Traumatized by his military service in WW1, Beckmann used his art to show Europe’s military madness. His intense imagery brought renown as one of Weimar Germany’s greatest artists until Hitler’s regime deemed him a ‘degenerate’. Emigrating to the US after WW2 he found New York much to his taste, enjoyed a burst of creativity but died within a year of arrival. A useful background piece is here and more images here.
