In September 1956, a telephone cable called TAT-1 was laid under the Atlantic Ocean, making high-quality transatlantic phone calls possible for the first time.

Eight months later in May 1957, 1,000 people squeezed into St Pancras Town Hall in London to listen to a transatlantic concert.

The person performing, Paul Robeson, was a globally renowned singer, but he’d been banned from travelling outside the USA. So, he made use of the new transatlantic telephone line to perform to his fans in the UK.

Ben Henderson speaks to John Liffen, who curated an exhibition on TAT-1 and the concert at the Science Museum in London.
