## Summary
Discovered that sex is determined by chromosomes, not environment. Started science late (PhD at 39 after years of teaching). Meticulous microscopist who studied mealworm chromosomes with extraordinary patience. Wilson got much of the credit during her lifetime. Died of breast cancer at 50, just as her work was being confirmed. Quiet, careful, right.
