Dr. Warrick worked for 33 years at Dow Corning and developed 44 patents in his career. In 1990, he published a book titled Forty Years of Firsts: The Recollections of a Dow Corning Pioneer. He is most known as one of the inventors of Silly Putty.
During World War II, Warrick was working on a substitute for rubber, a valuable wartime commodity. According to the story as told by the Dow Corning Corporation, one interesting substance he discovered was considered a mistake; it was too pliable to be a substitute for rubber. The compound was a result of combining a silicone derivative with boric oxide. Despite being a poor substitute for rubber, it had other, unusual properties. Warrick would call this new product ‘bouncing putty,’ far before it became popular as a novelty and later as a children’s toy.
