Patsy Sherman Co-Invented Scotchgard

Patsy Sherman was an American chemist who is known for co-inventing the stain and water repellent Scotchgard. The invention was actually an accident. Sherman was working with her colleagues to develop a rubber that could be used for jet fuel hoses. While working in the laboratory, some of a fluorochemical rubber accidentally got on an assistant’s shoe and it didn’t come off, but it also didn’t change the appearance of the shoe fabric. Sherman then realized that this material could be used as a repellent for oil or water. She worked with Samuel Smith and in 1956 developed the fabric stain repellent and material protector, Scotchgard. The scientists continued their work and expanded the use of their discovery to include a carpet treatment, automotive upholstery cleaner and numerous other derivations.
