"Louis Raemaekers (1869-1956) was one of the most famous cartoonist/caricaturists of WWI. He crossed the border from Holland into Belgium to witness first-hand the atrocities of the advancing German army. He subsequently chronicled the brutality of theses forces in his cartoons which drew the wrath of the Germans. They forced the Dutch authorities to put the illustrator on trial for jeopardising the neutrality of the Netherlands (acquitted). A reward was offered by the Germans for Raemaekers’ arrest and he escaped to Britain where he continued to skewer the German army in his drawings. He produced a thousand cartoons during the war and gained world wide acclaim from their syndication.
