About Harry E. Soref

Locksmith, inventor of the laminated steel padlock, and founder of Master Lock Company (1921). As a locksmith, Soref had realized that the cheaper padlocks, made with stamped metal sheels, were poor security because they were easily damaged. He patented (1924) his invention of a laminated padlock which, like bank vault doors and battleships, was built in laminations of layer on layer of steel for greater strength. Unable to sell his invention to a padlock manufacturer, he began making them himself. Master Lock opened its first tiny factory in Milwaukee, Wisc. In 1928 Master Lock gained national recognition for shipping 147,600 padlocks to federal prohibition agents in New York for locking up the speakeasies they raided.
