Christian Dietert was a German millwright.  He built a mill on the Guadalupe River soon after he arrived in 1857. This mill played an important role in the growth of Kerrville by processing crops and providing lumber for area homes and buildings.  

Charles Schreiner bought the sawmill & gristmill operation in 1882.
