Which inventor helped create safer gas masks and traffic signaling devices in the early 20th century?

The idea being tested is about an inventor who focused on public safety devices in the early 1900s. Garrett Morgan stands out because he developed the Morgan Safety Hood, a more effective gas mask that miners and rescue workers could use in smoke and chemical environments. He also created a three-position traffic signal, which added a safer, clearer way for drivers and pedestrians to move through intersections by introducing a caution phase. These two innovations show a clear thread of improving safety in both dangerous workplaces and urban streets during that era.

Other famous inventors from that period—Nikola Tesla, Thomas Edison, and Alexander Graham Bell—made extraordinary contributions in electricity, invention, and communication, but their landmark work did not center on safer gas masks or traffic signaling devices.
