Located at 695 North Avenue in Atlanta, the Dupre Excelsior Mill may have been built as early as 1890 by DuPre Manufacturing Company. However, the mill fails to appear on Atlanta city maps in 1892 and 1899, which both show the property as vacant. The first possible reference to the mill exists in the report of the death of Hubert Neal on July 17, 1899. According to the report, his accident occurred at the Atlanta Excelsior Works, which may or may not be the same facility since at the time there were three excelsior factories in Atlanta. The earliest concrete confirmation of the mill seems to be three lawsuits filed against Dupre in 1907 for accidents that occurred at the facility. The mill does appear on the Sanborn-Perris fire insurance map of 1911. At that time, the only road connecting it was Angier Street. It was noted to have been heated by steam power, no lighting, and a private water supply from a well 10 feet in diameter and 40 feet deep. A watchman made hourly rounds to seven stations.
