Wilson Markle

Wilson Markle (September 2, 1938 – July 25, 2020) 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.
