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."

Battle of the Atlantic - The American Theatre of WWII


December 3 at 7:00 PM

Joseph Hoyt

NOAA National Maritime Heritage Program Coordinator







From January through July of 1942, the U.S. east coast became the focus of the Battle of the Atlantic.  German U-boats operated within sight of shore sinking allied ships and merchant vessels by the hundreds.  This was the closest theatre of war to the continental U.S. yet remains underrepresented in history.  The presentation will focus on activities that took place off the east coast, in particular North Carolina, with an emphasis on the technological and environmental parameters that influenced the landscape of this naval battlefield. 

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