In Depth

There are many documented sources of information regarding the Dayton code breaking effort. The most dramatic and detailed are at the National Archives at College Park, Maryland. The library at the National Cryptologic Museum is building an impressive collection of books and documents. However, some documents remain in the NCR Archive at Dayton History, and there is much research yet to be done. The list below contains links to documents and information available at this site.


  • Transcription of Report written by Capt. Ralph I. Meader to the Vice Chief, Naval Operations, January 1949
  • Commendation for USNCM by J. N. Wenger, Jan. 1945
