Did You Know...
...that two musicians were responsible for the invention of color print film? Fascinated by photography, Leopold Godowsky and Leopold Mannes worked together to produce an easy-to-use, practical color film. They worked full time as music teachers and gave concerts while experimenting during their off hours in Mannes' kitchen. Their success earned them full-time, well-paying jobs at Kodak and their efforts resulted in Kodachrome film, which was introduced in 1935.
