How old was Kissinger when he and his family moved to the U.S.?

Born in 1923 in Germany, the young Kissinger was forced to flee Hitler’s anti-Semitic regime, settling with his family in New York City in 1938. After studying at City College, he joined the U.S. Army in 1943, serving as an interpreter and intelligence officer in Europe. Kissinger returned home in 1947 to a brilliant academic career at Harvard University, where he became a professor of government and inte-rnational affairs in 1957.
    A prominent interpreter of U.S. foreign policy, Kissinger served as a part-time foreign policy adviser to the Kennedy and Johnson administrations. In 1968 president-elect Richard Nixon appointed Kissinger as his national security adviser. Working closely together, the two set out to reshape the style and substance of U.S. foreign affairs.
    In 1973 Kissinger shared the Nobel Peace Prize with Le Duc Tho for secretly negotiating an end to the Vietnam War. The same year, he replaced William Rogers as secretary of state, while remaining as national security adviser. Instrumental in brokering an end to hostilities in the 1973 Yom Kippur War between Israel, Egypt and Syria, Kissinger then embarked on an intensive "shuttle diplomacy" effort to help mediate the long-standing Arab-Israeli conflict.
    Kissinger left office with the Ford Administration in 1977. He has since taught at Georgetown University and formed a highly successful international consulting group, Kissinger Associates, which represents companies that deal with China. He has appeared frequently as a media commentator on international affairs.
