By 1931 the Navy had tested and discarded the double‑printer model of the Hebern Cipher Machine and had placed an order for 30 single printer Hebern Cipher Machines for service tests. An early form of “strip cipher” was introduced by the Navy as a step in the transition from codes to ciphers and to serve as an interim system until the Electric Cipher Machine could be perfected. The Army took a dim view of the Electric Cipher Machine at that time and attempted to induce the Navy to abandon it: under the circumstances “collaboration” was impossible.

This five-part series is Captain Laurance Safford’s version of pre-Pearl Harbor communication intelligence history.  This paper was prepared between 21 and 27 March, 1952.

One of the first U.S. Naval Officers to specialize in the new field of cryptology, CAPT Safford headed the newly‑established Cryptographic Research Desk in the (OPNAV) Code and Signal Section from 1924‑1925. His efforts to improve U.S. communications security aided substantially in the development of machine ciphers. During World War II he served as Assistant Director of Naval Communications for Cryptologic Research. From 1949 through 1951 was Special Assistant to the Director, Armed Forces Security Agency. In 1958 Congress awarded him $100,000 for his wartime inventions in lieu of patents. He is remembered as one of the pioneers of naval cryptology.
