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.


“One of the things that I really strongly believe in is that we need to have more girls interested in math, science, and engineering. We’ve got half the population that is way underrepresented in those fields and that means that we’ve got a whole bunch of talent…not being encouraged the way they need to.”. Former President Barack Obama, 2013

Today, women hold only 27 percent of the jobs in computer science, and 14 percent in engineering. One reason is the lack of female role models in STEM fields to encourage more girls to study math and science.

"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.

Now more than ever is time to take action and honor women's legacy in the fields of Science, Technology, Engineering and Math.

These are matte, museum-quality posters are printed on durable, archival paper.
