Fossett then became a successful commodities salesman in Chicago, first for Merrill Lynch in 1973, where he proved a highly successful producer of commission revenue for himself and that firm. He began working in 1976 for Drexel Burnham, which assigned him one of its memberships on the Chicago Board of Trade and permitted him to market the services of the firm from a phone on the floor of that exchange. In 1980, Fossett began the process that eventually produced his enduring prosperity: renting exchange memberships to would-be floor traders, first on the Chicago Board Options Exchange.[1][12]
