Garrett Augustus Morgan, Sr. was an African American inventor who originated a respiratory protective hood (similar to the modern gas masks), credited with having a patent for a type of traffic signal. He is renowned for a heroic rescue in which he used his hood to save workers trapped in a tunnel system filled with fumes. He is credited as the first African-American in Cleveland to own an automobile.
How do his inventions tie into the class concepts of simple and compound machines?
