Born in 1861, Nettie Stevens received her PhD in 1903. She went on to discover sex chromosomes in mealworms. Until then, it was believed that the mother or environment determined males & females.

But... Edmund Beecher Wilson published first. He may have seen Stevens' results & also didn't quite get everything right.

Stevens' work had the correct conclusion, but Wilson is most often credited with this discovery.

Just wanted to say thank you for sharing these. So many women’s achievements have been overshadowed or lost to history; I really appreciate learning more about their work.
