A story that remained secret for 50 years
This 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.
This site originates with and is maintained by Debbie Anderson in Dayton, Ohio. 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. It is an outgrowth of my own efforts to learn more about this story and a desire to share what I have learned — I ask visitors’ bear this in mind when links or pages disappear or become mangled in the vagaries of Php and generated code.
Thanks for learning about a part of Dayton’s, and the nation’s, history.
Government-funded DETERlab was built to bring established scientific principles to the field of cybersecurity in hopes of preventing successful cyberattacks.
