Garrett Morgan was an African American inventor known for inventing the three way traffic signal. He was born on March 4, 1877 in Paris, Kentucky. He always enjoyed experimenting with new ideas. One day while driving through Cleveland, he saw a car collide with a horse and carriage. This accident inspired him to invent a signal for managing traffic at intersections. On November 20, 1923, he was awarded a patent for inventing a three way traffic signal. A patent is a right granted to an inventor by the federal government that permits the inventor to exclude others from making, selling or using the invention for a period of time. With his three way traffic signal, traffic could move more orderly without an officer present. Because of his invention, the world is a safer and more orderly place in which to live.
