Imagine a world where photography is a slow process that is impossible to master without years of study or apprenticeship. Such a world existed in 1973, when Steven Sasson, a young engineer, went to work for Eastman Kodak. Two years later he invented digital photography and made the first digital camera (picture above).
But Kodak's marketing department was not interested in it. Mr. Sasson was told they could sell the camera, but wouldn't - because it would eat away at the company's film sales.
