The Gilded Age was based on industrialization, especially on the development of heavy industry: factories, railways, coal mines. Steel production in the United States during this period exceeded total steel production in the UK, Germany, and France.
Inventors and scientists have contributed to the modernization of America. In 1882, Edison built the first power station in the United States. In 1894, the aggregated value of the industrial products of the United States exceeded the industrial production of England and Germany combined. In 1876, the Bell telephone was presented at the World Exhibition in Philadelphia, and the Chicago exhibition in 1892 approved the status of the United States - the first country in terms of technique.
