Background: Born and raised in Boise, Idaho, Church was the younger of the two sons of Frank (II) and Laura Bilderback Church. His father co-owned a sporting goods store and took the sons on fishing, hunting, and hiking outings in the Idaho mountains. The family was Catholic and conservative, and Frank III attended St. Joseph's School as a youngster, where he went by the nickname "Frosty." His older brother Richard became a career officer in the U.S. Marines Corps, and retired as a colonel.
Context: Church is also remembered for his voting record as a strong progressive and environmental legislator, and he played a major role in the creation of the nation's system of protected wilderness areas in the 1960s. In 1964, Church was the floor sponsor of the national Wilderness Act. In 1968, he sponsored the Wild and Scenic Rivers Act and gained passage of a ten-year moratorium on federal plans to transfer water from the Pacific Northwest to California. Working with other members of Congress from northwestern states, Church helped establish the Hells Canyon National Recreation Area along the Oregon-Idaho border, which protected the gorge from dam building. He was also the primary proponent in the establishment of the Sawtooth Wilderness and National Recreation Area in central Idaho in 1972.  Church also was instrumental in the creation of Idaho's River of No Return Wilderness in 1980, his final year in the Senate. This wilderness comprised the old Idaho Primitive Area, the Salmon River Breaks Primitive Area, plus additional lands. At 2.36 million acres (9,550 km2), over 3,600 square miles (9,300 km2), it is the largest wilderness area in the nation outside of Alaska. It was renamed the Frank Church-River of No Return Wilderness in 1984, shortly after the diagnosis of his pancreatic cancer. Idaho Senator Jim McClure introduced the measure in the Senate in late February, and President Reagan signed the act on March 14, less than four weeks before Frank Church's death on April 7.  Frank Church was considered a progressive (remarkable considering that he represented one of the most conservative states in the nation), though he was a strong opponent of gun control. He, in 1979, was the first in Congress to disclose and protest the presence of Soviet combat troops in Cuba. According to the Christian Science Monitor, this stance somewhat disarmed his opponent's charge in the 1980 campaign that Church's performance on the Foreign Relations Committee had helped to weaken the US militarily. In 1974, Church joined Senator Frank Moss, D-Utah, to sponsor the first legislation to provide federal funding for hospice care programs. The bill did not have widespread support and was not brought to a vote. Congress finally included a hospice benefit in Medicare in 1982.  In late 1975 and early 1976, a sub-committee of the U.S. Senate led by Church concluded that members of the Lockheed board had paid members of friendly governments to guarantee contracts for military aircraft in a series of illegal bribes and contributions made by Lockheed officials from the late 1950s to the 1970s. In 1976, it was publicly revealed that Lockheed had paid $22 million in bribes to foreign officials in the process of negotiating the sale of aircraft including the F-104 Starfighter, the so-called "Deal of the Century."  Church also sponsored, along with Pennsylvania Republican John Heinz, the "conscience clause," which prohibited the government from requiring church-affiliated hospitals to perform abortions.
