George Westinghouse, Jr. (October 6, 1846 - March 12, 1914) was an American entrepreneur and engineer who invented the railway air brake and was a pioneer of the electrical industry. Westinghouse was one of Edison's main rivals in the early implementation of the American electricity system. Westinghouse's system ultimately prevailed over Edison's insistence on direct current. In 1893, the Westinghouse company was awarded the contract to set up an AC network to power the World's Columbian Exposition in Chicago, giving the company and the technology widespread positive publicity. He also received a contract to set up the first long-range power network, with AC generators at Niagara Falls producing electricity for distribution in Buffalo, New York, 25 miles away. He also developed steam turbines for maritime propulsion. He remained productive and inventive almost all his life. He died in 1914, at age 67, and was buried in Arlington National Cemetery as a Civil War veteran. No photographer credited, undated.
