Expressionism is a form of art based on distorted forms and bold colors used to express emotion. Expressionist artists believed that art should convey feelings rather than the real world. A famous expressionist was Norwegian artist, Edvard Munich. His painting entitled Scream is a well-known work of art. Other well known expressionists were Kollwitz, Kirchner, Nolde, Franz Marc, Wassily Kandinsky, Paul Klee and Gunther Gerzso.
Expressionism, as it was generally known, developed almost simultaneously in different countries from about 1905. Characterized by heightened, symbolic colors and exaggerated imagery, it was German Expressionism in particular that tended to dwell on the darker, sinister aspects of the human psyche.
