Philip Hahn purchased this property in 1902. While the 1905 Baist map of Denver shows a small frame residence at this location, a 1908 building permit indicates that the current brick residence replaced it. It is possible that the Hahn family lived in the existing frame residence before building the more permanent house that stands here today. Hahn was a "German from Russia," whose family immigrated from Germany to Russia beginning around the reign of Catherine the Great. As the political climate shifted, many Germans from Russia immigrated to the United States, with most settling in Colorado, Kansas and Nebraska. Hahn was born c.1869 in Russia, and immigrated to the United States about 1900 with his wife Christine and son Henry. Once here, the couple added daughters Christina and Annie to the family. Hahn worked for the railroad in various positions, including as a teamster, a general laborer and a machinist. Ownership of the property stayed in the Hahn family until 1951. The Hahn children lived in the home periodically through their early adulthood.
