On the 50th anniversary of the discovery of the double helix structure of DNA spare a thought for Rosalind Franklin the chemist who produced the x ray cystallography data (most famously her Photo 51 showing the x-ray diffraction of wet DNA) that supported the double helix structure and which was shown to Watson and Crick without her knowledge by her collaborator Wilkins . Franklin, who died before the Nobel prize was awarded, never received credit for her contribution and was on the receiving end of Watson’s sexism in his book The Double Helix Sexism which despite being fundamentally unscientific is unfortunately all too common in the history of science. But with a new book lets hope in this 50th anniversary year that Rosalind Franklin gets her contribution to this great discovery recognised.
