In 1975, William MacKay, the general sales manager of a prosthetics company, participated in the bone surgery of Franklin Mirando at the request of the lead surgeons, David Lipton and Harold Massoff. MacKay had never gone to high school and had no medical training, but was interested in surgery; by the time of Mirando's operation, he had been frequently involved in surgical procedures, especially in those where prosthetics his company sold were involved.
