An extract from Wikipedia: " Whitcomb L. Judson was an American mechanical engineer from Chicago who was the first to invent, conceive of the idea, and to construct a workable zipper.[2] The method, still in use today, is based on interlocking teeth. Initially it was called the “hookless fastener” and was later redesigned to become
more reliable."
