@blackexcellist: Alexander Miles was an African American inventor best known for revolutionizing elevator safety with his 1887 patent for automatic elevator doors. Prior to his invention, passengers had to manually open and close both the elevator and shaft doors, posing serious safety risks. Miles’s design used a system of levers and flexible belts to automatically open and close the doors, significantly reducing accidents and paving the way for modern elevators. His innovation not only improved safety but also enhanced the efficiency of vertical transportation in buildings. Miles is remembered as a pioneering figure in engineering and African American innovation.
