Eunice Newton Foote

Eunice Newton Foote showed in 1856, using glass cylinders in sunlight, that air containing carbon dioxide heats up more than ordinary air, and suggested this could affect the planet's temperature. Her paper was read at a scientific meeting by Joseph Henry, not by her. John Tyndall's more detailed 1859 work became the standard reference, and her priority was largely rediscovered only in 2011.
