George Westinghouse Biography: From Rail Brakes to Electric Power

In 1893, electric lights powered by Westinghouse Electric illuminated the World’s Columbian Exposition in Chicago. It was a highly visible success for alternating-current power at a time when different approaches to electricity distribution were competing for commercial acceptance.

George Westinghouse had not begun his career in electricity. His earlier breakthrough was a compressed-air railway brake that allowed a locomotive engineer to control braking across a train. From rail equipment to electrical generation, he repeatedly helped turn technical developments into systems that businesses could manufacture and use.

The scale of those achievements did not protect him from financial reversals. After the panic of 1907, important companies associated with his name entered receivership, and he eventually lost control of enterprises he had helped establish.

A Quick Look at the Life of George Westinghouse

Mechanical Work Before the Railways

Westinghouse grew up around practical mechanical work. His father, George Westinghouse Sr., operated an agricultural-machinery shop in Schenectady, New York. His mother was Emeline Vedder.

During the Civil War, the younger Westinghouse served in the Union military, including cavalry service and later an engineering assignment aboard the Union Navy vessel USS Muscoota. After the war he briefly attended Union College, though he did not graduate.

In 1865, he obtained his first patent, for a rotary steam engine. He also worked on equipment intended to return derailed railway cars to their tracks. These mechanical inventions preceded the railroad system that would establish his industrial career.

Westinghouse married Marguerite Erskine Walker in 1867. Their son, George Westinghouse III, was born in 1883.

The Air Brake Becomes a Railway Business

Railway braking presented a fundamental coordination problem. Brakemen often had to apply brakes separately to individual cars following signals from a locomotive engineer. A train’s braking therefore relied on people distributed across its length.

Westinghouse developed a system that used compressed air to place braking control with the locomotive engineer. In 1869, he received an air-brake patent and established the Westinghouse Air Brake Company. The invention was not simply a mechanical device to patent: the company provided a means to manufacture and introduce the system into railway service.

The work continued after the initial patent. In 1872, Westinghouse introduced an automatic air brake, an important further development rather than another name for the original 1869 design.

His railway interests broadened into other operating systems. In 1882, he organized the Union Switch and Signal Company. The federal Safety Appliance Act of 1893 subsequently advanced requirements involving railroad braking equipment, although compliance did not become universal at once.

The brake business also developed workplace programs. The Westinghouse Air Brake Company adopted a nine-hour day and a 55-hour workweek in 1869, followed by a Saturday half-holiday in 1871. In Wilmerding, Pennsylvania, company housing and employee programs formed part of its industrial operations. Those benefits existed within a company-town environment in which workers could also be strongly dependent on their employer.

From Rail Systems to Gas and Electric Power

Westinghouse’s business activities extended beyond railroads. During the 1880s, he worked on apparatus for more controlled natural-gas transmission and use, including piping and associated equipment.

Electric power presented a different set of problems. As electrical service expanded, distributing electricity over useful distances became commercially important. Alternating-current systems could use transformers to increase voltage for transmission and then reduce it for local use, giving them an advantage over contemporary low-voltage direct-current distribution.

Westinghouse pursued relevant patent rights and financed technical development. The Westinghouse Electric Company was organized in 1886, bringing him into an emerging industry where commercial results required contributions from engineers, manufacturers and power suppliers.

William Stanley Helps Make AC Practical

William Stanley Jr. was central to the electrical company’s early technical progress. With Westinghouse’s financial support, Stanley developed an improved transformer and demonstrated practical alternating-current lighting in Great Barrington, Massachusetts, in March 1886.

By November 1886, a Westinghouse enterprise also had a commercial AC installation in Buffalo, New York. The company’s advances drew on rights associated with Gaulard and Gibbs, Stanley’s improvements and further work by Westinghouse engineers.

Stanley’s work and the Buffalo installation gave the young company working examples of AC distribution. Westinghouse supplied financial and organizational support; the technical advances came from several engineers and inventors.

Tesla’s Patents and the Competition Over Electricity

In 1888, Westinghouse acquired rights to Nikola Tesla’s polyphase alternating-current patents, including motor-related technology, and engaged Tesla in related development. The rights expanded the technical possibilities available to the enterprise, while Tesla retained credit for his own contributions.

The AC business faced competition from Edison-associated direct-current interests. Public arguments about electrical safety accompanied commercial and patent disputes in what later became known as the “War of the Currents.” Advocates associated with Edison criticized AC safety; the rivalry was broader than a personal contest between two inventors.

Commercial demonstrations and technical advances mattered alongside the competition. The contest did not end with a single decisive event.

Chicago Makes Alternating Current Visible

The 1893 World’s Columbian Exposition gave Westinghouse Electric a major public opportunity. The company won the contract for much of the exposition’s electric lighting and delivered a conspicuous large-scale display of AC in use.

The exposition increased the visibility and acceptance of alternating current. Its success belonged to the company’s engineers and other personnel as well as to Westinghouse’s leadership. It did not settle every patent dispute, eliminate safety concerns or instantly displace all direct-current systems.

At Niagara Falls, AC would be tested on the scale of a major power system.

Niagara Falls: Generation First, Transmission Later

The Niagara Falls power development was a large undertaking involving the Niagara Falls Power Company, Edward Dean Adams, engineers, financiers and multiple industrial suppliers. Westinghouse Electric designed and manufactured major generators for the project; George Westinghouse did not own or single-handedly create the whole development.

One surviving machine illustrates the project’s scale. Generator No. 1 at the Adams Station, built by Westinghouse Electric & Manufacturing Company, was rated at 5,000 horsepower and supplied two-phase alternating current. It began operating on August 26, 1895.

Niagara began generating power in 1895, but transmission to Buffalo followed in November 1896. The distinct milestones showed how large generating equipment and long-distance transmission could operate as parts of a wider power system.

Industrial Expansion and a Financial Reversal

By the turn of the twentieth century, the businesses associated with Westinghouse formed a substantial industrial group. Retrospective accounts estimate that the enterprises collectively employed about 50,000 people. Across his career he was associated with dozens of companies and hundreds of patents, although precise retrospective counts differ by definition.

The scale of the operations can be seen in films made at Westinghouse facilities in 1904. The American Mutoscope and Biograph Company, with cameraman G. W. Bitzer, recorded factory work and employees for films exhibited at the St. Louis World’s Fair. The films offer a glimpse of manufacturing activity, though they were also promotional presentations.

The financial panic of 1907 marked a major reversal. Important Westinghouse enterprises experienced serious distress and receivership. Reorganization eroded Westinghouse’s corporate control, and by 1911 he had become separated from the companies he had helped build.

The air-brake enterprise continued, even as Westinghouse lost control of important businesses. His financial reversal was not the result of a simple personal defeat by an electrical rival.

Recognition, Final Years and Legacy

In 1911, Westinghouse received the Edison Medal for his contributions to alternating-current lighting and power. The honor came after his loss of corporate control, but it did not establish that he and Thomas Edison had personally reconciled.

George Westinghouse died in New York City on March 12, 1914, at age 67. He was buried at Arlington National Cemetery, reflecting his military service during the Civil War.

Westinghouse’s influence extended from the control of moving trains to the distribution of electric power. In both fields, he helped carry inventions into commercial operation through companies and engineering partnerships. His legacy rests as much on that work of organization and collaboration as on his own patents.
