Google is honoring Nettie Stevens today; did she ever get married and have children? Her wiki entry makes no mention of either. Did her mother die of breast cancer? Did her not having children contribute to her getting breast cancer? A New Englander - a Yankee? Did she displace a man from scientific research? Did she ever attempt to assume authority over men? How much of a ideological feminist was she?
Nettie Stevens discovered XY sex chromosomes. She didn't get credit because she had two X’s.
