A Birthday Salute to Max Fleischer (July 19, 1883 – September 11, 1972), pioneer in the development of the animated cartoon. As the head of Fleischer Studios, he brought such characters as Betty Boop, Koko the Clown, Popeye, and Superman to the movie screen.

Max Fleischer was responsible for a number of technological innovations.

• "Fleischer came up with a concept to simplify the process of animating movement by tracing frames of live action film. His patent for the Rotoscope was granted in 1915, although Max and his brother Dave Fleischer made their first cartoon using the device in 1914. Extensive use of this technique was made in Fleischer's Out of the Inkwell series for the first five years of the series, which started in 1919 and starred Koko the Clown and Fitz the dog." direct quote source (1)
