Why was Oskar Kokoschka dismissed from his teaching position in Vienna?

Oskar Kokoschka was dismissed from his teaching position at the School of Arts and Crafts in Vienna after the public reaction to his plays caused a significant scandal.1

These early works, which helped pioneer Expressionist theatre, were deeply tied to his humanist philosophy and his sensitivity to the moral crises of modern life. While his artistic focus was often on the human figure and the expression of psychological states, the controversial nature of his writing led to his removal from the faculty.21
