Charles William Kahles (January 12, 1878, January 21, 1931) was a prolific German-born American cartoonist responsible for numerous comic strips, notably Hairbreadth Harry. He is credited as the pioneer of daily comic strip continuity with his Clarence the Cop, which he drew for the New York World in 1900 to 09, introducing to newspapers the innovation of continuing a comic strip story in a day-to-day serial format. The cartoonist and comics historian Ernest McGee called Kahles the "hardest working cartoonist in history, having as many as eight Sunday comics running at one time (1905-06) with no assistants to help him." Between 1898 and 1931, Kahles drew a total of 25 comic strips, in addition to paintings, book illustrations and advertisements.
