You mean plagiarized it?
Franklin's experimental data wasn't the only key experimental data, but it was pivotal.
Franklin could have elucidated the structure of DNA herself, but she was working on other problems.
Watson and Crick were head's deep in the problem and were building stick figure models of all the atoms and bonds. They synthesized the collection of experimental measurements they had to correct and confirm their model.
At the time, scientists already suspected a corkscrew structure but there was disagreement between what that looked like or whether it was double or triple helixed.
Franklin's key experiments resulted in the Photograph 51 that almost single-handedly proved the structure. Before Franklin could publish her data, Wilkins—without the consent or knowledge of Franklin—took that photo and showed Watson. Watson later stated that his mouth dropped when he saw the photo. It proved to him the double helix structure and that guided the rest of their modeling/work. At that point they knew what they were proving. Two months later they'd advanced their model far enough and rushed to publication before Franklin could be credited with her own work
Not only did they use Franklin's work without her consent, not only did they not credit her, but they even belittled her in their books and talks. They even referred to her as "Rosy", a name she never used herself.
> she didn't realize its significance or implication.
That does not change the fact that they plagiarized and cheated. They could have collaborated with her and/or credited her
The man just died and it's as if you're trying to pry the Nobel Prize from him.
Franklin didn't know what she had. If she did, she would have been working on it.
In a moment of supreme clarity, the universe revealed itself. Watson and Crick knew immediately the photo would cut down their search space from alternative structures. They still had work to do, because the Angstrom length data is not a model by itself. It just constrained the geometry for the bonds and electrochemistry.
Wilkins was "second-in-command" to Randall, developed the DNA structure project, and convinced Randall to assign more people to work on it. Randall then hired Franklin, reassigned Gosling, the graduate student who had been working with Wilkins, to Franklin, and told Franklin that Wilkins would simply be handing over his data to her and that she would subsequently have full ownership of the project. Randall didn't tell Wilkins any of this of course, so a lot of hard feelings developed between Franklin and him. The situation got worse when Wilkins tried to get sample from external collaborators to continue working on the project himself and Randall forced him to hand over one of the samples to Franklin. Franklin finally got sick of Randall herself and left, leaving Randall to turn over all the data to Wilkins, who then went to talk about his pet research interest with Crick, a personal friend of his. Wilkins then recused himself from Crick's paper, feeling he hadn't contributed enough to it. He also worried publicly to others that maybe he had been unkind and driven Franklin out, having minimal insight into Randall's tactics, which are unfortunately common in the field. When they're being used on you by someone skilled in them, it's often hard to realize, and you end up being resentful of the person you're being pitted against until one of you leaves and you suddenly have clarity because the stress of the situation is suddenly reduced.
When men have had their scientific advances plagiarised, stolen, claimed from them in the same quantity as non-men, sure, but that's like saying "you're complaining that I stole a million pounds but they stole a can of coke!" Nonsense whataboutism.
(Bonus points if you know even 3 of those without looking them up)
Marion Donovan appears to have invented a "diaper cover" among other things, her patent then being ignored by several companies. Unfortunate, but I've never heard of whoever supposedly stole credit for that ground-breaking invention either, so it hardly seems relevant. I'd hope in the age of Ali Express and Temu that I don't need to point out how often men's patents get ignored.
I had heard of Nettie Stevens. Her work was not stolen, she published after Edmund Beecher Wilson.
Vera Rubin presented the very controversial theory of dark matter. Given that she worked closely with a male collaborator, Kent Ford, who co-authored many of her papers, it seems more likely that their work was overlooked due to initial resistance to the theory itself.
Lise Meitner was a Jew in Nazi Germany.
Alice Ball's work seems to have been stolen after she died in isolation in a leprosy colony. I'd never heard of Arthur Dean either.
I'll stop there as this will take forever otherwise. What you have listed seem to be extremely tenuous as evidence of gender bias - one can quite easily hop on Google and find plenty of examples of stolen inventions, from automatic windscreen wipers to Facebook.
If anything though I think the real problem is actually being inverted. At the time when women began pushing or being pushed into industry and academia, why did we value industry and academia over what the women were doing at the time? Caring for children seems pretty important, and outsourcing that to under-resourced strangers and in many cases foreigners as we do today is quite odd when you think about it.
