Women in Science Wednesday! Barbara McClintock used this microscope in the 1940s and 1950s to study the genetic elements of maize. This research helped her develop the theory of genetic transposition, the process by which segments of DNA (or "jumping genes") move from one location on a chromosome to another.
When Dr. McClintock published her results, she met with skepticism from many fellow geneticists; her groundbreaking research would find practical application only years later. However, in 1983, she was awarded the Nobel Prize for her work. McClintock's life exemplifies how scientific innovation often depends on disinterested research.
This portrait of McClintock is in the collection of the Smithsonian Archives.
McClintock's story will be featured in "American Enterprise," opening in July. ‪‬ #WomensHistory #WHM #BusinessHistory #Groundbreaker
