In ancient Pompeii, engineers used bronze water valves welded into lead piping to regulate flow through the city’s supply system. These plug-style valves, controlled by a rotating insert, functioned much like modern hardware-store models, and were manufactured with consistent standards.

In 1949, the “Man-from-Mars Radio Hat” hit stores across the United States. Developed by Victor Hoeflich of the American Merri-Lei Corporation, it placed a fully functional AM radio into a pith helmet.
