Dundee Society

Source: Wikipedia, the free encyclopedia.

The Dundee Society was a society of graduates of CA-400, a

Zendian Problem (a practical exercise in traffic analysis and cryptanalysis).[1] The class was held once a year, and new members were inducted into the Society upon completion of the class. The Society was founded in the mid-1950s and continued on after Callimahos' retirement from NSA in 1976. The last CA-400 class was held at NSA in 1979, formally closing the society's membership rolls.[2]

Keiller's Dundee marmalade jar

The society took its name from an empty jar of

underlying government agency's name for security reasons, he spotted the ceramic Dundee jar and decided to use "The Dundee Society" as the cover name for the luncheon reservation.[2] CA-400 students were presented with ceramic Dundee Marmalade jars at the close of the course as part of the induction ceremony into the Dundee Society. When Dundee switched from ceramic to glass jars, Callimahos would still present graduates with ceramic Dundee jars, but the jars were then collected back up for use in next year's induction ceremony, and members were "encouraged" to seek out Dundee jars for their own collections if they wished to have a permanent token of induction.[2]
