Land further developed and produced the sheet polarizers under the Polaroid trademark. The company was renamed the Polaroid Corporation in 1937. After a few early successes developing polarizing filters for sunglasses and photographic filters, Land obtained funding from a series of Wall Street inventors for further expansion. Wheelwright, his instructor, came from a family of financial means and agreed to fund the company. In 1932 he established the Land-Wheelwright Laboratories together with his Harvard physics instructor to commercialize his polarizing technology. She would then write up the homework and hand it in so he could receive credit and not fail the course. Often his wife, at the prodding of his instructor, would extract from him the answers to homework problems. 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. However, he still 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 micrometre-sized polarizing crystals that were coaxed into perfect alignment with each other.Īfter developing a polarizing film, Edwin Land returned to Harvard. He also availed himself of the New York City public library to scour the scientific literature for prior work on polarizing substances. Instead, he would sneak into a laboratory at Columbia University late at night to use their equipment. Because he was not associated with an educational institution, he lacked the tools of a proper laboratory. In New York City, he invented the first inexpensive filters capable of polarizing light. After his freshman year, he left Harvard for New York City. He studied chemistry at Harvard University. The library there was posthumously named for him, having been funded by grants from his family. He was an alumnus of the Norwich Free Academy in Norwich, Connecticut, a semi-private high school. Edwin was born in Bridgeport, Connecticut to Harry and Helen Land.
