Guenther's Upper Mill, Site of

San Antonio, Bexar County, Texas

Marker Inscription

Trained as a millwright in his native Germany, Carl H. Guenther (1826-1902) started his San Antonio operation in 1859 at the site of the present Pioneer Flour Mills. In 1868 he built another dam and mill upstream at this location. Because it was closer to town, the upper mill was an outlet for products from both plants. About 1900 the Guenther family began operating exclusively from the downstream facility. The vacated upper mill housed a macaroni factory, an ice cream company, and later a garage. In 1926 the structure was razed to widen the San Antonio River. (1979)

The Story

German-trained millwright Carl H. Guenther founded his San Antonio milling operation in 1859 and, in 1868, built this second dam and mill upstream at a spot closer to town. The upper mill served as an outlet for both of his plants before the family consolidated at the downstream Pioneer Flour Mills around 1900. The vacated building later housed a macaroni factory, an ice cream company, and a garage before being razed in 1926.

Why it matters

Guenther's mills mark the rise of German immigrant enterprise that helped power San Antonio's industrial growth in the nineteenth century.

Charles F.A. and Emilie Hummel House

San Antonio, TX

In the decades after the Civil War, San Antonio's prosperous German community left a lasting mark on the city's streets and skyline. Charles F.A. Hummel, orphaned young and raised in the family gun-and-ammunition trade, rose to serve as city treasurer and auditor while remaining a pillar of that German world. In 1884 he and his wife Emilie commissioned architects Wahrenberger and Beckmann to build this ornate two-story limestone house, its Italianate pavilion, full-height gallery, and carved quoins announcing a family that had arrived.

Alfred Giles, born in England in 1853, trained as an architect's apprentice in London before moving to Texas for his health in 1873. Settling in San Antonio, he opened his own firm in 1876 and designed grand residences for the city's leading families along King William Street. In 1883 he built two modest homes at 306 and 308 King William, living in the latter and later giving it, remodeled, to his daughter as a wedding gift.

After Sartor sold the house in 1909 it served in turn as a medical office and a literary studio, keeping its wide front porch and Italianate detailing throughout.
