English: The Grace Millard Knox House, 800 Delaware Avenue, Buffalo, New York, June 2020. Part of the locally- and NRHP-listed Delaware Avenue Historic District, this extravagant stone manse was built over a course of three years, ending in 1918, by architect Charles Pierpont H. Gilbert, who employed an elegant French Renaissance style with a symmetrical façade and a U-shaped floor plan: projecting side pavilions flank a recessed central elevation with French doors on the ground floor topped with round arches, the second floor windows sporting head molds bracketed by end ancones and, in the middle, an ornamental balcony in cast iron supported by brackets in the form of acanthuis leaves. A roofline balustrade crowning a dentillated cornice completes the effect. Grace Millard Knox (1862-1936) was the wife of retail magnate Seymour H. Knox, the vice-president of the Woolworth chain of stores; she moved here after her husband's death from their former house further up Delaware Avenue and lived here until her own death eighteen years later. Daughter Marjorie Knox Klopp (1900-1971) inherited the house and sold it in 1969 to the Montefiore Club, who added athletic facilities to the rear of the building including three squash courts, a gym and locker rooms; it's served as the corporate offices of CTG (formerly Computer Task Group) since 1978.
