"John Heartfield (born Helmut Herzfeld; 19 June 1891 – 26 April 1968) was an artist. He was a pioneer in the use of art as a political weapon.

Heartfield also created book jackets for authors such as Upton Sinclair, as well as stage sets for such noted playwrights as Bertolt Brecht and Erwin Piscator." Read on at en.wikipedia.org
