I'm not entirely certain who "William Travis" is, but it looks like it might be a conflation of two separate people: Sir William Ramsay and Morris Travers, the researchers who discovered krypton. The name krypton comes from a Greek word meaning "hidden." (A week later the same people discovered neon, the name of which comes from a Greek word meaning "new.")
