Confederate Tannery

San Antonio, TX

Trained as an architect in Cologne and schooled in the building trades, John Hermann Kampmann fled the revolutionary upheavals of 1848 in central Europe and reached San Antonio that May, one of the German immigrants who reshaped the young Texas city. He rose from stonemason to leading contractor, leaving his mark on the Menger Hotel, St. Mark's Episcopal Church, the German-English School, and much else. Commissioned a Confederate captain in the Civil War, he recruited and equipped volunteers and managed army supplies before returning to his enterprises, ultimately buying the Menger Hotel he had helped build.

Early Spanish settlers first ground gunpowder here—charcoal from Hill Country wood, saltpeter scraped from bat guano in caves like Longhorn Cavern, and sulphur hauled by ox-cart from Mexico—to hunt game and defend against raids. The work was dangerous: even dampened powder sometimes sparked fires at the mill. During the Civil War the mill supplied powder to state troops, frontier defenders, and the home guard, worked by boys and men too old for military service.

In 1880, as the Gilded Age industrialized the American economy, San Antonio investors incorporated the Alamo Roman and Portland Cement Company on this site — the first Portland cement plant west of the Mississippi and only the second in the nation. Cement mixed here helped raise the Texas State Capitol in Austin, until the local raw material ran out and the works closed in 1907. Notably, Mrs. Charles Baumberger, Sr. ran the business from 1880 until it shut down, a rare directing role for a woman in heavy industry of that era.

In 1879 an Englishman named William Loyd found a blue limestone near San Antonio, and chemist George Kalteyer confirmed it held the right balance of lime and clay to make portland cement. The partners chartered their company in 1880 and built what became the first portland cement plant west of the Mississippi, its early pot kilns later joined by a tall Schoefer-type kiln. Cement from the works went into landmarks like the Texas State Capitol and Austin's Driskill Hotel before the plant relocated in 1908.
