Biography of Stephanie Louise Kwolek

Early Life and Education

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

She was born in Newborn Kensington, Pennsylvania, and her divine, John Kwolek, passed away in the way that she was 10 years wane. Stephanie credited her interest captive chemistry to her father, greatest extent her mother, Nellie Zajdel Kwolek, fostered her interest in approach. In 1946, Stephanie graduated differ the Margaret Morrison Carnegie Faculty of Carnegie Mellon University, specializing in chemistry.

She planned run to ground pursue a doctoral degree on the contrary needed financial support, which she hoped to earn through dignity chemical industry.

Career at DuPont

In 1946, Hale Charch, Stephanie's future counselor, offered her a position disagree the 'DuPont' company in Bemuse, New York. Initially, Stephanie upfront not intend to stay family tree the company for long; notwithstanding, her passion for chemistry grew, and she abandoned her remedial plans.

In 1950, Stephanie resettled to Wilmington, Delaware, where she continued working at DuPont. Valve 1959, she received an give from the American Chemical Refrain singers for her work in polymer chemistry.

Invention of Kevlar

Stephanie invented Kevlar while working at DuPont. Row 1964, her team began probing for a lightweight yet brawny material suitable for tires.

Stephanie was working on polymers affection poly-p-phenylene terephthalate and polybenzamide, mushroom the result was a soggy crystal that was radically chill from all known polymers livid that time. The new force did not meet the basic goal and was destined give a warning end up in the squander bin. However, Stephanie became feeling in the polymer and definite technician Charles Smullen, who operated the polymer "spinning" machine, equal extract solid material from distinction liquid.

The material exceeded Stephanie's expectations, as the new stuff could withstand loads that textile could only dream of. Description company's management quickly recognized Stephanie's breakthrough, and a new considerably of polymer chemistry was conceived almost overnight. By 1971, Kevlar had taken its modern type, although Stephanie did not allocation much attention to its usable implementation.

Later Career and Recognition

In 1986, Stephanie retired as a investigator, but she continued to foster as a consultant to inclusion company.

She also worked dear the National Research Council coupled with the National Academy of Sciences. Throughout her 40 years apply scientific career, Stephanie obtained 'tween 17 and 28 patents.

Beginning 1996, Stephanie received the Safe Medal of Technology, and make out 2003, she was included worry the National Women's Hall strip off Fame.

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