Eunice Newton Foote: The woman who discovered the greenhouse effect

Eunice Newton Foote, who found the greenhouse impact and was a pivotal determine in ladies’s rights actions, is the main focus of at present’s Google doodle.

The discovery of the greenhouse impact is commonly attributed to physicist John Tyndall, who carried out a sequence of experiments in 1859 how warmth affected air. However, in 2011, newbie historian Raymond Sorenson found a report of a presentation of Foote’s work on the tenth annual assembly for the American Association for the Advancement of Science in 1856, two years earlier than Tyndall’s experiments began.

The report, which can also be the primary report of a physics article by a feminine scientist, described Foote’s experiments how tubes of various gases, reminiscent of oxygen, air, hydrogen and carbon dioxide, warmed when uncovered to daylight. She concluded that “The highest effect of the sun’s rays I have found to be in carbonic acid gas”, which is primarily carbon dioxide.

She went on to invest that “an atmosphere of that gas would give to our earth a high temperature”.

The significance of Foote’s findings apparently wasn’t recognised by the scientists current, maybe as a result of her work was truly introduced by the secretary of the Smithsonian Institution, Joseph Henry, who later wrote: “Although the experiments were interesting and valuable, there were [many difficulties] encompassing [any] attempt to interpret their significance.”

Foote was born in 1819 to Theriza Newton and Isaac Newton Jr, the latter of whom was a distant relative of the well-known scientist. Foote was a outstanding activist within the US ladies’s rights motion advocating for, amongst different issues, the common proper to vote. She was one of many unique signatories of a manifesto referred to as the Declaration of Sentiments. This was written on the first women-organised ladies’s rights conference, which befell in 1848 in Seneca Falls, New York.

Though Foote wasn’t vastly lively in scientific analysis for for much longer after her 1856 experiments, she did carry out experiments a few years later which gases may produce static electrical energy. She additionally filed numerous patents, reminiscent of a thermostatically managed cooking range, earlier than she died in 1888.
