The Double U Company was a land colonization company charted in 1907 by breakfast food magnate Charles William Post (1854-1914) of Battle Creek, Michigan. From 1906 to 1907, Post purchased over 200,000 acres of land in Garza, Lynn and Hockley counties of Texas, which included the Curry Comb Ranch, the OS Ranch, the Fountain G. Oxsheer Ranch, and a portion of John B. Slaughter's U Lazy S Ranch. Originally named Post City, the town of Post in Garza County began as a tent city in 1906, and by 1916, after an extensive real estate campaign, Post and the surrounding area contained approximately 3,000 inhabitants and 14 private corporations which together held over 1.2 million dollars in capital stock. The Double U Charter expired in 1957, and C. W. Post's heirs established the Post-Montgomery Ranch and the Double U Ranch, consisting of rangeland near the towns of Levelland, Tahoka and Post.
