Constructed about 1915 by John Sparger, Jr., this building first served as the residence of D. W. Sweeney, a local merchant and banker. In 1956 it was purchased by Dr. Joe A. Risser and opened as an 18-bed hospital, one of several doctor-operated clinics that served the medical needs of Bonham residents. Risser Hospital gained national attention on Nov. 16, 1961, when Sam Rayburn, Speaker of the U.S. House of Representatives, died in the northeast downstairs room while a patient here. Dr. Risser, Rayburn's personal physician, operated the facility until 1971, when it was closed. (1981)
