Lockhart came into being about 1904 when the Jackson Lumber Company mill was constructed there, the community being a company town. Many streets were named for Native American tribes. The mill was erected to handle the dense forests of yellow pine in what was known as the "Jackson Tract". The town was named for Standard Oil magnate and Pittsburgh, Pennsylvania financier, Charles Lockhart. In 1912, the mill employed around 1,000 workers and ran 24/7. At that time Lockhart was the largest lumber mill in the United States. Flooring for the famous Waldorf-Astoria Hotel in New York City came from Lockhart.
