In 1923, Morgan patented his best-known invention, the three-way traffic signal, based on signs that signaled stop and go. He sold his patent rights to General Electric, which developed an electrical version. Died: 1963Information Please® Database, © 2007 Pearson Education, Inc. All rights reserved.
