Physicist John Tyndall is often credited w discovering the greenhouse effect, which he wrote about in 1859.

But Eunice Foote published a paper - 3yrs earlier - demonstrating how atmospheric water vapor & CO2 affected solar heating. She theorized that heat trapping gases in Earth’s atmosphere warm its climate.

Tyndall was widely read. And Foote, being a woman, wasn't even permitted to present her own work. http://www.climate.gov/news-features/features/happy-200th-birthday-eunice-foote-hidden-climate-science-pioneer #history #science #ClimateChange

Born on July 17, 1819, Eunice Newton Foote was an amateur scientist and a women's rights campaigner who was friends with American suffragist Elizabeth Cady Stanton. Foote's experiments with atmospheric gases and her insights about past climate were overlooked for more than a century.
