Barbara McClintock
Barbara McClintock (June 16, 1902 - September 2, 1992) was an American geneticist who discovered Transposons while seeking to explain the coloring patterns of maize (corn) seeds. Her work was overlooked for many years, because it did not fit the then-accepted models of genetics.
McClintock was born in Brooklyn, New York. She earned her B.A. and Ph.D. from Cornell University. She was awarded the Nobel Prize in Physiology or Medicine in 1983.
