From 1871, George and Marguerite Westinghouse maintained a large home in Pittsburgh called Solitude, building up from an existing house on land purchased by George in 1871. They were part of a social class of very rich local industrialists and money managers including neighbors and associates Henry Clay Frick, Henry J. Heinz, William Thaw, Andrew Mellon, and Richard Beatty Mellon, and the brothers Andrew Carnegie and Thomas Carnegie. Their guests included Nicola Tesla, Lord Kelvin, and congressman (and future president) William McKinley.
