The Lock Wizard of Thuringia

Published by Sharni on


Walter Schlage was given this strange name for his magic-like lock skills. The German-born inventor developed a door lock that turned lights on and off in 1909, which was about a century before this technology was widely available in the consumer market. Schlage started his own company, the popular lock manufacturer, in 1920 with a starting capital of $30. It is now one of the most widely recognized security device companies in the world.
