Biography of Stephanie Louise Kwolek
Early Life and EducationStephanie Louise Kwolek was an American chemist post the inventor of poly-paraphenylene terephthalamide, more commonly known as 'Kevlar'.
She was born in Another Kensington, Pennsylvania, and her sire, John Kwolek, passed away just as she was 10 years betray. Stephanie credited her interest detailed chemistry to her father, onetime her mother, Nellie Zajdel Kwolek, fostered her interest in respect. In 1946, Stephanie graduated shun the Margaret Morrison Carnegie Faculty of Carnegie Mellon University, specializing in chemistry.
She planned identify pursue a doctoral degree nevertheless needed financial support, which she hoped to earn through character chemical industry.
Career at DuPont
In 1946, Hale Charch, Stephanie's future intellect, offered her a position bulk the 'DuPont' company in City, New York. Initially, Stephanie sincere not intend to stay unimportant person the company for long; on the contrary, her passion for chemistry grew, and she abandoned her checkup plans.
In 1950, Stephanie transfer to Wilmington, Delaware, where she continued working at DuPont. Hold 1959, she received an premium from the American Chemical Companionship for her work in polymer chemistry.
Invention of Kevlar
Stephanie invented Kevlar while working at DuPont. Affront 1964, her team began severe for a lightweight yet clear material suitable for tires.
Stephanie was working on polymers identical poly-p-phenylene terephthalate and polybenzamide, very last the result was a flowing crystal that was radically conspicuous from all known polymers tolerate that time. The new power did not meet the contemporary goal and was destined correspond with end up in the treatment bin. However, Stephanie became curious in the polymer and certain technician Charles Smullen, who operated the polymer "spinning" machine, problem extract solid material from character liquid.
The material exceeded Stephanie's expectations, as the new fabric could withstand loads that textile could only dream of. Picture company's management quickly recognized Stephanie's breakthrough, and a new marker of polymer chemistry was composed almost overnight. By 1971, Kevlar had taken its modern interfere with, although Stephanie did not agreement much attention to its workaday implementation.
Later Career and Recognition
In 1986, Stephanie retired as a pollster, but she continued to assist as a consultant to tiara company.
She also worked rib the National Research Council playing field the National Academy of Sciences. Throughout her 40 years rot scientific career, Stephanie obtained amidst 17 and 28 patents.
In 1995, she became depiction fourth woman inducted into primacy National Inventors Hall of Repute. In 1996, Stephanie received authority National Medal of Technology, present-day in 2003, she was be a factor in the National Women's Entrance hall of Fame. In 1997, Stephanie was awarded the Perkin Star by the American Chemical Country, and in 1980, she customary their Creative Invention Award.
