Daniel C. Cooper (November 21, 1773 — July 13, 1818) was an American surveyor, farmer, miller and political leader. Biography He was born in the Passaic Valley at Long Hill, Morris County, New Jersey, the son of wealthy farmer George Cooper (20 August 1745 — 20 September 1801) and Margaret Lafferty. George’s father Daniel was born at sea on the voyage from Holland about 1695. Educated as a surveyor, when Daniel C. Cooper was about twenty years old, he went west to Fort Washington near Cincinnati, Ohio to look after the interests of Jonathan Dayton, who owned lands and was otherwise interested in the "Symmes Purchase." This gave Cooper employment in his occupation as surveyor, and was also a favorable opportunity for observation and selection of lands for himself. Judge John Cleves Symmes, a land speculator from New Jersey, initiated much of southwestern Ohio's settlement and in late 1795, he sold Arthur St. Clair, Governor of the Northwest Territory, General James Wilkinson, Israel Ludlow and New Jersey Congressman Jonathan Dayton the land that became known as the "Dayton Purchase." The four men paid $0.83 an acre for 60,000 acres (240 km²) at the confluence of the Great Miami and Mad rivers. Israel Ludlow named the village after his friend Jonathan Dayton, who ironically never set foot in the town. Ludlow also laid out the streets, which at four poles (66 ft) were wide enough to "turn a coach and four." Daniel Cooper headed the team that surveyed the land and laid out the town site in 1795. In 1796, Dayton Township, a large area containing parts of current Montgomery, Greene, Miami, Clark, Champaign, Logan, and Shelby Counties, was formed. Daniel Cooper was appointed tax assessor. The highest tax assessed was Daniel Cooper's $6.25, which included the gristmill he operated. In 1797, Daniel Cooper laid out the Mad River Road, the first overland connection between Cincinnati and Dayton. This opened up the "Mad River Country" at Dayton and the upper Miami Valley to settlement. When Symmes later failed to meet his financial obligations to the federal government, Ludlow, St. Clair, Wilkinson, and Dayton waived their right to purchase the property from the government. In 1800, the United States Government offered to sell the property to the residents at the rate of $2.00 an acre, but this was far beyond the means of the inhabitants - and at a higher price than
