Mária Telkes (1900–1995)

Born 1900 CE, died 1995 CE.

Mária Telkes (December 12, 1900 – December 2, 1995) was a Hungarian-American biophysicist, engineer, and inventor who worked on solar energy technologies. She moved to the United States in 1925 to work as a biophysicist. She became an American citizen in 1937 and started work at the Massachusetts Institute of Technology (MIT) to create practical uses of solar energy in 1939. During World War II, she developed a solar water distillation device, deployed at the end of the war, which saved the lives of downed airmen and torpedoed sailors. Her goal was to create a version for villagers in poor and arid regions. Telkes, often called by colleagues The Sun Queen, is considered one of the founders of solar thermal storage systems. After the war, she became an associate research professor at MIT. In the 1940s she and architect Eleanor Raymond created one of the first solar-heated houses, Dover Sun House, by storing energy each day. In 1953 they created a solar oven for people at various latitudes that could be used by children. In 1952, Telkes became the first recipient of the Society of Women Engineers Achievement Award.
