Sir Winston Leonard Spencer Churchill (18741965)
A shadow has fallen upon the scenes so lately lighted by the Allied victory . From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent.
WINSTON CHURCHILL, The Sinews of Peace, address at Westminster College, Fulton, Missouri, March 5, 1946.Winston S. Churchill: His Complete Speeches, 18971963, ed. Robert Rhodes James, vol. 7, p. 7290 (1974).
The term iron curtain was used in this sense as early as 1920, and Churchill had used it earlier in a telegram to President Harry Truman, May 12, 1945: An iron curtain is drawn down upon their front. We do not know what is going on behind.Winston Churchill, Triumph and Tragedy (vol. 6 of The Second World War), p. 573 (1953). It was Churchills use of the term in this speech, however, which popularized it.
For earlier uses of the phrase see William Safire, Safires Political Dictionary, pp. 33940 (1978), and Bartletts Familiar Quotations, 15th ed., p. 746, no. 9 (1980).
