Hamilton Disston was an industrialist and real-estate developer who purchased 4 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.

Henry Disston was an English American industrialist who founded the Keystone Saw Works in 1840 and developed the surrounding Tacony neighborhood of Philadelphia to build housing for his workers. His company became the Disston Saw Works and was the top manufacturer of hand saws in the United States during the late 19th-century and early 20th century.
