English: The Hiram Day Mansion, 441 Franklin Street, Buffalo, New York, June 2020. In both age and style a good representative example of the housing stock in the Allentown Historic District, the steep mansard roof with its arched dormer windows is a telltale trademark of the Second Empire style that was at the height of its popularity in 1870, the mansion's year of construction. Cyrus L. Gorton (1835-1876) was the first owner of the mansion, a local civil engineer and Civil War veteran who only lived in the house a few years before selling it in 1873 to local attorney Hiram C. Day (1826-1908), perhaps as a result of hardship over the economic depression that began that year. Day resided here until his death, whereupon it was purchased by Nellie Clark, the wealthy widow of a ship captain whose daughter Jane, a doctor who was one of the first crop of female physicians to graduate from the University of Buffalo Medical School, operated her doctor's office on one of the floors. It served as a boardinghouse of increasing disrepute during much of the time thereafter; it was purchased in 2003 by local real estate investor Don Gilbert who converted it into luxury apartments.
