In America, the field of healthcare underwent extraordinary changes in the years from 1870-1920. A huge expansion in the number of patients spurred growth in the number of hospitals and physicians. The field became more professionalized and standardized. Dr. Cooper Holtzclaw, an eminent physician in Chattanooga, Tennessee, experienced these changes firsthand during his years of practice, and maintained his respected status among the citizens of Chattanooga.
