Max Beckmann was one of the leading German Expressionist
painters. He met Munch in 1906, exhibited with Dix and Grosz and other
Neue Sachlichkeit painters and taught in Frankfurt until 1933, when he
was dismissed as 'decadent'. Just before the opening of the Nazi-sponsored
Degenerate Art exhibition in 1937 he emigrated to Holland, moving to America
in 1947, where he died. His nine Triptychs, painted from 1932 onwards, show
that the main influences on him were Bosch and the German primitives, apart
from his own contemporaries.
He is represented in American museums (e.g.
Harvard Univ.), and now in Germany as well. There is a work in London
(Tate).
