Carl Hentschel (27 March 1864 – 9 January 1930) was a British artist, photographer, printmaker, inventor and businessperson. He developed techniques for printing illustrations, particularly the Hentschel Colourtype Process using three colours, which have been described as "revolutionising" newspaper illustration. He was the original of "Harris" in Jerome K. Jerome's Three Men in a Boat (1889).
