1.2 Marriage and college years. Bush met Barbara Pierce at a Christmas dance in Greenwich in December 1941, and, after a period of courtship, they became engaged in December 1943. While Bush was on leave from the navy, they married in Rye, New York, on January 6, 1945. The Bushes enjoyed a strong marriage, and Barbara would later be a popular First Lady, seen by many as 'a kind of national grandmother'. Their oldest daughter, Robin, died of leukemia in 1953. After the 1970 Senate election, Bush accepted a position as a senior adviser to the president, but he convinced Nixon to instead appoint him as the U.S. Ambassador to the United Nations. The position represented Bush's first foray into foreign policy, as well as his first major experiences with the Soviet Union and the People's Republic of China, the two major U.S. rivals in the Cold War.
