George Westinghouse

Verified Timeline

Lore & Background

Westinghouse's interest in railroad switching and natural gas distribution led him to electrical power distribution in the early 1880s. In 1885, he became aware of the Gaulard-Gibbs transformer design, which could step up AC voltage for long-distance transmission and step it down for consumer use. Recognizing AC's potential for economies of scale, he founded the Westinghouse Electric Corporation in 1886. His company directly competed with Thomas Edison's direct current (DC) system. Westinghouse Electric won the contract to illuminate the 'White City' at the 1893 Columbian Exposition in Chicago with AC, and installed the world's first large-scale AC power generation plant at Niagara Falls, New York, which opened in August 1895. Ironically, Westinghouse received the 1911 Edison Medal of the American Institute of Electrical Engineers 'for meritorious achievement in connection with the development of the alternating current system'.

Reader's Guide

George Westinghouse's significance lies in his transformative contributions to transportation and energy. His invention of a train braking system using compressed air, first publicly demonstrated in 1869 in Pittsburgh, revolutionized the railroad industry worldwide. He founded the Westinghouse Air Brake Company in 1869. He and his engineers also developed track-switching and signaling systems, leading to the founding of Union Switch & Signal in 1881. In the early 1880s, he developed inventions for the safe production, transmission, and use of natural gas, sparking a new energy industry. By 1886, his Philadelphia Company owned 58 wells and 184 miles of distribution piping in the Pittsburgh area, serving over 12,000 private homes and 582 industrial customers by 1887. Most notably, his embrace of alternating current for electric power distribution overcame the limitations of direct current, enabling long-distance transmission and large-scale power generation. The success of the AC system at the 1893 Columbian Exposition and the Niagara Falls plant, which opened in August 1895, demonstrated its viability. His legacy includes 360 patents and 61 companies, many still operating.

Did You Know?

• Westinghouse received 360 patents during his career and established 61 companies.
• At age 19, he received his first patent for a rotary steam engine.
• He served in the Union Army and Navy during the Civil War, earning promotion to corporal and serving as an Acting Third Assistant Engineer.
• In 1884, a gas well on his estate blew the top off the derrick, and it took him a week to cap the flow.
• He received the 1911 Edison Medal for his work on the alternating current system.

Common Misconceptions (Editorial)

A common misconception is that George Westinghouse was primarily an electrical engineer focused solely on AC power. In fact, he was a prolific inventor and industrialist who received 360 patents and established 61 companies, with his early work including the railway air brake and innovations in railroad switching and natural gas distribution. Another misconception is that Westinghouse and Thomas Edison were direct peers in age and career timing; however, Westinghouse was born in 1846 (the same year as Edison’s birth) and began his electrical work in the early 1880s, with his company founded in 1886, directly competing with Edison’s DC system.

Why It Matters (Editorial)

George Westinghouse’s legacy endures because his embrace of alternating current made large-scale, long-distance electricity distribution practical, powering the modern world’s infrastructure. His competitive drive against Edison’s DC system, culminating in the illumination of the 1893 Columbian Exposition and the Niagara Falls power plant, fundamentally shaped how electricity is generated and delivered today. Beyond electricity, his 360 patents and 61 companies reflect a model of innovation-driven entrepreneurship that continues to influence industrial development.
