Announcing the
Ed Fouhy Distinguished Speaker Series

EFDSS Logo We are proud to announce the Ed Fouhy Distinguished Speaker Series,a program which will engage the community in exploring significant and thought-provoking topics.

As a communications professional Ed Fouhy brought the world and its stories to the American public. Ed Fouhy As a CMMC volunteer and museum docent, Ed wrote and produced two videos explaining the importance of wireless radio communications to the rescue of Titanic survivors and the outcome of the Battle of the Atlantic during WWII. Through a limited schedule of special presentations the Ed Fouhy Distinguished Speaker Series has been established to promote knowledge and understanding of history and world events, with a special focus on the science and development of communications technology and its profound effect on our lives.

On October 15, 2015 our inaugural distinguished speaker was Professor Thomas Perera, PhD. In a followup to his riveting presentation at our May 9 Annual Meeting, Dr. Perera presented "Clandestine Radio Operations In World War II". The Ed Fouhy Distinguished Speaker Series and Dr. Perera were introduced by Morton Dean, formerly of CBS and ABC News.

Look for the next program in the Ed Fouhy Distinguished Speaker Series coming in April 2016. Details will be announced in the 1st quarter.

CMMC Tells Chatham's World War II Story

Chatham’s top-secret role in defeating the Germans during World War II came alive this summer as we remembered the 70th anniversary of the war’s end.

Stalking the U-Boats: Chatham Radio 1942-1945 was the theme for special exhibits, and the Thursday evening Summer Speaker Series also followed the World War II theme.

The museum remembered The Navy’s "Station C” which located marauding German U-Boats and intercepted their Enigma-encrypted radio messages, which was a key to winning The Battle Of The Atlantic.

A new interactive display featured both a real German Enigma-cypher machine and an electronic Enigma simulator, which allowed visitors to encrypt and decipher their own messages. The Enigma was a central figure in last year’s Oscar-nominated The Imitation Game.

Other interactive exhibits, including learning Morse code and tracing a ship-to-shore telegram through all of its steps, filled the museum, which traces 100 years of wireless communications.

Annual Meeting - Secrets of the Enigma - May 9

The whole story behind the breaking of German secret codes during the Second World War was at the heart of Dr. Thomas Perera's keynote speech at CMMC's annual meeting on Saturday May 9.

Dr. Thomas Perera, Ph.D., is Professor Emeritus at Montclair State University in New Jersey. He is the author of Inside ENIGMA--the Secrets of the Enigma and Other Cipher Machines, and is a world-renowned curator and collector of Enigma machines.

Prof Perera

Dr. Perera described the German U-boat threat to the Allies in World War II, and the role of the Enigma Machine in sending encrypted instructions to the U-boats. He explained how the messages were eventually intercepted (here in Chatham) and deciphered, hastening the defeat of the U-boat fleet and the end of the war.

CMMC and the Chatham Orpheum bring The Imitation Game "Home"

Thanks to CMMC, anyone who attended showings of The Imitation Game at the Orpheum Theater received additional insight into the secret German code operations of World War II, and how the U.S. Navy top-secret “Station C” on Ryders Cove played its part in the defeat of the Nazis.

The movie explains how the Nazi Enigma codes were broken, enabling the Allies to understand secret German military messages. CMMC will provide a short video [click below to see the video] for each showing of The Imitation Game - depicting how the Enigma Cipher Machine worked.

Enigma Machine

This authentic Enigma cipher machine is part of CMMC’s Marconi-RCA Wireless Museum 2015 salute to Chatham Radio’s classified wartime role. The museum, located within the aforementioned Station C operations building, opens for the summer season on Chatham’s History Weekend, June 20. It will feature expanded exhibits about the Navy Years including this Enigma, a hands-on Enigma-based coding and encryption experience, special events and presentations by WWII experts.

Chatham Navy Radio played a significant role in defeating the Germans during the World War II Battle of the Atlantic by intercepting Enigma-encrypted wireless messages between German headquarters and its ships at sea, passing the intercepts on to Washington, DC for decoding. In addition, as the control station for the east-coast direction-finding network, Station C directed the search for telltale radio signals that allowed enemy vessels to be located and tracked.

The Marconi-RCA National Register District is a 13 acre site that complements the modest, finely crafted buildings, built in 1914, common in the early 20th century. Full exterior Historic Restoration of all 10 buildings on the site had been completed by the Town of Chatham in 2008. Interior renovations, including full ADA compliance, were completed by CMMC, in the Operating Building, ("Marconi-RCA Wireless Museum") in 2010 and the former Hotel Nautilus ("Education Center") in 2014, Recent exterior renovations by the Town of Chatham added ADA access and landscaping.
