In 1943, Richard James invented one of the greatest toys ever. James, a naval engineer, was conducting an experiment with tension springs. During the experiment, one of the springs fell to the floor and began to "walk." James took the spring home to his wife, Betty, and asked her if she thought it was something they could pursue. Betty had a vision for a toy and scoured the dictionary, looking for an appropriate name. She came across the word "slinky," a Swedish word meaning stealthy, sleek and sinuous. Toy history was made.
