"First Lieutenant Annie G. Fox was the first woman to receive the Purple Heart in October 1942 for her "singularly meritorious act of extraordinary fidelity or essential service" during the attack on Pearl Harbor in December of 1941, and was later awarded the Bronze Star Medal in October of 1944. Joan Elisabeth Lowther Clarke worked as deputy head of Hut 8 at Bletchley Park alongside Alan Turing during World War II, and was instrumental in the decryption of the German Enigma cipher; she was later appointed a Member of the Order of the British Empire in 1946. Katharine Burr Blodgett invented nonreflective glass while working for General Electric in 1937, two years after which that glass was used in the production of the Academy Award winning film Gone With the Wind. She later invented poison gas adsorbents and methods for deicing aircraft wings, and was inducted into the National Inventors Hall of Fame in 2007. Welsh physicist Joan Elizabeth Curran invented chaff, the method of dumping packets of aluminum strips from aircraft to generate clouds of false radar echoes, in 1942, as well as contributing to the development of the proximity fuse and the electromagnetic isotope separation process. Chemist Stephanie Kwolek discovered the heat-resistant superstrong synthetic fiber poly-paraphenylene terephthalamide, which was later developed into Kevlar KM2 for enhanced ballistic resistance and armored applications, while working at DuPont in 1964."
