This week we interview Betsy Smoot, an intelligence historian interested in early twentieth-century cryptology and communications. She retired from the Center for Cryptologic History of the National Security Agency in 2017, and she has published articles in Cryptologia and Intelligence and National Security.  Her book, Parker Hitt: The Father of American Military Crytology, was published by the University Press of Kentucky in March 2022. Betsy Smoot was interviewed by fellow BIO member Jennifer Skoog.
