While working as a diplomat for the newly created United Nations, Ralph Bunche conducted the seemingly impossible negotiations resulting in the 1949 armistice between the year-old nation of Israel and its Arab neighbors. His efforts demonstrated that nations can resolve issues peaceably and also that the United Nations can serve as an effective facilitator among nations. For this exemplary accomplishment, Bunche was awarded the Nobel Peace Prize in 1950.
Born at the turn of the century, Clifton R. Wharton, Sr. served the United States as a Foreign Service Officer through the 20th century's most tumultuous period. Wharton passed the Foreign Service exam in 1925, which made him the first African-American Foreign Service Officer. Under Presidents Eisenhower and Kennedy, Wharton became the first African-American to lead a delegation to a European country and the first African-American to come from within the Foreign Service ranks to become an ambassador.
