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.

18881778Omaha: Ackermann Bros. & Heintze 1888. Very good. 6112pp. 16mo. Original cloth. Light wear to cloth at edges and corners; boards slightly rubbed. Contemporary ink stamp on front pastedown; slightly later bookplate on front free endpaper. Light tanning and dust soiling internally. A fascinating and unrecorded book of ciphers used in telegraphic communications by the Armour-Cudahy Packing Company "compiled exclusively for use between them and their agents and brokers." The company was founded in South Omaha adjacent to the Omaha Stockyards in 1887 by Michael Cudahy and Philip Armour. It operated for four years and became one of the "big four" packing companies in Omaha before Cudahy bought out Armour in 1891 and it became simply the Cudahy Packing Company. By the mid-20th century their plant occupied five square blocks between the stockyards and the South Omaha Terminal Railway.The present book contains thousands of code words for sales phrases types of meat weights and measures prices and other notes on shipments payments and markets. Sections are organized alphabetically -- the most basic and important code words for sales consignments and orders all begin with "A" for example. Words for times and numbers start with "B" while codes plain prices begin with "C." Words for all manner of meat products in differing amounts occupy "D" through "P." Perhaps our favorite term here is "Rescue" which translates to "Meat a little soft otherwise good." Overall an excellent document of the evidently serious world of meat packing cryptography in the late 19th century. Not in OCLC. Ackermann Bros. & Heintze unknown books
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.
