Barbara McClintock was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock received her PhD in botany from Cornell University in 1927. There she started her career as the leader in the development of maize cytogenetics, the focus of her research for the rest of her life. From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis—a mechanism by which chromosomes exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of genetic information.

About Barbara McClintock
Winner of the 1983 Nobel Prize in Physiology or Medicine for her study in genetic elements and genetic regulation. She was the first woman to win that prize unshared and she was elected a member of the National Academy of Sciences in 1944.
She attended Cornell University, where she studied botany.
A character in the book The Marriage Plot by Jeffrey Eugenides was loosely based off her.
She has three siblings.
She was influenced by Issac Newton.
