Oskar Reinhart was one of the most important art collectors and patrons in Switzerland: until his death in 1965, he acquired an impressive collection of paintings and sculptures – European masterpieces from the 15th to early 20th century, including works by Renoir, Cézanne, Delacroix and Cranach. Today, the most prestigious treasures of his collection can still be seen in his former mansion Am Römerholz in Winterthur. The second part of his collection is housed in a former Gymnasium in the city centre of Winterthur, mostly consisting of German, Austrian and Swiss masterpieces: the Museum Oskar Reinhart.
