Word History

Etymology

verbal derivative of rotoscope "device for projecting a single frame of film onto a glass drawing board from which an image on the film can be traced," probably from rot(ate) entry 2 or + rot(ary) entry 1 + -o- + -scope

Note: The device was developed by the American animator Max Fleischer (1883-1972). The patent awarded to Fleischer, for a "method of producing moving-picture cartoons" (applied for December 6, 1915, granted October 9, 1917), does not use the word rotoscope.
