Gerhard Tenbusch was born in Germany and immigrated to the United States in 1882. He settled for a while in Boston, where he attended the Boston Technology Institute and perhaps was employed there as well through 1890. He moved to Duluth the next year to take a position of draftsman with McMillen & Radcliffe, Architects , By 1892 he is evidently practicing architecture, since credited with designing the John Fraser House at 1602 Jefferson Street. Only one house attributable to him, together with I. Vernon Hill, is located in the East End—the Walter and Sarah Turle House built in 1899. Tenbusch also designed the Sacred Heart Cathedral at 201 West Fourth Street in 1886, the Damiano Center at 206 W 4th Street (date and location unknown), “as well as many fine residences in the city and vicinity.” It is likely that many of the buildings referred to in this quote have been demolished, since they were likely concentrated in the central portion of the city, which was where most development occurred in the late 19th century.
