[++] "Edwin Herbert Land, (born May 7, 1909, Bridgeport, Conn., U.S.died March 1, 1991, Cambridge, Mass.), American inventor and physicist whose one-step process for developing and printing photographs culminated in a revolution in photography unparalleled since the advent of roll film. While a student at Harvard University, Land became interested in polarized light, i.e., light in which all rays are aligned in the same plane. He took a leave of absence, and, after intensive study and experimentation, succeeded (1932) in aligning submicroscopic crystals of iodoquinine sulfate and embedding them in a sheet of plastic. The resulting polarizer, for which he envisioned numerous uses and which he dubbed Polaroid J sheet, was a tremendous advance. It allowed the use of almost any size of polarizer and significantly reduced the cost. With George Wheelwright III, a Harvard physics instructor, Land founded the Land-Wheelwright Laboratories, Boston, in 1932. He developed and, in 1936, began to use numerous types of Polaroid material in sunglasses and other optical devices. Polaroid was later used in camera filters and other optical equipment."
