# NSA Cryptologic History Symposium

HomeHistoryCryptologic HistoryCryptologic History Symposium

NSA's Center for Cryptologic History (CCH) and the National Cryptologic Foundation (NCF) co-host the Cryptologic History Symposium. Since 1990, the Cryptologic History Symposium has served as an opportunity to present historical scholarship found in unclassified and declassified cryptologic records and engage in discussion about their significance to history. The event is an occasion for historians and those interested in history to gather for reflection and debate on relevant and important topics from the cryptologic past. Regular speakers include historians from CCH, the Intelligence Community, the defense establishment, the military services, scholars from American and international academic institutions, veterans of the cryptologic profession, graduate and undergraduate students, and noted authors. Past symposia have featured scholarship that set out new ways to consider our cryptologic heritage. The conference provides many opportunities to interact with leading historians and other experts. The mix of practitioners, scholars, and interested observers guarantees a lively debate that promotes an enhanced appreciation for past events.**Next Symposium – Date TBD**Questions may be directed to cchevents@nsa.gov**The 18th Cryptologic History Symposium “Icons and Innovation”** occurred virtually on May 11-12, 2022.Sketchnotes from the following sessions are now available:  Session 1: Keynote Address by former DIRNSA, Admiral Bobby R.
