William Kurtz (1833 – December 5, 1904) was a German-American artist, illustrator, and photographer. He was also a pioneer in the development of halftone printing of color photographs.
Born in Hesse, Germany, he was apprenticed to a lithographer in Offenbach am Main at a young age and showed considerable artistic talent, taking first place in exhibitions while attending an art school there. However, after his two years of compulsory military service, he found he had lost his apprenticeship and moved to England to try his luck. Unable to find work there, he joined the British German Legion and went to fight in the Crimean War.
