A carousel slide projector is a common form of slide projector, used to project slide photographs and to create slideshows. It was first patented on May 11, 1965, by David E. Hansen of Fairport, NY. Hansen was an engineer at the Eastman Kodak Company. The original Carousel S Slide Projector was invented by Italian-American Louis Misuraca, who brought his design to the Kodak company, selling it for a lump sum. The design was refined by Hans Gugelot and Reinhold Hacker for Kodak AG in Stuttgart in 1963, and is part of the permanent collection at MOMA, New York
