The coordinator of this web site is Deborah (Debbie) Anderson, daughter of Joseph Desch, Research Director for the U.S.N.C.M.L. I am in Dayton, Ohio, and work on this site as a way to share the information I’ve amassed with the public. I can be reached by email at this link. Please add a specific subject line, to make it distinguishable from spam.
The sources of the material on this site are varied, as you’d expect in a site this large:
1) Introductions to each section, and sometimes to individual pages, are written by me. Use by permission.
2) Most documents are from the National Archives (NARA2, College Park, Maryland) and are in public domain (no permission needed).
3) Articles from the NSA are also in the public domain.
4) Specific items, such as the WAVES ID badges, are used by permission of Dayton History. You should always write to ask before using.
5) Some few items, such as the page “Build a Bombe” are from published sources and are acknowledged as such.
I am not accepting speaking engagements as I have for more than 30 years. This web site and the documentary Dayton Codebreakers contain most of the material I use.
For information about Dayton Codebreakers, the documentary produced by Aileen LeBlanc and Debbie Anderson, contact Aileen Leblanc at aileenleblanc@hotmail.com.
Much of the information and many of the photos used in this web site are from the Archive Center at Dayton History. Information about Dayton History can be found by visiting their web site of www.daytonhistory.org/.
The repository of the best primary source information about the USNCML remains the National Archives and Record Administration 2 in College Park, Maryland.
In April, 2004 The Secret in Building 26 written by Colin Burke and Jim DeBrosse was published. This book was the product of years of research by Burke, and material gathered by DeBrosse when writing the Dayton Daily News series. That book remains the sole and best narrative of the cryptographic work in Dayton in WW2.
