I went to The Eagle pub in Cambridge last night with Drs. Hull and Fisher. Despite numerous signs to the contrary this is not where Crick and Watson discovered DNA, but where it was announced over lunch that they had "discovered the secret of life" - the structure of DNA. That was in 1953. We'd known of DNA for decades by then.
How would you discover DNA in a pub? Inside a steak and kidney pie? Fortunately the blue plaque outside was more accurate.
