KOKO THE CLOWN
Koko the Clown is an animated cartoon character created by Max Fleischer in the 1920s. The character originated when Max Fleischer invented the Rotoscope, a device that allowed for animation to be more lifelike by tracing motion picture footage of human movement. Fleischer filmed his brother Dave in a clown costume, and after tracing the film footage (amounting to some 2,500 drawings and a year's work), the character that would eventually become Koko the Clown was born, although he did not have a name until 1924.
