War I veteran himself, asked the former president to direct postwar food relief. In a tearful scene in Truman's office, Hoover gratefully accepted the challenge and traveled 35,000 miles throughout Europe to once again oversee the movement and distribution of food to thousands of starving Europeans. 121 The ex-president also oversaw two commissions on the reorganization of the executive branch in 1947 under Truman and again in 1954 under Dwight D. Eisenhower. Deaf and nearly blind, Hoover died of colon cancer in 1964, somewhat vindicated, but never able to recapture the popularity among reporters and citizens that had marked his early career. As Roger Simon suggested in 1992, ex-presidents, especially those unpopular with reporters, suffer for a long, long time.
