# Nikolai Konstantinov

Russia (Then: Soviet Union)

In 1968 a group of Soviet physicists and mathematicians with N.Konstantinov as its head created a mathematical model for the motion of a cat. On a BESM-4 computer, they devised a program for solving the ordinary differential equations for this model. The Computer printed hundreds of frames on paper using alphabet symbols that were later filmed in sequence thus creating the first computer animation of a character, a walking cat.
