Warwick Estevam Kerr, Brazilian geneticist, entomologist, and engineer
Warwick Estevam Kerr (9 September 1922 – 15 September 2018) was a Brazilian agricultural engineer, geneticist, entomologist, professor and scientific leader, notable for his discoveries in the genetics and sex determination of bees. The Africanized bee in the western hemisphere is directly descended from 26 Tanzanian queen bees (A. m. scutellata) accidentally released by a replacement bee-keeper in 1957 in Rio Claro, São Paulo in the southeast of Brazil from hives operated by Kerr, who had interbred honey bees from Europe and southern Africa.
