Episode Description

Sara Little Turnbull was a force in the world of material science and industrial design. It’s safe to say most people will have used something that started life on her drawing board, but few will know her name. She worked with engineered fabrics at 3M, designing a moldable bra cup that inspired the design of the N95 mask. Later 3M disputed her role in coming up with the mask. She also worked on clear glass cooktop development, the early microwave, storage systems, and many other products.
