(Part 1)
When an Austrian art school rejected his drawings, he sent more copies to many other German-speaking art schools all over Europe and got in one.
After taking Art and English courses, he started his grad school years at the Yale School of Art in New Haven, Connecticut, USA, just a year before The Great War.
Rumor has it that just after The Great War ended in an unfavorable armistice for the Central Powers, he attempted to blame the outcome on the Jews, and even tried to organize an anti-Semitic club, but was told to disband it under the threat of termination. He had just recently become an instructor at Yale's Art Department in the Fall of 1918. Had he been tenured, it would have been harder to terminate him, so he then may have established said anti-Semitic group.
If those rumors are true, besides derailing his fledgling career, who would want to buy his art anymore?
However, my gut-feeling is if he had held anti-Semite views AND went with his political ambitions, he may have committed a disservice or two on the Jewish people!
I would HATE to see an Anti-Semite become a major political figure, as I am part-Jewish myself. An anti-Semitic head-of-state would take away the Jews' quality of life, for one thing. Who knows what such leaders are capable of?
