Such a clickbaitey title. There were just a few.. THOUSAND.. causes that culminated in the 1929 crash, but saying one person caused it gets those clicks.
> Extremely successful both as an investment and as a commercial banker, Charles E. Mitchell was identified by contemporaries as the epitome of the unscrupulous “money changers” whose speculative dealings they felt played a major role in the Crash of 1929 and the ensuing economic collapse. This portrayal has been echoed and elaborated by historians and commentators down to the present day. In this article Dr. Huertas and Dr. Silverman demonstrate that Mitchell's activities, while sometimes ill-advised, were motivated by the economic “good sense” of the day and were not attributable to either rampant immorality or ungoverned greed. At the same time, they direct the attention of economic historians to the monetary policies of the Federal Reserve system in the 1920s and 1930s—in which Mitchell also played a role—and suggest that a more potent source of the Great Depression lies therein.
