Harry Markopolos

Harry M. Markopolos is an American forensic accounting and financial fraud investigator and former securities industry executive best known for initially discovering Bernie Madoff's Ponzi scheme in the late 1990s. From 1999 to 2008, Markopolos uncovered evidence that suggested that Madoff's wealth management business was a fraudulent Ponzi scheme. In 2000, 2001, and 2005, Markopolos alerted the U.S. Securities and Exchange Commission of his views, supplying supporting documents, but each time the SEC ignored him or gave his evidence only a cursory investigation.
