8. Sherron Watkins Enron (2002)
Enron Corp’s whistleblower Sherron Watkins was selected as one of three “Persons of the Year 2002” by Time. She had cautioned Enron CEO about accounting irregularities in financial reports, before exposing details of the financial scandal to the world at large. Her allegations proved to be true as Enron became the biggest corporate bankruptcies of all times. The auditor of the company Arthur Anderson also became a casualty of this scandal as he could not recover from the fallout of failing to point out the accounting shenanigans at Enron.
