About the event

The Great Seal Bug – The Full History
The premiere of "The Thing" - a film uncovering the story of the Great Seal bug - one of the first passive covert listening devices.

Join us at The National Museum of Computing for the premiere of "The Thing" - a captivating film that uncovers the complete history of one of history's most astonishing espionage incidents.
The film delves into the incredible story of the Great Seal bug, starting with the birth of the inventor in 1886, his formative years during the Bolshevik Revolution, and his time in the USA. It explores the influence of the Cambridge Spies and the bug's discovery in 1952. In more contemporary times, "The Thing" also investigates the work of Peter Wright and Tony Sale, detailing their efforts to understand and counter this ingenious device.
The film vividly portrays the story of one of the first passive covert listening devices against the backdrop of H Block, Bletchley Park, adding a unique dimension to this tale of technological espionage.
Tickets also include day admission to view the world's largest collection of functional historic computers, including the Bombe and Colossus - the world's first electronic, digital computer.
Event Schedule:
-Refreshments on arrival
-Screening of "The Thing"
-Q&A with John Little, compered by John Carter
About the Speaker:
John Little's connection to Bletchley Park and counter-surveillance is truly unique. His first visit to Bletchley Park was in 1962 as a Post Office Telephone Engineer. He later joined the Foreign and Commonwealth Office, working in Hut 3, Bletchley Park (Diplomatic Wireless Service). In 1978, he left the FCO to start a company specialising in counter surveillance – de-bugging. His office was moved to H Block approximately 20 years ago, and later to E Block.
