Edmund Beecher Wilson was a pioneering American zoologist and geneticist. He wrote one of the most influential textbooks in modern biology, The Cell in Development and Inheritance. He discovered the chromosomal XY sex-determination system in 1905. Nettie Stevens independently made the same discovery the same year and published shortly thereafter.
