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 Pittsburg, Pennsylvania financier, Charles Lockhart. In 1912, the mill employed around a thousand 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. The milling facility was served by both the Central of Georgia Railroad and the Louisville and Nashville Railroad, connecting through nearby Florala, Alabama. "The mill, however, closed in 1940, and historical accounts offer two reasons. Military enlistments prior to U.S. entry in World War II caused a labor shortage, or company officials sold their holdings and the land to the residents after cutting all the timber in the area and deciding not to wait for replanted timber to mature. Jackson Lumber Company also donated much land to the state that was replanted and developed by the Civilian Conservation Corps into Geneva State Forest in neighboring Geneva County." This land had little value after it had been clear cut, the practice of the time, and being unable to sell the now-deforested acreage during the Great Depression, the company donated it to the state in the 1930s rather than pay taxes on it.
