vi, [2], 237, [11] pages. Illustrations. Appendix. Bibliography. Solutions. Index. Cover has some wear and soiling. This work is augmented for the first time with solutions to all cryptograms prepared by Max Katz and Geoffrey Mott-Smith. Helen Fouché Gaines (October 12, 1888 - April 2, 1940) was a member of the American Cryptogram Association and editor of the book Cryptanalysis (originally Elementary Cryptanalysis) first published in 1939. The book described the principal cryptographic systems of the 19th century and cracking methods including elementary contact analysis (cryptanalysis). Her nom was PICCOLA. Shortly after the publication of the book, she died. The material in this work drew on material compiled by members of the American Cryptogram Association. Some sections of this work are attributed to individuals other than Ms. Gaines. Thorough, systematic introduction to serious cryptography, especially strong in modern forms of cipher solution used by experts. Nihilist, grille, U. S. Army, key-phrase, multiple-alphabet, Gronsfeld, Porta, Beaufort, periodic ciphers, and more. Simple and advanced methods. 166 specimens to solve â€" with solutions.
