Mark Edward Whitacre is an American business executive who came to public attention in 1995 when, as president of the Decatur, Illinois-based BioProducts Division at Archer Daniels Midland (ADM), he became the highest-level corporate executive in U.S. history to become a Federal Bureau of Investigation (FBI) whistleblower. For three years (1992–95), Whitacre acted as a cooperating witness for the FBI, which was investigating ADM for price fixing. In the late 1990s Whitacre was sentenced to 9 years in federal prison for embezzling $9.5 million from ADM at the same time he was assisting the federal price-fixing investigation.
