1019 Clarkson Street was built in 1902 for Robert and Eleanor Hanington at a cost of $5000. The building permit lists the architects as Gove and Walsh, and the builders as Killie and Royce. While no records could be located regarding the builders, architects Aaron Gove and Thomas Walsh contributed significantly to Denver’s built landscape during their three decade-long partnership. Notable buildings include the historic Sugar Building, built in downtown Denver in 1906 for the Great Western Sugar Company; Cathedral Basilica of the Immaculate Conception, at Colfax and Logan Street (Gove & Walsh took over after the original architect became ill); and the Barteldes Seed Warehouse on Wynkoop Street, now used as residential lofts.
Robert and Eleanor Hanington had been married for just a year when 1019 Clarkson Street was built. Robert worked for the Hendrie & Bolthoff Manufacturing & Supply Company, where he was in charge of the machinery and engineering departments. Eleanor Hanington was the daughter of Dean Henry Martyn Hart, the rector and dean of St. John’s Cathedral in the Wilderness in Denver. Dean Hart presided over the church for forty-one years, and was one of three Denver clergy that founded the Denver Charity Organization, later named the United Way. Robert and Eleanor Hanington had two daughters, Margaret and Clara, who lived with them at 1019 Clarkson until at least 1930 when the girls were in their early twenties. By 1945, Robert was the vice president and treasurer of Hendrie & Bolthoff.
