The four biggest robber barons of the late 19th century were John D. Rockefeller, who dominated the oil industry through Standard Oil; Andrew Carnegie, a key figure in the steel industry with Carnegie Steel; Cornelius Vanderbilt, known for his control over the railroad and shipping industries; and J.P. Morgan, a powerful banker who consolidated various industries, including steel and electricity, through financial mergers. These individuals significantly shaped American industry and economy, often employing ruthless business practices to eliminate competition and maximize profits.
