As per our current Database, Stephanie Kwolek died on Jun 18, 2014 (age 90).
She studied chemistry at Margaret Morrison Carnegie College, where she graduated in 1946.
Kwolek was born to Polish immigrant parents in the Pittsburgh suburb of New Kensington, Pennsylvania, in 1923. Her father, John Kwolek (Polish: Jan Chwałek), died when she was ten years old. He was a naturalist by avocation, and Kwolek spent hours with him, as a child, exploring the natural world. She attributed her interest in science to him and an interest in fashion design to her mother, Nellie (Zajdel) Kwolek, who worked as a seamstress.
In 1946, Stephanie earned a Bachelor of Science degree with a major in chemistry from Margaret Morrison Carnegie College of Carnegie Mellon University. She had planned to become a doctor and hoped she could earn enough money from a temporary job in a chemistry-related field to attend medical school.
William Hale Charch, a future mentor, offered Kwolek a position at DuPont's Buffalo, New York, facility in 1946. This vacancy was due to men being in the military overseas.
Kwolek only intended to work for DuPont temporarily, to raise money to study. When she found the work interesting, she decided to stay and moved to Wilmington, Delaware, in 1950 with DuPont. In 1959, she won a publication award from the American Chemical Society (ACS), the first of many awards. The paper, The Nylon Rope Trick, demonstrated a way of producing nylon in a beaker at room temperature. It is still a common classroom experiment, and the process was extended to high molecular weight polyamides. In 1985, Kwolek and coworkers patented a method for preparing PBO and PBT polymers.
While working for DuPont, Kwolek invented Kevlar. In 1964, in anticipation of a gasoline shortage, her group began searching for a lightweight yet strong fiber to replace the steel used in tires. The polymers she had been working with at the time, poly-p-phenylene terephthalate and polybenzamide, formed liquid crystal while in solution that at the time had to be melt-spun at over 200 °C (392 °F), which produced weaker and less stiff fibers. A unique technique in her new projects and the melt-condensation polymerization process was to reduce those temperatures to between 0 and 40 °C (32 and 104 °F).
In 1980, Kwolek received the Chemical Pioneer Award from the American Institute of Chemists, and an Award for Creative Invention from the American Chemical Society. In 1995, Kwolek was added to the National Inventors Hall of Fame. In 1996, she received the National Medal of Technology and the IRI Achievement Award. In 1997, she received the Perkin Medal from the American Chemical Society. In 2003, she was inducted into the National Women's Hall of Fame.
In 1986, Kwolek retired as a research associate for DuPont. Toward the end of her life, she consulted for DuPont, and served on both the National Research Council and the National Academy of Sciences. During her 40 years as a research scientist, she filed and received either 17 or 28 patents.
For her discovery of Kevlar, Kwolek was awarded the DuPont company's Lavoisier Medal for outstanding technical achievement in 1995, as a "Persistent experimentalist and role model whose discovery of liquid crystalline polyamides led to Kevlar aramid fibers." At the time of her death in 2014, she was still the only female employee to receive that honor. Her discovery generated several billion dollars of revenue for DuPont, being her employer at the time, but she never benefited directly from it financially.
Stephanie's parents were named Nellie and John.
Currently, Stephanie Kwolek is 97 years, 10 months and 13 days old. Stephanie Kwolek will celebrate 98th birthday on a Saturday 31st of July 2021. Below we countdown to Stephanie Kwolek upcoming birthday.
