George Westinghouse’s best‑known invention is the Westinghouse air brake — an automatic compressed‑air braking system for trains, patented in 1869, that greatly improved railroad safety and control. He later founded the Westinghouse Electric Company and was a major promoter and developer of alternating‑current power distribution (licensing and commercializing Nikola Tesla’s AC patents) and produced many related electrical and railway technologies.
