Howard E. and Mary Butt House In 1929 entrepreneur Howard E. Butt moved the headquarters of his developing grocery business to Harlingen. The following year, Howard and his wife, Mary, bought this house from its builders, John and Ruth Townsend, a few months after its completion. During the 1930s, Howard's business (H.E.B. Grocery) grew to more than 28 stores in the Rio Grande Valley and South Texas. Known also for their philanthropy and civic work in Harlingen, Howard and Mary Butt lived here until 1940 but owned the house until 1943. Distinguished by its Palladian windows and spiral entry columns, the architectural style of the house is best described as Italian Renaissance. Recorded Texas Historic Landmark - 2000
