Watson and Crick are notorious for having secretly accessed and used Rosalind Elsie Franklin's personal x-ray images (of DNA) while she was not in the lab.
To me, Franklin is the real hero in discovering the DNA's structure, and she should have received the Nobel prize (50%), perhaps jointly with Watson (25%) and Crick (25%).
Objective scientific research means: never let your personal prejudice or ideology clout your own search for truth. The fact that Watson and Crick did not even mention or cite Franklin's article, which ironically even appeared in the same issue of _Nature_ as Watson and Crick's paper, is most dishonorable and dishonest.
