Today, if we want to take a photo, we unlock our phone, aim, and click. It can be done on a whim, without a second thought. We document everything from new haircuts to latte art, cute cats to baby’s first smile. But prior to the 1900s, photography was the exclusive domain of professionals and dedicated hobbyists -- people willing to learn complex skills and spend hours on the craft.

Responsible for that shift was a man named George Eastman. Armed with a radical vision for what photography could be, and a cold-blooded business sense, Eastman delivered photography to the masses and altered the way most of us experience our lives over time.
