Profile
(born Oct. 6, 1846, Central Bridge, N.Y., U.S.—died March 12, 1914, New York City) American inventor and industrialist who was chiefly responsible for the adoption of alternating current for electric power transmission in the United States.After serving in both the U.S. Army and the navy in the Civil War, Westinghouse received his first patent in late 1865 for a rotary steam engine. Though the engine proved impractical, he later applied the same principle to develop a water meter. In that same year he invented a device for placing derailed freight cars back on their tracks.
Westinghouse's interest in railroads in general led to his first major invention, an air brake, which he patented in 1869 (eventually he received more than 100 patents); in the same year he organized the Westinghouse Air Brake Company. With additional automatic features incorporated into its design, the air brake became widely accepted, and the Railroad Safety Appliance Act of 1893 made air brakes compulsory on all American trains. As the use of his automatic air brake spread to Europe, Westinghouse saw the advantages of standardizing all air-brake equipment so that the apparatus on cars of different lines would work together and improved designs could be used on earlier models. He thus became one of the first to adopt the modern practice of standardization.
Westinghouse then turned his attention to the problems of railroad signaling. By purchasing patents to combine with his own inventions, he was able to develop a complete electrical and compressed-air signal system. In 1883 he began to apply his special knowledge of air brakes to the problem of safely piping natural gas, and within two years he obtained 38 patents for piping equipment.
Although the electrical system being developed in the United States in the 1880s used direct current (DC), in Europe several alternating-current (AC) systems were being developed. One of the most successful, first demonstrated in 1881 in London, was devised by Lucien Gaulard of France and John Gibbs of England. Four years later, Westinghouse imported a set of Gaulard-Gibbs transformers and a Siemens AC generator and set up an electrical system in Pittsburgh. With the aid of three American electrical engineers, he altered and perfected the transformer and developed a constant-voltage AC generator. In 1886 he incorporated the Westinghouse Electric Company, which three years later was renamed the Westinghouse Electric & Manufacturing Company. He purchased the patents of Nikola Tesla's AC motor and hired Tesla to improve and modify the motor for use in his power system. When the system was ready for the American market, the advocates of DC power immediately

These beards, and other creative variations on chin whiskers, have become such a striking reflection of their wearers' personalities that it becomes hard to know whether the people made the facial hair famous, or the other way around. We do know this much is certain: the only rivals to these fabulous beards are the men sporting them.
