Georgia native Hugh Hartwell Milling (1894-1984), son of Roscoe G. Milling, was trained by his father in experimental medical methods that included magnetic treatment and the “Milling Method of Masseuring.” After marrying Lillian Abell in 1916, he moved with her to Mineral Wells the following year, bought an existing sanitarium, and began a thriving practice. He later 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 he donated property for a park named in his honor, later called Pollard Park. In 1948 he sold his sanitarium to Dr. C.W. Irvine and moved his practice to Grand Prairie.
