Ralph Bunche, American political scientist, academic, and diplomat, Nobel Prize laureate (d. 1971)

Ralph Johnson Bunche (; August 7, 1903 – December 9, 1971) was an American political scientist, diplomat, and leading actor in the mid-20th-century decolonization process and US civil rights movement, who received the 1950 Nobel Peace Prize for his late 1940s mediation in Israel. Among black Nobel laureates he is the first African American and first person of African descent to be awarded a Nobel Prize. He was involved in the formation and administration of the United Nations and played a major role in both the decolonization process and numerous peacekeeping operations sponsored by the UN. In 1963, he was awarded the Presidential Medal of Freedom by President John F. Kennedy. At the UN, Bunche gained such fame that Ebony magazine proclaimed him perhaps the most influential African American of the first half of the 20th century and "[f]or nearly a decade, he was the most celebrated African American of his time both [in the US] and abroad."Bunche served on the US delegation to both the Dumbarton Oaks Conference in 1944 and United Nations Conference on International Organization in San Francisco in 1945 that drafted the UN charter. He then served on the American delegation to the first session of the United Nations General Assembly in 1946 and joined the UN as head of the Trusteeship Department, beginning a long series of troubleshooting roles and responsibilities related to decolonization. In 1948, Bunche became an acting mediator for the Middle East, negotiating an armistice between Egypt and Israel. For this success he was awarded the Nobel Peace Prize in 1950.

Bunche continued to serve at the United Nations, working on crises in the Sinai (1956), the Congo (1960), Yemen (1963), Cyprus (1964) and Bahrain in 1970, reporting directly to the UN Secretary-General. He also chaired study groups dealing with water resources in the Middle East. In 1957, he was promoted to Under-Secretary-General for special political affairs, having prime responsibility for peacekeeping roles. In 1965, Bunche supervised the cease-fire following the war between India and Pakistan. He retired from the UN in June 1971, six months before his death.
