Erich Maria Remarque was a German-born novelist. His landmark novel All Quiet on the Western Front (1928), based on his experience in the Imperial German Army during World War I, was an international bestseller which created a new literary genre, and was adapted to film several times. Remarque's anti-war themes led to his condemnation by Nazi propaganda minister Joseph Goebbels as "unpatriotic". He was able to use his literary success to relocate to Switzerland and the United States, where he became a naturalized citizen.
