Roy. 8vo., First Edition, with photographs, facsimiles and maps in the text; original photographic wrappers, wire-stitched as issued, a near fine copy. The first Enigma Symposium, held at the Swan hotel in Bedford. The last to date was held in 2003. Scarce.
3 vols., 8vo., First Edition, with 46 plates on 24, very numerous photographs, facsimiles, maps and diagrams (many full-page) in the text and front and rear endpaper maps (first two volumes) and front endpaper chart (third volume); green cloth, gilt backs, a near fine set in unclipped dustwrapper. FIRST AND THIRD VOLUMES SIGNED BY THE AUTHOR ON TITLE. The trilogy comprises Spies of the Airwaves (1989), Knowledge strengthens the Arm (1991) and Enigma and its Achilles Heel (1992). Skillen's comprehensive and detailed history of the Y Services is a remarkable personal achievement. The first volume describes how Y provided Allied commanders with regular and accurate intelligence through wireless intercepts. The second volume concentrates on the background to the training of intelligence officers (including a fascinating personal diary of signals exercises and details of the three Germans who made Y victory possible). The final volume stresses the intricacies of the interplay between Y and ULTRA, some elements of which are lost even now in classified secrecy. Privately printed in relatively small numbers, individual volumes are increasingly scarce. Together they comprise an outstanding contribution to the understanding of Y, ULTRA and Enigma throughout WWII. COMPLETE SETS ARE VERY SCARCE.

"Now, for the first time, the insider's view of the Enigma story and other clandestine operations is revealed by Gordon Welchman, a top British mathematician who was largely responsible for the crucial achievements at Bletchley Park in the first months of WWII. Goes beyond Bletchley to show how the lessons learned from Germany's errors in using the Enigma codes can - and must - be applied to the use of military communications today." - dust jacket.

Shulman spent twenty-five years researching this work and wrote it with librarians, students of cryptography, and book collectors in mind. An introduction preceeds the following six sections: works relating directly to ciphers from 1518 to 1976, chronological list of works relating indirectly to cryptography, chronological list of manuscripts, alphabetical index of authors and translators, chronological list of patents on cryptographic devices from 1874 through 1953, sample list of books on cryptography written in languages other than English. From the library of Philip Mills Arnold whose bookplate is mounted inside front board. Arnold, a student of semeiology, explored the history of communication, from efforts to relate through universal languages and alphabets, to systems to conceal, specifically, codes and ciphers. A Semeiology collection named in his honor is maintained at Washington University. In his professional life Arnold spent nearly forty years with Phillips Petroleum, retiring in 1976 as V.P. of Research and Development with 22 patents to his name. Moderate wear. Occasional light pencil marginalia. A sound association copy of this invaluable cryptographic reference. Book
