“No man in history can surpass Edwin Land as the Maker of Imaging Systems. During his entire life Land was fascinated with the ‘interaction of light and matter.’ The constant theme throughout his 535 patents is new ways to make images. That theme holds equally well for all three major areas of Land’s research—polarizers, photography and human color vision—and even in the areas of public service for the United States. Land didn’t invent just one new instant imaging system; he invented and patented for Polaroid a litany of new systems that were chemically and physically very different from each other.”
