Often his wife would extract from him the answers to homework problems, at the prodding of his instructor. According to biographer Peter Wensberg, once Land could see the solution to a problem in his head, he lost all motivation to write it down or prove his vision to others. Land especially when he set up visiting posts to Harvard and Massachusetts Institute of Technology. Despite not receiving a college degree, he was still referred to from many as Dr.

Land returned to Harvard University after developing the polarizing film, but he did not finish his studies or receive a degree. His breakthrough came when he realized that, instead of attempting to grow a large single crystal of a polarizing substance, he could manufacture a film with millions of micron-sized polarizing crystals that were coaxed into perfect alignment with each other. He also availed himself of the New York Public Library to scour the scientific literature for prior work on polarizing substances. He was not associated with an educational institution and lacked the tools of a proper laboratory, making this a difficult endeavor, so he would sneak into a laboratory at Columbia University late at night to use their equipment. There he invented the first inexpensive filters capable of polarizing light, which he called Polaroid film. He studied physics at Harvard University, more specifically, optics, but left after his freshman year, moving to New York City. The library there was posthumously named for him, having been funded by grants from his family.

Land Medal in recognition of his contributions to the field of optics.Land attended the Norwich Free Academy at Norwich, Connecticut, a semi-private high school, and graduated in the class of 1927 with honors. The following year, the Optical Society and the Society for Imaging Science and Technology established the Edwin H. In 1988, he received the National Medal of Technology. Three years later, he resigned as chairman of Polaroid and founded the Rowland Institute for Science at Harvard University (now the Rowland Institute at Harvard). patents and was awarded the Medal of Freedom in 1963-the highest honor granted to civilians in the U.S.Īlthough he ended up dropping out of Harvard, Land received honorary degrees from Harvard, Yale and Columbia and was inducted into the National Inventors Hall of Fame in 1977. Over his lifetime he was issued over 500 U.S. His “retinex” theory said that all visual levels of processing, from the retina in the eye to the visual cortex in the brain were necessary for human beings to process color.

in World War II to proposing the "retinex" theory of human color perception. Land spent his entire adult life experimenting and innovating in the field of optics, from producing recording systems used by the U.S. Land even created an instant color movie-making system, "Polavision," in 1978, but this never enjoyed the commercial success of his still-photography cameras. It was the first device to use an instant film pack combined with a built-in battery. His revolutionary "SX-70" camera, introduced in 1972 replaced the wet, peel-apart development process with dry films that developed in light. Following this success, Land continued to improve his invention, eventually creating his color film, "Polacolor” in 1963. The Polaroid Land Camera Model 95 (Patent #2,543,181) was first offered for sale on November 26, 1948. In 1947, Land demonstrated the instant camera at the Optical Society of America’s winter meeting. Land used the principle of diffusion transfer to reproduce the image recorded by the camera's lens directly onto a photosensitive surface. Inspired, Land ended up creating a system of one-step photography: A camera that instantly printed photographs the moment they were captured. It was 1943 when his three-year-old daughter had asked him why she couldn't see a photo he had taken of her right away. But it was through his Polaroid Corporation (founded in 1937) that Land was immortalized, for his invention and marketing of instant photography. Following high school, he attended Harvard University where he conceived and produced the first modern filters to polarize light, patented in 1929. Land was born in Bridgeport, Connecticut on and attended the Norwich Free Academy, graduating in 1927. This is all thanks to the work of Edwin Herbert Land.
