Which U.S. trust company’s collapse helped trigger the Panic of 1907?

The collapse of the Knickerbocker Trust Company helped trigger the Panic of 1907.

Knickerbocker Trust suspended operations on October 22, 1907, after a failed speculation involving copper shares undermined public confidence. Depositors withdrew funds, and a broader banking panic spread through New York and other parts of the United States.

Financier J. P. Morgan organized private support for threatened institutions and helped stabilize the financial system. The panic exposed weaknesses in the U.S. banking structure and contributed to political support for creating the Federal Reserve System in 1913. The episode is sometimes called a stock-market crash, but it was also a banking and credit crisis.
