Georgia native Hugh Hartwell Milliing (1894-1984) was the son of Roscoe G. Milling, who practiced several areas of experimental medicine. He trained his son in these methods, which included magnetic treatment and the “Milling method of masseuring.” The younger Milling married Lillian Abell in 1916 and the couple moved to Mineral Wells the following year, where he purchased an existing sanitarium and began a thriving practice. He soon built a larger facility, and in 1929 constructed a final one at what is now the intersection of S.E. 23rd St. and Millsap Rd. In 1933 Milling donated property for a park named in his honor (later Pollard Park). In 1948 he sold his sanitarium to Dr. C.W. Irvine and moved his practice to Grand Prairie.
