claim_to_fame: Science

best_know_for: Edwin H. Land was an American scientist and inventor, best known as the co-founder of the Polaroid Corporation and the inventor of instant photography. “Dr. Land,’’ as most people referred to him, left Harvard College before graduation to start inventing in a Cambridge garage. In 40 years, Land built up a company that did about $1.4 billion of business all over the world in 1979 with over 20,000 employees. He stuck to his guns, never diversified into other businesses, never sold out to another company, and never borrowed money on a long-term basis. Land was awarded more than 500 patents, and other Polaroid researchers hundreds more. The Polaroid company was a juggernaut of innovation. In modern terms, Polaroid was the Apple of its time with a brilliant leader in Edwin Land, a scientist who guided the company as the CEO for several decades. But the company suffered a long decline starting in the ’80s leading to bankruptcy in the 2000s.
