Glass anti-glare (Katherine Blodgett, Schenectady, New York).
a certain age who has always worn glasses and remember what they were certainly scomede and annoying the old lenses that reflect light. But Katharine Burr Blodgett (1898 - 1979) not are grateful just short-sighted, astigmatic, presbyopic, and so on: the anti-glare lenses (1939), the fruit of his genius, was used for microscopes and projectors, cameras and compasses. The distortions of the reflection children, and problems that are earned, are thus a thing of the past thanks to this lady who has a record no small feat: it is the first woman appointed in the research laboratories of General Electric in Schnectady New York, where he worked as assistant to Irving Langmuir, Nobel Laureate in Chemistry. The stimuli did not miss, so much so that later it is also the first woman to earn a place in the PhD in Physics from Cambridge University. When he returned to Schenectady, the student than the teacher, in fact, the inventions of Langmuir, which concern the monomolecular coatings (oil chemical components that cover the surface of the water, metal or glass, forming a film that has exactly the same thickness of a molecule), are of scientific curiosity not have a practical application. Blodgett as he realizes that these films reduce glare on the water surface, may also reduce the glare of reflected light on glass surfaces. After several tests, thanks to a film based on barium, we define the first lens in the world 100% transparent, truly invisible. Receives a patent for the "structure of the film and the method of preparation that gave the world a valuable product. And he has found the most varied applications (take for example the construction of the wings of airplanes resistant to ice).
