Answer:
Captains of industry during the Gilded Age were Andrew Carnegie, Cornelius Vanderbilt, John D. Rockefeller, among others.
Explanation:
The Gilded Age (named after Mark Twain's novel) was a period of greed and political corruption during the outburst of Industrialization and Capitalism in the United States. The industries' magnates were called "captains of industry" by many optimists and "robber barons" by less optimistic viewers. These industrialist leaders took monopoly of certain areas of production such as steel (Andrew Carnegie) and transportation (Cornelius Vanderbilt). They were referred to as "robber barons" because of their unscrupulous actions and greed. It was called the Gilded Age because what seemed goodwilled men were actually not that good underneath.
Gilded: covered thinly with gold paint (figurative meaning: something may seem like gold on the outside but it is different underneath)
