The Eagle pub on Bene't Street has been serving Cambridge since 1667, making it the city's second oldest pub. It began as a coaching inn. For a hundred years, from 1874 to 1974, it was the regular haunt of scientists from the nearby Cavendish Laboratory, where many of the twentieth century's most significant physics discoveries were made.

The pub's most famous moment came on 28 February 1953, when Francis Crick burst in and announced to a rather startled lunchtime crowd that he and James Watson had discovered "the secret of life": the double-helix structure of DNA. A blue plaque outside now marks the spot. Notably, a later plaque added the names of Rosalind Franklin and Maurice Wilkins, whose X-ray crystallography work was essential to the breakthrough.

VoiceMap's Cambridge tours trace this story in full, using the Eagle to examine what the discovery owed to Franklin and why, for decades, her contribution went unacknowledged.
