Which financier became the central rescuer during the Panic of 1907?

J. P. Morgan became the central private-sector rescuer during the Panic of 1907.

The panic began after a failed attempt to corner the stock of United Copper Company helped trigger runs on trust companies and banks. Depositors demanded cash, while financial institutions became increasingly reluctant to lend to one another. The crisis spread through New York's financial system and threatened the wider economy.

Morgan used his banking network, personal authority, and access to information to organize emergency lending and coordinate support for troubled institutions. He and other financiers examined balance sheets, supplied funds, and helped arrange rescues. His library became a famous meeting place during the negotiations.

The episode demonstrated how heavily the United States depended on a private banker during a systemic emergency. It helped build political support for a formal central bank, leading to the creation of the Federal Reserve in 1913. Morgan did not act as a government official, and the panic was not caused by a stock-market crash alone; bank runs and a credit shortage were central features.
