With the slogan "you press the button, we do the rest," George Eastman put the first simple camera into the hands of a world of consumers in 1888. In so doing, he made a cumbersome and complicated process easy to use and accessible to nearly everyone.
1854 George Eastman was born in New York, but his family moved to Rochester, New York four years later.
1878 George Eastman was one of the first to demonstrate the great convenience of gelatin dry plates over the cumbersome and messy wet plate photography prevalent in his day.

Eastman was one of the first to successfully mass-produce dry plates for photographers.
