In the Panic of 1907, which U.S. financier led the private rescue effort?

In the Panic of 1907, J. P. Morgan led the private rescue effort.

Morgan gathered bankers in New York and used his influence, money, and financial network to stabilize troubled institutions. The crisis had intensified after a failed attempt to corner shares of United Copper Company, followed by runs on banks and trust companies.

Morgan and other financiers negotiated loans, purchased securities, and helped arrange support for the Trust Company of America. His actions helped contain the panic, but the episode also exposed how dependent the United States was on a single powerful private banker during emergencies.

The Panic of 1907 contributed to political support for creating the Federal Reserve System. The Federal Reserve was established in 1913, so it did not exist to manage this particular crisis.
