Eunice Newton Foote was an American scientist, inventor, and advocate for women’s rights. She is best known for her pioneering work in the mid-19th century, where she became the first scientist to propose the idea of the greenhouse effect. Born in Connecticut and educated at the Troy Female Seminary and the Rensselaer School, Foote was a product of her time, actively participating in movements such as abolitionism, temperance, and women’s rights.
In 1856, Foote published a groundbreaking paper demonstrating the heat-absorbing properties of carbon dioxide (CO2) and water vapor, predating similar work by John Tyndall. This marked her as the first American woman to have her scientific findings published in a physics journal. Her insights into how changing atmospheric CO2 levels could impact climate were visionary. While her experimental methods had limitations, her contributions to early climate science were instrumental, earning her recognition in the 21st century with the establishment of The Eunice Newton Foote Medal for Earth-Life Science by the American Geophysical Union.
