Land Invents a Camera/Film System That Develops Instant Pictures (Great Events from History II: Science and Technology Series)
Article abstract: Land and coworkers invented a camera and a photographic process that produced a finished positive print directly from the camera immediately after exposure.
Summary of Event
As a chemist and physicist primarily interested in research relating to light and vision, and materials that affect them, Edwin Herbert Land’s first major scientific discovery was a commercially practical, synthetic, light-polarizing material in sheet form. In order to exploit this discovery, Land founded the Polaroid Corporation in 1929. It was at Polaroid that Land became inevitably drawn into the field of photography.
During the summer of 1943, while Land and his wife were vacationing in Santa Fe, New Mexico, with their three-year-old daughter, Land stopped to take a picture of the child. After the picture was taken, his daughter asked to see it. When she was told that she could not see the picture immediately, she asked how long she would have to wait. Within an hour after his daughter’s question, Land had conceived a preliminary plan for design of the camera, the film, and the physical chemistry of the instant camera. With great excitement, he rushed to a friend’s house and described in detail a dry camera that would produce a picture immediately after exposure. In the standard photographic process, film must be developed, rinsed, fixed, washed, and dried; then the resulting negative must be printed on the...
