Hamilton Disston (August 23, 1844 – April 30, 1896) was an industrialist and real-estate developer who purchased four million acres (16,000 km²) of Florida land in 1881, an area larger than the state of Connecticut, and reportedly the most land ever purchased by a single person in world history. Disston was the son of Pennsylvania-based industrialist Henry Disston who formed Disston & Sons Saw Works, which Hamilton later ran and which was one of the largest saw manufacturing companies in the world.
