Lieutenant Commander Eric, Nave

Eric Nave, an Australian naval officer, was a highly skilled decoder. He was with the Far East Combined Bureau (FECB) where, in late 1939, he began to break the difficult Japanese Naval code JN-25. It has been said that the code remained unreadable by the Americans until 1942 and that Nave reported messages sent using it in late 1941, before the Hawaii Operation was undertaken. If that is true, it indicates a failure of British and American espionage liaison, either through neglect, incompetence or design. It is also said that OP-20-G, the American unit, had in part broken JN-25 in early 1941. Nave served in intelligence for 42 years. He was awarded the Order of the British Empire in 1946.
