George Westinghouse moved from railroads into electrical power in the 1880s and founded the Westinghouse Electric Company in 1886 to commercialize alternating-current (AC) systems. Rather than being primarily an inventor of every gadget, he was an engineer–entrepreneur who organized manufacturing, financing, and system design so that AC power could be built at industrial scale. His company became one of the first to supply complete power plants and distribution equipment, not just individual machines.
A defining contribution was championing polyphase alternating current for generation and long-distance transmission. Westinghouse licensed Nikola Tesla’s patents for polyphase AC motors and related technology and invested heavily to develop practical AC generators, transformers, and distribution equipment. By backing AC against Thomas Edison’s direct current systems, Westinghouse helped settle the “war of currents” in favor of the technology that proved superior for economical transmission over distance.
Westinghouse also drove the engineering and manufacture of the components that made AC systems practical: step-up and step-down transformers, reliable alternators (AC generators), switchgear, and protection devices. His firm standardized equipment and system architectures, lowered manufacturing costs through mass production, and introduced business models that sold integrated electrical systems—making utility-scale power delivery economically feasible for cities and industry.
One of Westinghouse’s most important practical achievements was winning and executing the Niagara Falls hydroelectric project in the mid-1890s. Westinghouse equipment and polyphase systems were chosen to harness Niagara’s power and transmit it to Buffalo, providing a dramatic, public demonstration that large-scale AC generation and long-distance transmission could work reliably. That success catalyzed rapid adoption of AC grids across the United States and abroad.
Westinghouse’s legacy is therefore less about a single invention and more about converting AC from laboratory idea to nationwide infrastructure. By funding, manufacturing, standardizing, and installing complete AC power systems, he helped make electric lighting, motors, and later the modern electric grid practical and affordable—fundamentally shaping 20th‑century power generation and distribution.
