Dumas, Moore County
Created 1876 from Bexar Land District. Named in honor of Edwin W. Moore (1810-1865), commodore of the navy, Republic of Texas. County was organized July 5, 1892, with Dumas (named for promoter of the townsite) as county seat. Stagecoach and freighters furnished transportation in early days. The county was thinly settled; ranching was the main industry, prior to discoveries of oil and gas in 1926. A zinc smelter was built in 1936. Economy is now based on petrochemicals, helium, oil, gas, cattle feeding, beef packing, ranching, grains, soybeans and corn. (1991)
