For over a century, GCHQ has been at the forefront of national security. Timandra Harkness delves into the secretive world of the intelligence agency past and present with a senior GCHQ representative and curator Science Museum curator Elizabeth Bruton, who has been unearthing treasures from the archive for the Science Museum’s Group’s Top Secret: From ciphers to cyber security exhibition. Uncovering the rich personal and technological stories that have underpinned secret communications over the past century, we explore the intrigue of espionage, consider the major challenges and opportunities facing those working at the heart of the nation’s security today and examine the trends that could shape tomorrow.

The Science Industry Musuem are hosting the Top Secret exhibition from 19 May – 31 August 2021.

This event will be live-streamed for free and available on-demand via the CheltSciFest Player. To register, click here.


Dr Elizabeth Bruton is Curator of Technology and Engineering at the Science Museum, London and curated the ‘Top Secret: From ciphers to cyber security’ exhibition at the Science Museum, London and now at the Science & Industry Museum, Manchester, both part of the Science Museum Group. ‘Top Secret’ explores over a century’s worth of communications intelligence through hand-written documents, declassified files and previously unseen artefacts from the Science Museum Group’s and GCHQ’s historic collections.
