after him. World War II During World War II, the resort was closed in 1942 and converted to a convalescent hospital for the U.S. Navy (Pacific Theater), which was operational in July 1943. It re-opened to the public in December 1946. After the war, the resort's clinic operated on the third floor of the northern wing of the Sun Valley Lodge (wing closest to the Trail Creek Rd.) until the Sun Valley Community Hospital was built in 1961. That facility was named after Dr. John Moritz when he retired in 1973; the Nebraska-born surgeon had served as the resort's year-round physician for 33 years. The Moritz Hospital was closed shortly after the new St. Luke's branch hospital opened (south of Ketchum) in November 2000 and the Moritz building now serves as employee housing. Bill Janss (1964–77) After World War II, Harriman focused on his career in government service and the Union Pacific gradually lost interest in the resort. Rail service to Ketchum was discontinued in 1964 and that November the resort was sold to the Janss Investment Company, a major southern California real estate developer, headed by a former Olympic ski team member, Bill Janss (1918–96), founder of Snowmass. (Janss was an alternate on the 1940 team, but the games were cancelled due to the war). The railroad's management had called in the Janss Corporation as consultants and it was determined that it would take a lot of work and no less than $6 million for a face-lifting. The Union Pacific decided to sell and brothers Ed and Bill Janss bid just under $3 million. During this Janss era of ownership, the north-facing Warm Springs area was developed, as well as Seattle Ridge, and condominium and home construction increased significantly. Seven chairlifts were added, and the number of trails increased from 33 to 62. The first two double chairs on Warm Springs were installed in series in 1965; the upper "Limelight" had a vertical rise, the greatest in the U.S. at the time for a chairlift. Bill Janss bought out his brother's share of the resort and gained full control of Sun Valley in 1968. Snowmaking was introduced on a limited basis in the fall of 1975, covering up to an elevation of The original Seattle Ridge double chairlift was installed in 1976, but due to a very poor snow year in 1976–77 it was not operated until December 20,
