Barbara McClintock (1902-1992) 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. She produced the first genetic map for maize, linking regions of the chromosome to physical traits.

She was recognized among the best in the field, awarded prestigious fellowships, and elected a member of the National Academy of Sciences in 1944.

"SHE CHANGED STEM" poster series feature women working in the field of STEM that revolutionized science with their hard work and brilliant findings.

Half of the profits from the sale of "SHE CHANGED STEM" posters and digital files will be donated every week to a different non-profit organization promoting gender equality in STEM fields, The other half will allow us to print extra posters to donate to Schools and educational institutions.

You can buy the printed posters individually from this store in JPG format to print it yourself (3600 x 2700 pixels, up to 24" x 18", 150 DPI)
