Hermann Finsterlin (18 August 1887 – 16 September 1973) was a German visionary architect, painter, poet, essayist, toymaker and composer.
He played an influential role in the German expressionist architecture movement of the early 20th century but due to the harsh economic climate realised none of his projects.
He originally studied medicine, physics and chemistry, and then later, philosophy and painting in Munich.
In 1919 he assisted Walter Gropius in organising the "Exhibition for Unknown architects" for the Arbeitsrat für Kunst and contributed to Bruno Taut's Glass Chain letters under the pseudonym Prometh.
"[1] Under the Nazi regime in the 1930s, Finsterlin was commissioned to produce official portraits and frescoes in state buildings "through a misunderstanding...." Finsterlin dodged the responsibility through feigned illness as long as he could, and supplied his art to the Nazis only under threat of concentration camp incarceration.
