1929 Wall Street crash at the New York Stock Exchange

In late October 1929, panic selling on the New York Stock Exchange culminated in dramatic market collapses on Black Thursday (October 24) and Black Tuesday (October 29) at the Exchange building. The NYSE, located at 11 Wall Street, was the epicenter of the crash that precipitated a prolonged stock market downturn and helped usher in the Great Depression. Brokerage firms and banks headquartered in the Wall Street area suffered massive losses, and the events prompted new financial regulations in subsequent years.
