Biographical / Historical
Biographical / Historical
Pittsburgh Locomotive and Car Works was founded by Andrew Carnegie and T.N. Miller in 1865. Like most other railway companies, Pittsburgh Locomotive and Car Works was involved in designing and building light locomotive engines. Its first locomotive was finished in April, 1867, two years after the Civil War.
An energetic new superintendent, Daniel A. Wightman of Allegheny, Allegheny County, joined the company soon after its founding. The date of his employment with the company is unknown, but Wightman1s sketches of locomotives appear about 1874. In 1893, Wightman applied to the Commissioner of Patents for patent rights over his invention of an improvement in compound engines.
Wightman was the company's Superintendent and General Manager between 1895 and 1900. By the following year, 1901, the company had built a total of 2,400 locomotives. That same year, Pittsburgh Locomotive merged with a new corporation, the American Locomotive Company. The American Locomotive eventually closed the Pittsburgh plant after March, 1919.
Pittsburgh Locomotive Works was one of the first to produce really huge locomotives under Daniel A. Wightman. Many of these engines were sold to other Railway Companies throughout the United States.
