Edwin Herbert Land was a American scientist, inventor, and industrialist. While studying physics at Harvard in the 1920s he became interested in the polarization of light. He developed a new polarizing material, which he called Polaroid, and in 1937 formed the Polaroid Corporation with himself as president and head of research.

Land is best known for the invention of the Polaroid instant photographic process, in which processing chemicals are incorporated in the photographic material and processing occurs immediately after picture taking, using a special camera. Land involved the Eastman Kodak Company in the production of Polaroid type 40 film that was introduced in 1948. It was a ‘peel-apart’ system that gave sepia-coloured prints. The Polacolor process, which gave a full colour print in 60 seconds, was introduced in 1963 and the SX-70 system, which was integral and did not require peeling apart, was introduced in 1972....
