Dr. Ossian Sweet and His House Dr. Ossian Sweet’s substantial two-story brick home is listed on the National Register of Historic Places. In September 1925, Sweet tried to move his family into the then all-white Detroit suburb where the house is located. Residents reacted violently, determined to uphold “the present high standards of the neighborhood.” Dr. Sweet: Courtesy of the Burton Historical Collection, Detroit Public Library; house: Michigan State Historic Preservation Office.
