, known as the Vugesta.The Dorotheum chief expert, Dr. Hans Herbst, was appointed by Hermann Voss, director of Hitler's planned Führermuseum, as an official buyer for the Nazis.
Post-war redevelopment
After WWII the Dorotheum was rebuilt. In 1978 it held 2,722 auctions that grossed $25.2 million. At the end of the 1980s, the building's foyer and interior were redesigned by the Viennese architect and designer Luigi Blau. In 2001, the Dorotheum was sold to an Austrian consortium and since then has greatly expanded, including opening offices abroad in Germany, Belgium, Italy and the UK. In November 2018, a landscape painting, one of Pierre-Auguste Renoir's lesser-known works valued at €160,000, was stolen from the auction house just days before it was scheduled to be auctioned off.
