Throughout her career, Barbara McClintock studied the cytogenetics of maize, making discoveries so far beyond the understanding of the time that other scientists essentially ignored her work for more than a decade. But she persisted, trusting herself and the evidence under her microscope.
Jun 12, 2024 · Barbara McClintock (born June 16, 1902, Hartford, Connecticut, U.S.—died September 2, 1992, Huntington, New York) was an American scientist whose discovery in the 1940s and ’50s of mobile genetic elements, or “ jumping genes,” won her the Nobel Prize for Physiology or Medicine in 1983.
Awards and recognition for her contributions to the field followed, including the Nobel Prize in Physiology or Medicine, awarded to her in 1983 for the discovery of genetic transposition; as of 2023, she remains the only woman who has received an unshared Nobel Prize in that category.

Barbara McClintock was a pioneer in the field of cytogenetics, and she left a lasting legacy of superb experimental inquiry. McClintock’s breeding experiments with maize are particularly...
Lived 1902 – 1992. Barbara McClintock made a number of groundbreaking discoveries in genetics. She demonstrated the phenomenon of chromosomal crossover, which increases genetic variation in species.
Dec 10, 2012 · In the late 1940s, Barbara McClintock challenged existing concepts of what genes were capable of when she discovered that some genes could be mobile. Her studies of chromosome breakage in maize led her to discover a chromosome-breaking locus that could change its position within a chromosome.
Sep 2, 1992 · Barbara McClintock was a Nobel prize-winning plant geneticist, whose multiple discoveries in maize have changed our understanding of genetics.
