The American physicist, inventor, and manufacturer Edwin Herbert Land (1909-1991) was the first to develop successfully a synthetic light-polarizing material and to develop a camera for one-step photography.

Edwin Land was born in Bridgeport, Connecticut in 1909. After attending preparatory school he entered Harvard University. He soon became involved in studying polarized light and began experiments to develop a way of creating the effect artificially. In normal light, wave vibrations take place in all directions; in polarized light, these vibrations are controlled and permitted to travel only in certain directions.

In 1828 a prism had been invented that was used to polarize light for optical instruments. The great expense of the prism, however, limited its use, and a search was begun for a cheaper means of creating the same effect; most attempts had concentrated on trying to grow very large crystals in the laboratory.
