If there were hundreds of people trying to get there, and another got there before Watson and Crick, would they deserve fame and Watson and Crick the equivalent obscurity? Its not that Watson and Crick weren't brilliant and driven - it's that they were part of a larger collective movement that is undervalued. And I would argue that their contributions were dramatically overvalued partly because they were immersed in a culture which overvalues, and motivated them to overvalue, a very heroic "great man" narrative.
If they hadn't "discovered" the structure of DNA, how long do you think it would've been before someone else did?
