Purpose and benefits

Edwin Land (1909–1991) pioneered instant photography for the masses with his invention of the Polaroid camera. Other important enterprises such as Land’s groundbreaking work into light polarisation at his Harvard University laboratories during the 1930s are less well known. And few people realise that it was a friend’s fishing trip that led to the invention of Polaroid sunglasses, or that Land released a revolutionary new instant movie camera at the same time as Sony was introducing videotape in 1977.
