Edwin Herbert Land (1909–91) was an American scientist, inventor, and entrepreneur best known for founding the Polaroid Corporation and creating instant photography.
Born in Bridgeport, Connecticut, Land studied physics at Harvard University but left before graduating to pursue his interest in light polarization. He revolutionized optics with the invention of the first synthetic polarizing filter, which led to Polaroid sunglasses and other optical devices. In 1947, he introduced the Polaroid instant camera, which allowed photographs to develop in minutes. His innovations culminated in the SX-70 (1972,) the first fully integrated instant camera.
Beyond photography, Land contributed to military technology, including aerial reconnaissance systems during World War II. His research into color vision led to the conclusion that the retina perceives color through the interplay of long and short wavelengths across a visual scene, not by detecting individual wavelengths. This theory impacted the fields of imaging and display technologies.
In 1963, he introduced Polacolor film, producing color photos in under a minute. In 1972, he followed this with fully automatic, pocket-sized cameras and film. His most influential publication, Retinex Theory of Color Vision (1959,) advanced the understanding of human color perception.

A premature attempt to explain something that thrills you will destroy your perceptivity rather than increase it, because your tendency will be to explain away rather than seek out.
