Garrett Morgan was an African American inventor and entrepreneur best known for creating the three-position traffic signal and a safety hood, an early version of the gas mask, which he used to save lives during a tunnel explosion in 1916. Born in 1877 in Kentucky, he moved to Cleveland, Ohio, where he started a tailoring business and later founded a successful hair care company. Morgan also played a significant role in advocating for the rights of African Americans and was involved in the NAACP. His inventions greatly influenced public safety and traffic management, making him a notable figure in American history.
