In 1943, mechanical engineer Richard James was working in a Philadelphia shipyard, attempting to develop springs that could support and stabilize sensitive marine instruments. During his experiments, he accidentally knocked a tension spring off a shelf. Instead of simply falling to the ground, the spring stepped down from a stack of books, onto a table, and coiled itself upright on the floor. James spent the next two years determining the perfect steel wire tension to turn this accidental movement into a children's toy, which his wife, Betty, named the "Slinky." [1]
