Hans von Hayek (19 December 1869, Vienna - 17 January 1940, Munich) was an Austrian-born German Impressionist painter.
In 1891, after a short period of study at the University of Applied Arts in Vienna, he moved to Munich and enrolled at the Academy of Fine Arts, where he studied with Gabriel von Hackl, Wilhelm von Lindenschmit and Carl von Marr. Later, he met the animal painter, Heinrich von Zügel, who ultimately had the most influence on his style.
After leaving Munich, he stayed in Olching for a time then, in 1900, settled at the artists' colony in Dachau. There, he started a private school devoted to plein aire painting, which he operated until 1915. Many notable painters studied there, including Hugo Hatzler , Hermann Stenner, Anna Klein and Norbertine Bresslern-Roth . One of his students, Carl Thiemann, wrote in his memoirs that the local farmers frequently complained about them trampling the grass and leaving oil paints behind.
The financial success of his school enabled him to make frequent study trips throughout Western and Northern Europe. As a member of the board of the Munich Secession, he helped organize their 1904 exhibition at the Staatliche Antikensammlungen. He also exhibited with the Deutscher Künstlerbund and, in 1908, became a German citizen.
