Louis Raemaekers (born April 6, 1869, Roermond, Neth.—died July 26, 1956, Scheveningen) was a Dutch cartoonist who gained international fame with his anti-German cartoons during World War I.
Raemaekers at first painted landscapes and portraits. His first political cartoons appeared in 1907, and he joined Amsterdam’s Telegraaf in 1909. The sincerity and vigour of his wartime cartoons roused enthusiasm in England, France, and the United States, and after 1916 he lived for some years in England to supply the Allied press more easily. He was also a cartoonist during World War II.
