#4: Rosalind Franklin
In this case, the answer to our question might be just a little bit more obvious… Cough cough… Gender. This wouldn’t be the first instance of a woman’s work being overlooked and the same innovation being credited to a male competitor, and it most certainly wasn’t the last instance either.
It was only a year later, in 1953, that two men, Watson and Crick, published an article claiming to prove the double helix theory. I can only imagine what poor Rosalind must have been feeling when she received her monthly copy of the “Nature” Journal and started reading the articles.
