American inventor Katharine Burr Blodgett is best remembered for her outstanding contributions to the field of optics. While studying surface chemistry, she developed a new method of measuring glass that allowed her to find the thickness of transparent layers to the nearest one-millionth of an inch. This technique led her to invent the first non-reflective glass in 1938. A revolutionary discovery, her invention made eyeglasses, cameras, telescopes, and microscopes all more effective.
During WWIII, Blodgett invented protective smoke screens that saved hundreds of soldiers who would have otherwise been exposed to toxic smoke.
The first female scientist hired by General Electric, Blodgett paved the way for future women in science. She was also the first woman to earn a Ph.D. in physics from Cambridge University, the first woman to be honored with the Photographic Society of America Award, and the first woman to receive the Francis P. Garvin Medal.
