Wilson Markle
Wilson Markle was a Canadian engineer who invented the film colorization process in 1970. His first company, Image Transform, colored pictures from the Apollo space program to make a full-color television presentation for NASA.
His method used computers to assign predetermined colors to shades of gray in each scene.
In 1983, he founded Colorization Inc., which was co-owned by Hal Roach Studios and International HRS Industries. The word "colorization" later became a generic name.
