John Pierpont Morgan, a name very recognizable today as J.P. Morgan, was an influential banker in the late nineteenth and early twentieth century. Morgan's banks played important roles in the growth and corporate finances of many large companies, including a number of mergers of smaller corporations to form large, dominant companies such as General Electric, U.S. Steel, and AT&T. These mergers involved the channeling of funds into corporate stocks and bonds and resulted in the formation of some of the wealthiest and most powerful companies in the world.
