Besides introducing him to Eva Braun, Hoffmann also introduced Hitler to art dealer Maria Almas Dietrich, who used that connection to sell hundreds of paintings to Hitler himself, for the collection of Hitler's planned "Führermuseum" in his hometown of Linz, Austria, as well as to other high-ranking Nazis, and to various German museums. In 1941, Hoffmann was chief among the many Nazi chieftains who took advantage of the occupation of the Netherlands to buy paintings and other artworks from Dutch dealers, sometimes at inflated prices. That drove the art market up, much to the consternation of Hans Posse, who had been commissioned by Hitler to assemble a collection for the planned museum. Posse appealed to Hitler to put a stop to it, but Hitler refused the request.
