Garrett Morgan was an African American inventor, entrepreneur, and community leader who made significant contributions to Black history. He was born in 1877 in Kentucky and is best known for his inventions that revolutionized public safety and transportation.

One of Morgan's most notable inventions was the three-position traffic signal, which he patented in 1923. This traffic signal included the "stop" and "go" signals that we still use today, as well as a warning signal that alerted drivers to prepare to stop. Morgan's invention helped improve road safety and regulate traffic flow in cities across the country.

In addition to his work on the traffic signal, Garrett Morgan also developed the first safety hood or gas mask. He created this device after witnessing a mining disaster in which many workers died from inhaling toxic fumes. Morgan's safety hood was later used by firefighters, soldiers, and workers in various industries to protect them from harmful gases and smoke.

Overall, Garrett Morgan's inventions had a lasting impact on public safety and transportation, and his legacy as an African American inventor continues to inspire future generations.
