Born
Nettie Stevens, working at Bryn Mawr, showed in 1905 from studies of mealworms that sex is determined by particular chromosomes, the X and Y system. Edmund Beecher Wilson reached a similar conclusion independently, and textbooks long credited him or Thomas Hunt Morgan. She died in 1912, before her work was widely attributed to her.
