To most patrons, this is a fairly typical Cambridge pub – crammed full of punters on a Friday night and popular with students and locals alike. However, it’s also the place where James D Watson and Francis Crick announced that they had “found the secret of life” in 1953.

The Cavendish laboratory in which the two scientists worked stands nearby (although it is now used for other purposes and the Cavendish has been moved further away from the city centre) and the Eagle was a popular lunchtime destination for staff working there.

On 28th February, Francis Crick arrived for lunch and announced a proposal that was to change our understanding of the world — the double helix structure of DNA, which eventually led to the pair, plus Maurice Wilkins, receiving the Nobel Prize in 1962.

Today, visitors can enjoy a pub lunch in the same rooms, also admiring the graffiti scrawled by pilots in the RAF Bar (at the rear of the pub) during World War II.
