Henry Alfred Kissinger (born Heinz Alfred Kissinger) is a German-born American bureaucrat, diplomat, and 1973 Nobel Peace Prize laureate. He served as National Security Advisor and later concurrently as Secretary of State in the Richard Nixon administration. Kissinger emerged unscathed from the Watergate scandal, and maintained his powerful position when Gerald Ford became President.

A proponent of Realpolitik, Kissinger played a dominant role in United States foreign policy between 1969 and 1977. During this period, he pioneered the policy of détente.

During his time in the Nixon and Ford administrations he cut a flamboyant figure, appearing at social occasions with many celebrities. His foreign policy record made him a nemesis to the anti-war left and the anti-communist right alike.
