George Westinghouse

George Westinghouse was a pioneering American engineer and inventor in the late 19th and early 20th centuries. He is best known for his role in developing the alternating current (AC) electrical system, which allowed electricity to be transmitted efficiently over long distances. Westinghouse founded a major electrical company that competed with Thomas Edison’s direct current (DC) system, ultimately facilitating the widespread use of AC power. He also invented the air brake system for trains, significantly improving railway safety. His innovations transformed the energy industry and laid the groundwork for modern electrical infrastructure.
