William A. A. Mueller, a grocery salesman and widower, owned this Gabled Front house from 1899 until 1906. He resided there with his daughter Marcella, and his brother-in-law William C. Miller, a bartender. After William's second marriage in 1904 and 1905, the family moved to 501 Lafayette, and may have kept this property for investment purposes.
