National Security Agency’s National Cryptologic Museum 

The Germans' extensive use of a cipher machine that they believed was unbreakable led to an Allied cryptanalytic success story.  Many have heard of the Engima, the German workhorse for making their tactical communications secret.  What they did not know is that the Allies were reading those messages throughout WWII.  Many have also heard that the British broke the encryption system.  Learn the real story behind solving Germany's Enigma puzzle, led first by the Polish and enhanced by the Americans.

Presented via Zoom.  General admission $10; Members free.  

Information and Tickets

A Landmark Date In Radio History

Following World War I, the newly-formed Radio Corporation of America (RCA) acquired the assets of the Marconi Wireless Telegraph Company of America, including its unfinished installations at Chatham and Marion, Massachusetts.  RCA installed state-of-the-art equipment manufactured by U.S. industrial giant General Electric, and trans-Atlantic station WSO went on the air on May 17, 1920.  Come explore our newest exhibit, “Chatham On The Air."


Chatham Marconi Maritime Center introduces “Radio to the Rescue” 


 At the turn of the 20th century, radio communication ended the isolation of mariners at sea.  Valuable lessons learned from early sea disasters on up to the present day help keep people safe today and have saved countless lives.

Enjoy a series of special events, fascinating speakers and new exhibits at the Marconi-RCA Wireless Museum.
