Passage: Hazel Bishop, 92

Hazel Bishop, the inventor of kissproof lipstick, died over the weekend at the age of 92. A trained chemist who later went on to become a stockbroker, financial analyst, and college professor, Bishop developed her winning formula while working in a dermatology lab soon after World War II. She may not have made it into the pantheon of household names, but women -- and men -- the world over have thanked her silently for the lipstick that leaves no trace.
