Preston Mitchell Fleet (February 26, 1934 – January 31, 1995), nicknamed Sandy, was the founder of Fotomat.
Fotomat was a once-widespread retail chain of photo development drive-thru kiosks located in shopping center parking lots.
Fotomats were distinctive for their pyramid-shaped gold-colored roofs and signs with red-lettering, usually positioned in a large parking area, such as a supermarket or strip mall, as the Fotomat huts required a minimal amount of land and were able to accommodate cars driving up to drop off or pick up film.
He helped design the Science Center to have a special movie projector, Omnimax, housed in a dome wall and ceiling that makes the audience feel as if they are moving like the camera did when filming.
A decade earlier he had been a founding director of the San Diego Air and Space Museum.
