Richard J. Dennis, a commodities speculator once known as the "Prince of the Pit," was born in Chicago, in January, 1949. In the early 1970s, he borrowed $1,600 and reportedly made $200 million in about ten years. When a futures trading fund under his management incurred significant losses in the stock market crash of 1987 he retired from trading for several years. He has been active in Democratic and Libertarian political causes, most notably in campaigns against drug prohibition.
Dennis became an order runner on the trading floor of the Chicago Mercantile Exchange at age 17. A few years later, he began trading for his own account at the MidAmerica Commodity Exchange, an entry-level floor where "mini" contracts were traded. To circumvent a rule requiring traders to be at least twenty-one years of age, he worked as his own runner, and hired his father, who traded in his stead in the pit.
Dennis earned a bachelor's degree in philosophy from DePaul University, then accepted a scholarship for graduate study in philosophy at Tulane University, but then changed his mind, and returned to trading. He borrowed $1,600 from his family, which after spending $1,200 on a seat at the MidAmerica Commodity Exchange left him $400 in trading capital. In 1970, his trading increased this to $3,000, which he described as "compared to $400 ... a real grubstake", and in 1973 his capital was over $100,000. He made a profit of $500,000 trading soybeans in 1974, and by the end of that year was a millionaire, just short of twenty-six years of age.
Dennis profited, as he bought successively new weekly and monthly highs in the trending inflationary markets of the 1970s, an era of repeated crop failures and the "Great Russian Grain Robbery" of 1972, when agents of the Soviet Union secretly purchased 30% of the U.S. wheat crop in the space of a few weeks. This set the stage for solid, sustained price trends in both directions for the next several years, a period in which "anyone with a simple trend-following method and a dart board could make a million dollars".
