Who is Eunice Newton Foote? Why Google is celebrating her birthday with a doodle slideshow?

Google Doodle: Multinational tech giant Google celebrates Eunice Newton Foote’s 204th birth anniversary with an amazing slideshow doodle. She was the first scientist to conclude that some gases warmed when exposed to sunlight and that increasing amounts of carbon dioxide (CO2) would change atmospheric temperature and possibly affect the climate. This phenomenon is now known as the “greenhouse effect.”

from today #Google doodle celebrates American scientist and women’s rights activist, Eunice Newton Foote.

Foote was born on July 17, 1819 in Goshen, Connecticut, United States. She was an American scientist, inventor, and women’s rights advocate. She grew up in a time when women’s opportunities for education and scientific participation were limited, but she still followed her passion for The science. According to the official Google Doodle website, “At the time, women were widely shunned in the scientific community. Undeterred, Foote performed experiments on her behalf. After placing mercury thermometers in glass cylinders, she discovered that the cylinder containing carbon dioxide experienced the most significant warming effect of the sun. Foote was ultimately the first scientist to make the connection between rising carbon dioxide levels and warming of the atmosphere.”


In 1856, Foote conducted a series of experiments to study the effects of different gases on the absorption of heat from the sun. He filled glass cylinders with various gases, including carbon dioxide and air, and exposed them to sunlight. Foote observed that the cylinder filled with carbon dioxide retained more heat than the one filled with air. He concluded that carbon dioxide has the ability to trap heat and increase the temperature of the surrounding air, thus identifying the basic principle of the greenhouse effect.

Foote began testing static electricity, which he called “electrical excitation,” in 1857. The goals of the investigations were to determine the amount of moisture present and what gases in the atmosphere could cause static electricity.

Eunice Foote and her husband Elisha were innovators. In 1860, Eunice applied for a patent in her name for a one-piece vulcanized rubber shoe and boot insole intended to “prevent the squeaking of boots and shoes.” The Emporia News published a story about a strapless skate in 1868. She also invented a new cylindrical-style papermaking machine in 1864.

Awards and honours

Elizabeth’s neighbor Cady Stanton and friend of Eunice Foote took her to attend the 1848 Seneca Falls Convention, the first women’s rights meeting. Foote and her husband Elisha signed the convention’s Declaration of Sentiments as members of the editorial board. Stanton, the author of the document, called for the right to vote, as well as social and legal rights comparable to those enjoyed by men. Along with Stanton, Elizabeth M’Clintock, Mary Ann M’Clintock, and Amy Post, Foote was one of five women who prepared the convention proceedings for publication.

Foote’s work was presented at the American Association for the Advancement of Science (AAAS) in 1856, where his paper titled “Circumstances Affecting the Heat of the Sun’s Rays” was read. However, due to the social and gender prejudices prevalent at the time, his research did not receive widespread recognition. His findings were not published in a scientific journal and, as a result, were not widely disseminated.


Eunice Newton Foote died in 1888 and her important contributions to climate science have gained more recognition in recent years as her story has been rediscovered and recognized. She serves as a reminder of the often overlooked contributions of women scientists throughout history.

Despite the lack of recognition for her contributions, Foote remained dedicated to her scientific pursuits. She was a member of various scientific societies and actively participated in women’s rights movements. Foote’s pioneering experiments on the greenhouse effect laid the foundation for future research in climate science, which has become increasingly important for understanding Earth’s changing weather patterns.
