Who was Mária Telkes?
Mária Telkes (1900–1995) was a Hungarian-born American physical chemist and biophysicist celebrated for her solar energy inventions. After immigrating to the United States, she worked as a biophysicist at the Cleveland Clinic Foundation and later at Westinghouse Electric.
During World War II, Telkes invented a solar distiller to vaporize seawater into drinkable water, which was used on life rafts and to supplement water demands in the Virgin Islands. After the war, she continued her solar energy research at MIT, where she became an associate research professor in metallurgy in 1945.
Telkes designed the world’s first modern solar-heated residence with architect Eleanor Raymond in 1948. She also improved heat-exchanger technology to create solar stoves and heaters and assisted the U.S. Department of Energy in developing the world’s first solar-electric residence in 1980.

What is a physical chemist and a biophysicist?
A physical chemist studies the quantitative aspects of chemical processes to measure, correlate, and explain interactions and transformations of materials. They discover and investigate chemical regularities, often called laws of nature. Subdisciplines include chemical thermodynamics, kinetics, electrochemistry, photochemistry, surface chemistry, and catalysis.
Biophysics emerged from earlier scientific explorations into bioluminescence, animal electricity, diffusion gradients, and osmotic pressure. Biophysicists use the principles of physics to study biological phenomena, separating biological problems into segments that are amenable to physical interpretation and testing hypotheses with experiments.

How did Mária Telkes contribute to solar energy research?
Mária Telkes, a Hungarian-American physical chemist and biophysicist, significantly contributed to solar energy research through her inventions. During World War II, she invented a solar distiller that converted seawater into potable water, which was later scaled up for use in the Virgin Islands.
After the war, Telkes continued her solar energy research at MIT. In 1948, she collaborated with architect Eleanor Raymond to design and construct the world's first solar-heated residence in Dover, Massachusetts, using solar collectors and Glauber's salts for heat storage. Later, with a grant from the Ford Foundation, she developed a solar oven adaptable for various latitudes. Telkes also contributed to the development of materials that could withstand extreme space temperatures and assisted in creating the world's first solar-electric residence in 1980.

What inventions is Mária Telkes especially known for?
Mária Telkes, a Hungarian-American physical chemist and biophysicist, is best known for her inventions related to solar energy. These include the solar distiller, which could vaporize seawater and recondense it into potable water, and the first solar-powered heating system designed for residential use.
During World War II, Telkes invented the solar distiller for the U.S. Office of Scientific Research and Development. In 1948, she designed the first house to use solar energy, which was built in Dover, Massachusetts. The house used solar collectors and Glauber's salts for heat storage. She also improved heat-exchanger technology to create solar stoves and heaters and helped in the development of the world's first solar-electric residence in 1980.

How have Mária Telkes’s contributions impacted science and our daily lives?
Mária Telkes (1900–1995) was a Hungarian-American physical chemist and biophysicist celebrated for her work in solar energy technologies. During World War II, Telkes invented a solar distiller that converted seawater into drinking water, a critical device used on life rafts and later to supplement water supplies in the Virgin Islands.
After the war, Telkes designed the first solar-powered heating system for residences. Built in Dover, Massachusetts, in 1948, the house used solar collectors and Glauber's salts for heat storage. She also created solar stoves and heaters and helped the U.S. Department of Energy develop the world's first solar-electric residence in 1980. Her inventions have had a lasting impact, particularly for those in water-scarce areas, and have paved the way for further advances in solar energy applications.

Mária Telkes (born December 12, 1900, Budapest, Austria-Hungary [now in Hungary]—died December 2, 1995, Budapest) was a Hungarian-born American physical chemist and biophysicist best known for her invention of the solar distiller and the first solar-powered heating system designed for residences. She also invented other devices capable of storing energy captured from sunlight.
Telkes, daughter of Aladar Telkes and Maria Laban de Telkes, was raised in Budapest. She studied physical chemistry at the University of Budapest, graduating with a B.A. in 1920 and a Ph.D. in 1924. She became an instructor at the institution in 1924 but decided to immigrate to the United States after visiting a relative, who served at the time as the Hungarian consul in Cleveland. In 1925 she accepted a position as a biophysicist for the Cleveland Clinic Foundation, where she worked with American surgeon George Washington Crile to create a photoelectric device that recorded brain waves.
Telkes became an American citizen in 1937. That same year she became a research engineer at Westinghouse Electric, where she developed instruments that converted heat into electrical energy; however, she made her first forays into solar energy research in 1939. That year, as part of the Solar Energy Conversion Project at the Massachusetts Institute of Technology (MIT), she worked on thermoelectric devices powered by sunlight. Telkes was assigned to the U.S. Office of Scientific Research and Development during World War II, and it was there that she created one of her most important inventions: a solar distiller capable of vaporizing seawater and recondensing it into drinkable water. Although the system was carried aboard life rafts during the war, it was also scaled up to supplement the water demands of the Virgin Islands. She remained at MIT after the war, becoming an associate research professor in metallurgy in 1945.
Until the end of her career, Telkes continued to develop solar-energy applications and received several patents for her work. Together with American architect Eleanor Raymond, she designed and constructed the world’s first modern residence heated with solar energy. The house was built in Dover, Massachusetts, in 1948. Boxlike solar collectors captured sunlight and warmed the air in a compartment between a double layer of glass and a black sheet of metal. Warmed air was then piped into the walls, where it transferred heat to Glauber’s salts (crystallized sodium sulfate) for storage and later use. She improved upon existing heat-exchanger technology to create solar stoves and solar heaters, receiving a $45,000 grant from the Ford Foundation in 1953 to create a universal solar oven that could be adapted for use by people living at all latitudes. She also worked to develop materials capable of enduring the temperature extremes of space. In 1980 she assisted the U.S. Department of Energy in the development of the world’s first solar-electric residence, which was built in Carlisle, Massachusetts.
In 1952 Telkes became the first recipient of the Society of Women Engineers Achievement Award. In 1977 she received a lifetime achievement award from the National Academy of Sciences Building Research Advisory Board for her contributions to solar-heated building technology and the Charles Greeley Abbot Award from the American Solar Energy Society.
