African-American inventor Garrett Morgan (1877-1963), who is known as the first black citizen to own an automobile in Cleveland, created a respiratory protective hood, a prototype for the modern-day gas mask. He also invented a specific type of traffic signal, as well as a new hair-straightening technique. (Photo: Topical Press Agency, Hulton Archive/Getty Images)
