In 1938, physicist Katharine Burr Blodgett achieved a breakthrough that changed how light moves through glass. Working at General Electric, she created the first non-reflective “invisible” glass, dramatically improving the performance of eyeglasses, camera lenses, and optical instruments. The invention marked a turning point in the science of optics. Blodgett’s technique relied on the precise application of forty-four monomolecular layers to a glass surface, building on earlier research by her c
