Downtown filled with the families who ran it. The Heard brothers kept an 1880s mercantile and opera house on the square; Stephen Heard's restored Victorian mansion is now the Heard-Craig Center for the Arts, and John Heard's daughter Bessie turned her love of wildlife into the Heard Natural Science Museum and Wildlife Sanctuary, with trails and live animals on the edge of town. The 1911 post office is now the Collin County History Museum.
A county-seat town grew here for two reasons: cotton and the railroad. When the Houston and Texas Central Railroad reached McKinney in 1872, the town became a regional shipping hub for cotton and grain, and the courthouse era was the era when, as people here still say, cotton was king. Gins, flour mills, and a cotton mill turned the rich Blackland Prairie soil into the town's livelihood for generations; by the 1920s Collin County was one of the largest cotton-producing counties in the entire country.
