William F. Friedman Papers
William Frederick Friedman (1891-1969) was an American cryptologist, considered by experts to be the greatest of all time. The papers consist of general correspondence (1942-1969); government service papers; Congressional Relief Bill material; patents; speeches and writing; numerically indexed papers; and photographs. Correspondence with cryptographers of national and international renown can also be found. Friedman’s private cryptological work on such subjects as the Voynich manuscripts, codes and ciphers of ancient cultures, and the authorship of Shakespeare’s work are also treated in the collection. Also to be found is a personal library of 110 linear feet, 18 linear feet of vertical file material, and 12 linear feet of artifacts.
