Season 3, Episode 12: Who Invented? The Surprisingly Explosive History of the Traffic Light

We see them every day, but have you ever wondered who actually invented the traffic light? In the debut episode of the new "Who Invented?" series, your host Neo Gentrics tackles the surprisingly complex, innovative, and even explosive history of this everyday device. This is the true story of the multiple inventors who tamed our chaotic streets.

This episode is a journey from the horse-and-buggy traffic jams of 1860s London to the smart, connected intersections of tomorrow. Neo Gentrics breaks down the key innovations and gives credit to the often-overlooked pioneers who made modern traffic flow possible.

This is a complete history of the traffic light, including:

  • The First Attempt: John Peake Knight's gas-powered signal from 1868 and why it was abandoned after it exploded.
  • The Electric Revolution: The early electric signals developed by Lester Farnsworth Wire and James Hoge.
  • The Third Light: How Detroit police officer William Potts added the crucial yellow "caution" light.
  • The Unsung Hero: A deep dive into Garrett Morgan, the Black inventor who patented the first electric three-position signal and sold the rights to General Electric.
  • The Future: A look at smart traffic lights that communicate directly with cars.
