Listen to the podcast to hear the conversation. 

In recognition of Women’s History Month, The Spark spoke with Judith Kaplan, Public Historian of Science, about the life and legacy of Stephanie Kwolek and the broader impact of women in scientific discovery. Kwolek, a Pennsylvania native, was a pioneering chemist whose groundbreaking work in polymer research led to the invention of Kevlar—a material known for its extraordinary strength and used in everything from bulletproof vests to protective gear. Kaplan highlighted how Kwolek’s curiosity and persistence helped redefine possibilities in materials science, while also opening doors for future generations of women in STEM fields. Their conversation underscored not only Kwolek’s lasting influence, but also the vital contributions women continue to make across the scientific community.
