Other late crypto experts, like Jack Levine, Louis Kruh, David Hamer, and David Shulman have left behind impressive collections, too. They are goldmines for crypto history enthusiasts like me.
However, no source I know mentions an Albert C. Leighton collection.
At HistoCrypt in Uppsala, Craig Bauer, the editor-in-chief of Cryptologia and author of the book Unsolved!, told me that he had tried to find out the whereabouts of Leighton’s files, too – but to no avail.
Can my readers help?
Perhaps, a reader can help in this situation. Does anybody know where and when Albert C. Leighton died? Did he have children I can contact? Did he or his descendants donate his research material (which is probably for the most part not crypto-related) to an archive or library? And do you know other crypto-related publications of Albert C. Leighton? If so, please let me know.
