The son of freed slaves, Garrett Morgan was determined to have a better life than laboring in the Kentucky fields with his parents and ten siblings. He began by sweeping floors in a clothing factory in Cleveland, Ohio, where he decided to invent a stronger belt for sewing machines. When he was promoted to sewing-machine repairman, Garrett was on his way. In 1911, 146 workers died in the shocking Triangle Shirtwaist Factory fire in New York City, so Garrett decided to invent a safety hood for firefighters. Little did he know that most people wouldn't be interested in buying his safety hood when they discovered its inventor was black. But an explosion that trapped workers in a tunnel under Lake Erie soon changed all that. Garrett's hoods were rushed to the scene and used to rescue as many men as possible. Developed further, Garrett's invention came to save thousands of soldiers from chlorine gas in the trenches of World War I.
