  • Alexander Miles was an African-American inventor responsible for improving the method of the opening and closing of elevator doors. He designed a practical method for the closing of the door to the elevator shaft when an elevator was not on a particular floor. Miles created an automatic mechanism that closed access to the shaft. When the elevator would arrive or depart from a given floor, the doors would move automatically. Previously, the opening and closing of the doors of both the shaft and the elevator had to be completed manually by either the elevator operator or by passengers, contributing greatly to the hazards of operating an elevator. People would forget to close the door and, as a result, people could fall down into the elevator shafts. Miles was an African-American inventor who was inducted into the Inventors Hall of Fame. He made major contributions to the development and advancement of elevator technology, making possible their safer use in high-rise buildings and leading indirectly to the creation of the modern city.
