Eunice Newton Foote showed that carbon dioxide traps the heat of the sun in 1856, beating the so-called father of the greenhouse effect by at least three years. Why was she forgotten?

In 1856, decades before the term “greenhouse gas” was coined, Eunice Newton Foote demonstrated the greenhouse effect in her home laboratory. She placed a glass cylinder full of carbon dioxide in sunlight and found that it heated up much more than a cylinder of ordinary air. Her conclusion: more carbon dioxide in the atmosphere results in a warmer planet.
