Richard Dennis was a long time commodities trader who earned the nickname the “Prince of the Pit.” He began his career as a runner at the Chicago Mercantile Exchange at the age of 17 and a few years later was trading for his own account from the floor of the Chicago Board of Trade Building. His rise to fame came when he took a $400 trading account and turned it into $200 million within ten years. He became more legendary when he embarked on a famous experiment to teach ordinary people with no trading backgrounds how to trade.
