Heinrich Thannhauser (born February 16, 1859, in Hürben, today a district of Krumbach (Swabia); died 1934 on the German-Swiss border) was a German gallery owner and art collector. As an art dealer, he was one of the most important promoters of early Expressionist art in Germany.
The Jewish Thannhauser family came from Mönchsdeggingen. Heinrich Thannhauser first learned the profession of a tailor. He founded his Munich Modern Gallery (Moderne Galerie)in 1904.[1] At first he exhibited the artworks of French Impressionists such as Édouard Manet, Edgar Degas and Paul Gauguin. Later works by Pablo Picasso and Georges Braque were added.
In 1909, Thannhauser separated from his partner Franz Josef Brakl and continued to run the gallery under the name Galerie Thannhauser.[2] The first exhibition of the Neue Künstlervereinigung München took place in the Arco-Palais in the same year. In 1911 he began collaborating with Der Blaue Reiter.[3] In 1918 he had himself painted in Berlin simultaneously by Lovis Corinth and by Max Liebermann; the one he sat for a portrait in the morning, the other in the afternoon.
In 1920 his nephew Siegfried Rosengart opened a branch of the gallery in Lucerne.[4]
In 1934 in attempting to flee from the Nazis to Switzerland, Thannhauser died of a stroke at the border.
His son Justin Thannhauser, who was also an art dealer, established branches in Lucerne (1919) and Berlin (1927). The parent company in the Arco-Palais, Theatinerstraße 7 in Munich, was dissolved in 1928.
In 1937, the National Socialists confiscated the holdings. Justin Thannhauser emigrated to Paris, where he ran a gallery until 1941. Its inventory of artworks was confiscated during the Nazi occupation of Paris. Justin Thannhauser managed to escape to New York, where he continued to deal in art. In 1963 Justin Thannhauser donated his private collection as well as that of his father, Heinrich, to the Guggenheim Museum, New York, where a room commemorates him.[5]
Heinrich Thannhauser's daughter, Trude Thannhauser Beyer, also collected art.[6]
