In Robertson County, Hearne was developed in 1868, and was named for the Christopher Columbus Hearne family of Lowdes County, Alabama, who moved to Texas and established large cotton plantations. The city lies at the intersection of U.S. 79 and Texas 6, as well as the state's major east-west and north-south rail lines.
Rosie Lee Moore, the last live model for Quaker Oats Company's Aunt Jemima, was from Hearne. She toured for the company during the 1950s and '60s promoting their products, especially the pancake mix. She died in 1967 and is buried at the Hammond Colony Cemetery northeast of the city.
