John Bosley Ziegler

John Bosley Ziegler (''ca.'' 1920–1983) — known as John Ziegler and Montana Jack — was the American physician who originally developed the anabolic steroid Methandrostenolone (Dianabol, DBOL) which was released in the USA in 1958 by Ciba. He pioneered its athletic use as an aid to muscle growth by bodybuilders, administering it to U.S. weightlifting champion Bill March of the York Barbell Club in 1959 when he was the physician to the U.S. Weightlifting team. It was banned by the Food and Drug Administration (FDA) under the Controlled Substances Act. Later in his life, he was outspoken against its use in sport, saying "It is bad enough to have to deal with drug addicts, but now healthy athletes are putting themselves in the same category. It's a disgrace. Who plays sports for fun anymore?" Ziegler suffered from heart disease, which he partially ascribed to his experimentation with steroids, and he died from heart failure in 1983.
