In Cleveland OH around the same time men working in mines under Lake Erie were in danger of dying in mines where toxic gases were present. Garrett Morgan volunteered to rescue them because he had recently invented the gas mask. He and his brother brought at least 2 men out alive. Current gas masks are still based on his original design. Later he invented the traffic light after witnessing a fatal accident that killed a young girl. He sold his idea to General Electric for $40,000.
