Westinghouse Park is a city-block sized municipal park in Pittsburgh, Pennsylvania. The park land is the former estate of George Westinghouse, an American entrepreneur and engineer, and his wife Marguerite. With an area of about 10 acres, it was the site of his mansion known as Solitude. At this house, Westinghouse worked with his engineers, including Nikola Tesla, and entertained notable people of the day, including scientist William Thomson (Lord Kelvin), and congressman and later president William McKinley. Close by was another building, a carriage house, that housed his private laboratory in the basement. There, he developed some of his residential electric lighting technology, installing a generator and running cables to the main house, with wires that were left exposed on the interior walls, so as not to cut into the woodwork. Also there, Westinghouse invented methods to control and transmit natural gas for both industrial and residential consumers. In the winter of 1883/1884, seeking a source of natural gas in his own "back yard," Westinghouse ordered drilling on his estate. When gas was struck on May 22, 1884, a blowout resulted in the uncontrolled release of gas for about a week. Westinghouse devised a way to cap the well. An illumination test was conducted by igniting the gas jet at the top of a tall pipe. It initially produced a 100-foot flame that illuminated a mile-wide area to a brightness sufficient to read a newspaper. This well was designated as "Westinghouse Well No. 1" or "Old No. 1" to distinguish it from several other wells that were drilled in the area. Eventually, several natural gas derricks towered above the estate's Victorian gardens. In modern times there is no above-ground trace left of these derricks. History The park's history began when Westinghouse, upon his death in 1914, bequeathed the North Point Breeze mansion to his son, who in turn sold the property in 1918 to the Engineers' Society of Western Pennsylvania. The Society's intent was to establish both a city park and a memorial to Westinghouse there. As per a deed stipulation, the house was razed in 1919 and the park was developed; the Westinghouse Memorial, however, was erected a few miles away in Schenley Park. Westinghouse Park today is maintained by the City of Pittsburgh. The park hosts a well-used children's playground, a basketball court, and a community building used for meetings and as a 14th Ward polling (voting)
