Barbara McClintock: March 17

Barbara_McClintock was awarded the 1983 Nobel Prize in Physiology or Medicine for the discovery of genetic transposition. She is the only woman to receive an unshared Nobel Prize in that category. She developed theories to explain the suppression and expression of genetic information from one generation of maize plants to the next. Due to skepticism of her research and its implications, she stopped publishing her data in 1953. McClintock’s research became well understood in the 1960s and 1970s, as other scientists confirmed the mechanisms of genetic change and genetic regulation that she had demonstrated in her maize research in the 1940s and 1950s.
