the original three dimensional model of the DNA double helix by watson and crick!

Found in the Science Museum. This exact model was used by Francis Crick and James Watson (with a lot of help by Rosalind Franklin, whose x-ray crystallography images of DNA they used) to propose the double helix model of DNA. This paved the way for modern medicine, molecular genetics, blah blah blah, exciting stuff. Apparently after Watson and Crick finished the proposal they ran over to the local pub in Cambridge and started screaming their heads off about how they had discovered “the secret of life”. Here they are with the exact model, about 60 years ago.
