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

Google Doodle: Multinational tech giant Google is celebrating Eunice Newton Foote’s 204th birthday with an awesome slideshow doodle. She is the first scientist to come to the conclusion that certain gases heat up when exposed to sunlight and that increased carbon dioxide (CO2) changes the temperature of the atmosphere and can affect the atmosphere. Queen. This phenomenon is now known as the “greenhouse effect”.

Today #GoogleDoodle honors American scientist and women’s rights activist, Eunice Newton Foote.

Foote was born on July 17, 1819 in Goshen, Connecticut, United States. She is an American scientist, inventor, and women’s rights advocate, raised in a time when women’s opportunities for education and scientific participation were limited, but she still pursued her passion. his science. According to the official Google Doodle website, “At this time, women were shunned by the scientific community. Undeterred, Foote conducted the experiment himself. After placing a mercury thermometer in glass cylinders, she discovered that carbon dioxide cylinders had the most significant heating effect in the sun. Foote is ultimately the first scientist to find a link between elevated levels of carbon dioxide and warming of the atmosphere.”


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

Foote began performing tests of static electricity which she called “electrical excitation” in 1857. The goal of the investigation was to determine how much moisture was present and what gases in the atmosphere could cause static. electricity.

Eunice Foote and her husband Elisha are innovators. In 1860, Eunice applied for a patent bearing her own name for a monolithic vulcanized rubber shoe and boot spacer intended to “stop the creaking of boots and shoes”. The Emporia News ran a story about a skate without straps in 1868. She also invented a completely new cylindrical paper-making machine in 1864.

Awards & Recognition

Elizabeth Cady Stanton’s neighbor and friend of Eunice Foote brought her to the Seneca Falls Convention of 1848, the first gathering for women’s rights. Foote and her husband Elisha were the signatories of the conference’s Declaration of Affection as editorial board members. Stanton, the document’s author, calls for suffrage as well as social and legal rights equivalent to those enjoyed by men. Along with Stanton, Elizabeth M’Clintock, Mary Ann M’Clintock and Amy Post, Foote was one of five women preparing the publishing process for the conference.

Foote’s work was presented at the American Association for the Advancement of Science (AAAS) in 1856, where her paper entitled “Instances Affecting the Heat of the Sun’s Rays” is read. However, due to the social and gender biases prevalent at the time, her research did not receive wide recognition. Her findings were not published in scientific journals and as a result they were not widely available.


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 acknowledged. She serves as a reminder of the often overlooked contributions of female scientists throughout history.

Although her contributions are not recognized, Foote is dedicated to pursuing her scientific goals. She is a member of various scientific associations and actively participates in movements for women’s rights. Foote’s pioneering experiments on the greenhouse effect laid the groundwork for future research in climate science, research that will become increasingly important in understanding Earth’s changing climate patterns. .
