The Eagle and Child and the Lamb and Flag, Oxford, were regular meeting places of the Inklings, a writers' group which included J. R. R. Tolkien and C. S. Lewis. The Eagle in Cambridge is where Francis Crick interrupted patrons' lunchtime on 28 February 1953 to announce that he and James Watson had "discovered the secret of life" after they had come up with their proposal for the structure of DNA. The anecdote is related in Watson's book The Double Helix. and commemorated with a blue plaque on the outside wall.
