Frontier physician Andrew Taylor Still, MD, DO, founded the American School of Osteopathy (now the A.T. Still University-Kirksville (Mo.) College of Osteopathic Medicine) in Kirksville, Missouri in 1892 as a radical protest against the turn-of-the-century medical system. A.T. Still believed that the conventional medical system lacked credible efficacy, was morally corrupt, and treated effects rather than causes of disease. He founded osteopathic medicine in rural Missouri at a time when medications, surgery, and other traditional therapeutic regimens often caused more harm than good. Some of the medicines commonly given to patients during this time were arsenic, castor oil, whiskey, and opium. In addition, unsanitary surgical practices often resulted in more deaths than cures.
