The railway air brake was invented by George Westinghouse of New York state in 1869. Soon after, he moved to Pittsburgh, Pennsylvania, where he established the Westinghouse Air Brake Company (WABCO) on September 28, 1869.
After having manufactured equipment in Pittsburgh for a number of years, he began to construct facilities and plants East of the city where homes for his employees were built. In 1889, the air brake manufacturing facility was moved to Wilmerding, Pennsylvania, and the company's general office building was built there in 1890.
WABCO's direct successor companies include WABCO Vehicle Control Systems, a commercial vehicle air brake manufacturer; and Wabtec, a railway equipment manufacturer, which have been owned and operated independently of each other since the mid-twentieth century.

“A multitude of little superfluous precautions engender here a population of deputies and sub-officials, each of whom acquits himself with an air of importance and a rigorous precision, which seemed to say, though everything is done with much silence, “Make way, I am one of the members of the grand machine of state.””
—Marquis De Custine (1790–1857)
“People who abhor solitude may abhor company almost as much.”
—Mason Cooley (b. 1927)
