Mark Twain and Charles Dudley Warner coined the term "Gilded Age" in their novel, The Gilded Age: A Tale of Today, which was published in 1873. The term gilded is an adjective meaning covered with gold or with a substance that looks like gold, and the term was therefore used to satirize the ostentatious display of wealth that characterized the time period from approximately 1878 to 1889. The growth of industry and the production of steel and iron brought great fortunes for businessmen such as Andrew Carnegie and John D. Rockefeller, who were sometimes pejoratively referred to as robber barons, due to the public notion that such people became rich through ruthless business practices.
