Edwin H. Land
1909 - 1991
Edwin Land is mostly known as the founder of the Polaroid company and the instant camera (and second only to Thomas Edison in the number of patents granted). But Land was not only an inventor: he was also a genuine scientist, developing over three decades the Retinex theory of color vision with a collaborator, J. McCann. The theory, as its name suggests (a combination of retina and cortex), held that color sensation was the product of calculations, either in the eye (retina) or in the brain (cortex), or both, in which light in each of the three major wavebands were compared.
