He won the Gordon Bell Prize for his profound invention of computers, which are used to forecast weather and make predictions about global warming in modern society. Another invention that is seen in everyday life which was made by a Black inventor was the three-light traffic light. Garrett Augustus Morgan initially worked as a sewing-machine repairman but soon became head of multiple companies including a publishing company. He kept up his interest with inventing and, over the years, created a smoke hood and traffic light. His invention was innovated upon and is still used to this day. Behind the invention of the home security system was Marie Van Brittan Brown, a nurse who worked to create and patent a device that served as the template for security systems today. She was challenged by the time it took police officers to arrive at her home and thought up the idea of a home security system. Brown noticed how CCTV cameras were used in hospitals and applied them to the household as a measure of security. She applied for her patent in 1966 which was approved in 1969. After her recognition in the New York Times, her work was awarded by the National Scientists Committee. Brown’s security invention is still used and built upon today in buildings such as apartments, stores, and banks.
