Arthur H. Vandenberg

Arthur Hendrick Vandenberg (1884–1951) was an American Republican statesman from Grand Rapids, Michigan, who served in the US Senate from 1928 until his death in 1951. An editor of the Grand Rapids Herald before entering politics, Vandenberg was initially a staunch isolationist who opposed US involvement in foreign alliances during the 1930s.

Following the Japanese attack on Pearl Harbor, Vandenberg underwent a historic intellectual conversion to internationalism. On January 10, 1945, he delivered a speech on the Senate floor renouncing isolationism and co-drafted the United Nations Charter in San Francisco. As Chairman of the Senate Foreign Relations Committee from 1947 to 1949, he worked hand-in-hand with Democratic President Harry S. Truman to pass the Marshall Plan and authored the 1948 Vandenberg Resolution, famously establishing the principle that 'politics stops at the water's edge' and making possible the creation of NATO.
