Prosper was the central stop for the railroad between Dallas and Sherman. When community officials applied for a Post Office with the name “Richland,” they were informed that city name was already taken. Postmaster B.J. Naugle asked for an alternative name and J.C. Slaughter suggested the name “Prosper,” because crops that year had been very prosperous.
The Town of Prosper was incorporated in 1914 with a commission form of government and a population of 500. U.N. Clary was Mayor and served in that position for the next 49 years.
Prosper was named in the D Magazine 2010 Best Suburbs List as the 5th Best Suburb in the Dallas Metropolitan Area.[8]
Prosper High School cost $113.5 million to construct and is 590,000-square-feet, complete with a medical tech lab, a restaurant-worthy kitchen, a greenhouse, a broadcast studio and an indoor football practice facility.
The Town of Prosper holds an annual Christmas festival and Fourth of July event. Each May, Prosper Founders Fest celebrates its history, people and arts. The event combines the Prosper Fire Department’s IBCA-sanctioned Barbecue Cookoff, a 5K race, an art show and music festival and a Sunday Family Fellowship.
