Chemist Stephanie Kwolek was born #OTD in 1923. She invented Kevlar, used in high-strength / low-weight applications like body armor and airplane parts. She also invented the Nylon Rope Trick demo! 🧪 👩‍🔬 Images: DuPont/Stephanie Kwolek

Black and white photo of Stephanie Kwolek standing in front of a microscope. She wears a dark jacket and striped blouse, with a lapel pin that looks like an umbrella. Her dark hair is worn in a short bob and she is looking at the camera. Color photo of Stephanie Kwolek. She wears a blouse with a batik patter. Her hair is still in a short bob but is more gray than the previous photo. Kwolek wears large, yellow rubber gloves and is holding a large pipette full of milky white fluid up to the camera.

Cellular biologist Marilyn Farquhar discovered critical structural components of cells, including tight junctions & desmosomes. A pioneer in electron microscopy, she served as the first female president of the American Society for Cell Biology, 1981-82. She was born #OTD in 1928. #WomenInSTEM

A black-and-white photograph of cellular biologist and pathologist Dr. Marilyn Gist Farquhar (July 11, 1928 – January 16, 2019) at work in a laboratory setting. Seated at a desk, she rests her chin thoughtfully on her left fist while her right hand holds a pen over an open three-ring binder notebook. She wears a crisp white laboratory coat over a dark-and-white patterned, checkered shirt with matching cuffs. Her expression is warm, serene, and intellectually engaged, looking directly toward the camera with a gentle smile. Her short, dark hair is softly styled back. To her right sits a large, vintage electron microscope with its textured metallic columns, representing the primary tool of her monumental discoveries regarding cellular tight junctions, the Golgi apparatus, and renal pathology. The high-contrast composition frames her closely, creating an intimate, focused, and historically significant mood that celebrates her legacy as the first female president of the American Society for Cell Biology.
