Adolf Hölzel worked in Dachau from 1888 to 1905 , where he was founding the “Dachauer Malerakademie”. Already during his time in Dachau his work began moving toward abstraction, reflecting his interest in such principles as the golden section and Goethe’s Theory of Colors. He taught at the Stuttgart Academy, and painted—four years before Wassily Kandinsky—an abstract painting (Composition in Red, 1905). Among his students the so-called “Hölzel circle” developed, including Oskar Schlemmer, Willi Baumeister, Max Ackermann and Johannes Itten. (wikipedia: http://en.wikipedia.org/wiki/Adolf_Hölzel). Adolf Hölzel was not only member of the Munic Secession, he also was one of the founders of the Secession in Vienna.
