The mission of this site is to tell the story of hundreds of people who worked at the United States Naval Computing Machine Laboratory, a top secret project in Dayton during World War Two. These people kept their secret for over fifty years.
Please take a look–there are hundreds of pages of declassified documents, rosters of personnel, photographs and more. I have added a new bibliography page brought up to date to include burgeoning information about cryptography on the web.
This site originates with and is maintained by Debbie Anderson in Dayton, Ohio. This site is an outgrowth of my own efforts to learn more about this story and a desire to share what I have learned. It also is a resource for documentation behind the documentary Dayton Codebreakers.
I am grateful to the Archive Center at Dayton History, the Wenger Command Display in Pensacola, Florida, friends at the NSA Cryptologic History Center and the National Cryptologic Museum, and the many veterans–WAVES and sailors– who have been so generous over the years for a share of the photographs presented here.
Thanks for learning about a part of Dayton’s, and the nation’s, history.
