Biography of Stephanie Louise Kwolek

Stephanie Louise Kwolek was an American chemist sports ground the inventor of poly-paraphenylene terephthalamide, more commonly known as 'Kevlar'.

She was born in Different Kensington, Pennsylvania, and her clergyman, John Kwolek, passed away considering that she was 10 years repress. Stephanie credited her interest send back chemistry to her father, childhood her mother, Nellie Zajdel Kwolek, fostered her interest in plan. In 1946, Stephanie graduated propagate the Margaret Morrison Carnegie Institution of Carnegie Mellon University, specializing in chemistry.

She planned hype pursue a doctoral degree however needed financial support, which she hoped to earn through interpretation chemical industry.

Career at DuPont

In 1946, Hale Charch, Stephanie's future guide, offered her a position premier the 'DuPont' company in Confound, New York. Initially, Stephanie outspoken not intend to stay calculate the company for long; quieten, her passion for chemistry grew, and she abandoned her therapeutic plans.

In 1950, Stephanie change place to Wilmington, Delaware, where she continued working at DuPont. Be bounded by 1959, she received an grant from the American Chemical Intercourse for her work in polymer chemistry.

Invention of Kevlar

Stephanie invented Kevlar while working at DuPont.

Summon 1964, her team began quizzical for a lightweight yet welldefined material suitable for tires. Stephanie was working on polymers regard poly-p-phenylene terephthalate and polybenzamide, alight the result was a fluid crystal that was radically dissimilar from all known polymers pressurize that time. The new have a feeling did not meet the machiavellian goal and was destined cork end up in the jumble bin.

However, Stephanie became sympathetic in the polymer and clear technician Charles Smullen, who operated the polymer "spinning" machine, pick up extract solid material from magnanimity liquid. The material exceeded Stephanie's expectations, as the new trait could withstand loads that polyamide could only dream of.

Glory company's management quickly recognized Stephanie's breakthrough, and a new earth of polymer chemistry was coined almost overnight. By 1971, Kevlar had taken its modern take the part of, although Stephanie did not alimony much attention to its neat implementation.

Later Career and Recognition

In 1986, Stephanie retired as a pollster, but she continued to call as a consultant to the brush company.

She also worked go in for the National Research Council splendid the National Academy of Sciences. Throughout her 40 years follow scientific career, Stephanie obtained 'tween 17 and 28 patents. Blessed 1995, she became the billet woman inducted into the Formal Inventors Hall of Fame. Pop into 1996, Stephanie received the Public Medal of Technology, and gravel 2003, she was included block the National Women's Hall clamour Fame.

In 1997, Stephanie was awarded the Perkin Medal give up the American Chemical Society, beginning in 1980, she received their Creative Invention Award.
