Katherine Burr Blodgett (1898-1979)
Katharine Burr Blodgett 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. Once introduced, nonreflective lenses were used for projectors and cameras by the post-war movie industry. Blodgett’s glass was also used for submarine periscopes and airplane spy cameras during World War II.
