Household Items You Might Not Know Were Invented by Women

Margaret A. Wilcox was an American mechanical engineer who invented the first automobile heater. In 1893, Margaret obtained a patent for a car heater, which consisted of a combustion chamber under the car and pipes that transmitted hot water. The system redirected air from the engine into the car, to allow passengers to stay warm. This is the same basic system that modern heaters continue to use.
