3000 Forint Mária Telkes

Mária Teleki was a Hungarian-American biophysicist whose solar energy research at MIT and later at NYU produced the first solar-heated house in the United States in 1948, built in Dover, Massachusetts. The Hungarian National Bank has issued commemorative coins honoring Hungarian-born scientists with some regularity, and Telkes — who held over twenty patents related to solar energy storage — fits squarely into that tradition. She died in Budapest in 1995, having returned to Hungary late in life.
