  Barbara McClintock - Wikipedia, the free encyclopedia
McClintock received her PhD in botany from Cornell University in 1927, where she was a leader in the development of maize cytogenetics; the field remained the focus of her research for the rest of her career.
McClintock's research became well understood in the 1960s and 1970s, as researchers demonstrated the mechanisms of genetic change and genetic regulation that she had demonstrated in her maize research in the 1940s and 1950s.

 Barbara McClintock
McClintock was known as a maverick in the field of biology, often taking unorthodox views on the mechanisms of evolution, genetic regulation and development.
Though McClintock’s discovery of genetic transposition occurred between the 1920’s and 1950’s, her radical ideas were not well received by a scientific community that had spent the last fifty years ridding biology of every last vestige of teleology and vitalism.
When Barbara McClintock died in 1992, one of her obituaries suggested that she might well be ranked as the greatest figure in biology in the 20th century.

Barbara described an incident from childhood in which a neighbor chided her for playing boys' games in the street, telling her it was time for her to learn to do the things that girls do.
McClintock was deeply frustrated by her failure to communicate, but her fascination with the unfolding story of transposition was sufficient to keep her working at the highest level of physical and mental intensity she could sustain.
McClintock spent the winters of 1958 and 1960 in Central and South America, fascinated by the emerging realization that the spread of maize through the region could be tracked by the chromosome constitution of the indigenous populations.

After leaving the University of Missouri in 1941, McClintock joined the group of geneticists at Cold Spring Harbor, where she obtained the continuing financial support of the Carnegie Institution of Washington.
It was at Cold Spring Harbor that she made her discovery of genetic transposition, the moving chromosomal parts being later called "transposons" or "jumping genes." Working with the more complicated maize plant, McClintock had identified these genetic elements twenty years ahead of the molecular biologists who were working with far simpler life forms.
In the last quarter of her life, McClintock was honored with many awards and honorary degrees acknowledging the great importance of her work.
