Garrett Morgan significantly impacted public safety and health through his inventions, most notably the three-position traffic signal, which improved road safety by helping to regulate vehicle and pedestrian traffic. He also invented a safety hood, an early version of a gas mask, which was used by firefighters and later adopted by the military during World War I. Additionally, Morgan was a prominent advocate for African American rights and worked to improve the lives of his community, leaving a legacy of innovation and social progress.
