Walter Trier was born in Prague in 1880. In 1910 he moved to Berlin, where he would later be introduced to Kastner, and began his career drawing cartoons for the Berliner Illustrated. He also contributed to the satirical weekly Simplicissimus, where during the 1920s, despite great personal risk, he ridiculed Hitler and the Nazi Party in a series of cartoons. In 1936 he fled to London, where he was involved in producing anti-Nazi leaflets and political propaganda drawings. He would go on to have a rich career, producing around 150 covers for the humorous magazine Lilliput. He died in 1951 in Ontario, Canada.
