Watson is famous for his 1953 work with Crick where they proposed a modification of Linus Pauling's helix model of DNA. Their basis was some unpublished experimental work taken from Rosalind Franklin at a rival lab. When Pauling saw their papers, he corrected their modification and found the chemical structure of DNA.
Lynne Osman Elkin says:
One of the things I proposed last year at AAAS [the American Association for the Advancement of Science annual meeting] is that I think it should be called the Watson-Crick-Franklin structure. As far as I'm concerned, she was a de facto collaborator. Maybe she didn't give them her information directly. But every time they hit a stumbling point, it was her information that they got from Wilkins that straightened it out.Watson was promoting a new edition of his 1968 book that brags about stealing Franklin's data and unpublished theories, and then tricking her into publishing her paper after the famous Watson-Crick paper. The public was thereby fooled into thinking that her work was done to confirm the Watson-Crick model, when it was actually the chief inspiration for the model.
In the Friday interview, Watson continued to badmouth her, and to refuse to give her credit for what she did. He even boasted that she died without knowing how he and Crick had cheated her.
Watson also claimed to not remember saying that Africans are stupid, and then mumbled something about not wanting to be quoted. His answers to other questions, such as about what defines good science, were surprisingly lame.
I have written extensively about how Einstein has been over-credited for relativity, thereby fueling speculation about how credit relates to his Jewishness. In the case of DNA, Watson, Crick, and Franklin were all atheists, and only Franklin was of Jewish descent. If there is a Jewish conspiracy to credit Jews, then Franklin should have been credited. It has been alleged that sexism was at work, but I do not see any evidence that she was mistreated because she was a woman or a Jew. It appears to me that Watson and Crick were just dishonest and greedy for the credit, and others failed to stick up for her.
