In 1848, Carl Hilmar Guenther immigrated from Germany to the United States. After a short while spent in the midwest, he made his way to south Texas where he initially built a flour mill on Live Oak Creek in Fredericksburg, Texas. Within a few years, he moved his business to San Antonio and located it on the more powerful San Antonio River just south of the downtown area.
