Jesse Livermore

One of the most famous speculators in Wall Street history, known for making and losing several multimillion-dollar fortunes between the early 1900s and 1940. Livermore shorted the market before both the 1907 panic and the 1929 crash, earning him the nickname "The Great Bear of Wall Street." His trading philosophy, documented in Edwin Lefevre's classic "Reminiscences of a Stock Operator," remains widely read by traders today for its timeless insights on market psychology, patience, and risk management.
