Edwin H. Land

Edwin Herbert Land, ForMemRS, FRPS, Hon.MRI (May 7, 1909 – March 1, 1991) was an American scientist and inventor, best known as the co-founder of the Polaroid Corporation. He invented inexpensive filters for polarizing light, a practical system of in-camera instant photography, and the retinex theory of color vision. His Polaroid instant camera went on sale in 1948 and made it possible for a picture to be taken and developed in one minute or less. Land received the Presidential Medal of Freedom in 1963, the IRI Medal in 1965, the Perkin Medal in 1974, the Harold Pender Award in 1979, and the National Medal of Technology in 1988. He was also renowned outside of his home country, being a member of England's Royal Photographic Society, Royal Institution, and Royal Society (receiving Fellowship of the latter).
