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
