Black History Month 21 – Garrett Augustus Morgan, Sr. was an African American inventor and community #leader. His most notable #inventions included a type of protective #respiratory hood (or gas mask), a #traffic signal, and a hair-straightening preparation. He is renowned for a heroic rescue in 1916 in which he and three others used his safety hood device to save workers trapped in a #water intake tunnel being dug under Lake Erie after a natural #gas explosion and fire which took the lives of workers and the first police officers and #firefighters who attempted to rescue them. He is also credited as the first #African-American in #Cleveland, Ohio, to own an #automobile.
