Stevenson began his career as special counsel to the U.S. Navy Secretary during World War II. Later, he helped plan the first United Nations conference. And in 1948, he was elected governor of Illinois, soon getting national attention for reforms and modernizing highways, reorganized the state police, and doubled aid for education. Stevenson’s grandfather, also named Adlai, was Grover Cleveland’s Vice President. He was first to head the Democratic ticket in the 1952 election even though he had refused to campaign for the nomination.
Stevenson said that he would rather lose an election than “mislead the people by representing as simple what is infinitely complex.” That statement of principle turned out to be prophetic. He lost to Eisenhower in 1952 and again in 1956. From 1961 until his death in 1965, he served as U.S. ambassador to the U.N.
