The colour motion picture process, Technicolor™ was discovered in 1917 by Herbert Thomas Kkalmus, an MIT
graduate who came to Queen's in 1910 as Assistant Professor of Physics in the then-School of Mining. The discovery's success was assured in 1938-39 when it was adopted by Walt Disney and MGM studios.
Technicolor™ was the mainstay of the global film industry and was the most widely used colour process in Hollywood for nearly 50 years before being overtaken by competing technologies. Kalmus has a star on the Walk of Fame in Hollywood, California.
