Part two of the illustrated lunchtime series Over, Under, and Across looks at the newest and most demanding way of crossing a river: going under it. Historian Tom Furber, Engagement and Learning Officer at The London Archives, shows how the struggles of Marc Brunel and his famous son led to a pioneering tunnelling technology that still underpins tunnel projects today.
Furber is also a doctoral candidate at Royal Holloway, University of London, and a fellow of the London Centre for Public History, where his research focuses on inclusive engagement in archive settings. The talk is in person only and can be enjoyed on its own, without having seen Part One.
