The 4-1/2 story Star Mill building was erected in 1867 for $40,000. It was co-owned by Mattais Kochele and Henry Reitemeyer, one of the wealthiest merchants in town. The Star Mill was the first steam-powered grist mill in Hermann, Missouri. Today the building houses the Oncken Machine Shop. It is located at First and Gutenberg Streets.
