This long-running series, loosely based on a film by the same name by Robert Altman, focuses on the lives of a team of doctors and nurses at a U.S. Mobile Army Surgical Hospital (MASH) during the Korean War. Head nurse, Major Margaret Houlihan, was just as strong, capable, intelligent, and determined as the doctors surrounding her. Loretta Swit won two Emmys for her portrayal of Major Houlihan.
