John Heartfield

John Heartfield (born Helmut Herzfeld; 19 June 1891 – 26 April 1968) was a 20th-century German visual artist who pioneered the use of art as a political weapon. Some of his most famous photomontages were anti-Nazi and anti-fascist statements. Heartfield also created book jackets for book authors, such as Upton Sinclair, as well as stage sets for contemporary playwrights, such as Bertolt Brecht and Erwin Piscator. Provided by Wikipedia
