Architect The Michael Jacobs House, at 4 W. First Avenue North in Columbus in Stillwater County, Montana, also known as the Jacobi House, is a Renaissance Revival-style house built of locally quarried sandstone during 1900-1907. It was listed on the National Register of Historic Places in 1987. It was built by, and home of, Michael Jacobs, an immigrant who later became mayor of Columbus. Michael Jacobs was born in Vinchia Turo, Italy in 1862 as Michael Angelo Jacobucci (he changed his name to Jacobi after coming to America, and then to Jacobs when he settled in Montana). Serving originally as a stone cutter and mason, he apprenticed in the granite and marble quarries of the mountains near his home.
