Leo Koretz Leo Koretz Leopold Koretz (1879–1925) was an American lawyer and stockbroker who ran an elaborate Ponzi scheme in Chicago, called the "Bayano oil fraud," which garnered an estimated $30 million (about $400 million today) from dozens of investors in Chicago. The scheme used fraudulent claims of oil interests in Panama in a criminal career that predated his contemporary, Charles Ponzi. Koretz was so trusted and admired that after Ponzi's fraud was exposed in 1920, his investors nicknamed him "Our Ponzi," never suspecting they were being duped as well. Leopold Koretz was born to German Jewish parents on July 30, 1879
