Women In STEAM Fields

Katherine Blurr Blodgett


Physicist, Chemist and Inventor. She was the first woman to be awarded a Ph.D. in physics from the University of Cambridge, in 1926. She was also the first female research scientist at General Electric. She is known for her work on surface chemistry, in particular her invention of "invisible" or nonreflective glass where the non-reflective coating is called a Langmuir–Blodgett film. In addition to developing her famous anti-reflective coating, Blodgett also came up with a method to measure the thickness of very thin films, developed a device that could be used on weather balloons to measure air humidity quickly, and worked to improve gas mask technology. She was issued eight US patents during her career and was the sole inventor on all but two of them. More…
