Katharine Burr Blodgett was an American scientific researcher. She was the first woman to be awarded a Ph.D. in physics from the University of Cambridge, in 1926. After receiving her master’s degree, she was hired by General Electric, where she invented low-reflectance “invisible” glass.
1907 – Gordon Kidd Teal, American engineer and inventor, is born.
Gordon Kidd Teal was an American engineer. He invented a method of applying the Czochralski method to produce extremely pure germanium single crystals used in making greatly improved transistors. He, together with Morgan Sparks invented a modification of the process that produced the configuration necessary for the fabrication of bipolar junction transistors. He is most remembered for developing the first silicon transistor while at Texas Instruments.
1927 – Fritz Lang’s futuristic film Metropolis is released in Germany.
Metropolis is a 1927 German expressionist epic science-fiction drama film directed by Fritz Lang. He and his wife, Thea von Harbou, wrote the silent film, which starred Gustav Fröhlich, Brigitte Helm, Alfred Abel and Rudolf Klein-Rogge.
