Mildred was founded in 1907 by Sam Dermott for the Great Western Cement Company. The community was named for the daughter of J. W. Wagner a local industrialist, and the president of the cement company. Cement was shipped all over the world, and cement from the plant was used to construct the Liberty Memorial and World War I museum in Kansas City, Missouri. At its peak the cement plant employed 375, but the community lost most of its population when the plant closed.
The community was previously served by the Missouri–Kansas–Texas Railroad, which maintained a passenger depot in the community, as well as spur lines that served the cement plant and the grain elevator.
