Vice President Lyndon B. Johnson assumed the presidency upon Kennedy's death. On the following day, August 5, Kennedy and Ensign George Ross made the one hour swim to Naru Island, an additional distance of about .5 miles (0.80 km) southwest, in search of help and food. Kennedy and Ross found a small canoe, packages of crackers, candy and a fifty-gallon drum of drinkable water left by the Japanese, which Kennedy paddled another half mile back to Olasana in the acquired canoe to provide his hungry crew. His brother-in-law, Sargent Shriver, was its first director. Through this program, Americans volunteered to help developing nations in fields like education, farming, health care, and construction.
