Imagine a world where photography is a slow process that is impossible to master without years of study or apprenticeship. A world without iPhones or Instagram, where one company reigned supreme. 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.
Mr. Sasson, all of 24 years old, invented the process that allows us to make photos with our phones, send images around the world in seconds and share them with millions of people. The same process completely disrupted the industry that was dominated by his Rochester employer and set off a decade of complaints by professional photographers fretting over the ruination of their profession.
