BERNIE MADOFF

1938-present
Where to begin? Madoff masterminded the ur-Ponzi scheme, and America is still reeling.

ALDRICH AMES

1941-present
Ames was a CIA agent for 32 years before he was arrested in 1994 for selling state secrets to the Soviet Union since 1985. He blamed his actions on financial troubles stemming from alimony payments to his ex-wife, who left him when she found out he wanted to marry his longtime mistress.

KENNETH LAY

1942-2006
As the chairman of Enron, Lay refined the Ponzi scheme into corporate heist, convincing investors that his company made billions more a year than the company actually earned a year before it was revealed to be a scam in late 2001. He was convicted on 10 counts, including fraud, in 2006, but he died of a heart attack before serving any time behind bars.

FRANK ABAGNALE

1948-present
The notorious check-forging teen con man's autobiography inspired Leo's character in 2002's Catch Me if You Can.

CHRISTOPHE ROCANCOURT

1967-present
Rocancourt has assumed countless identities over the years, including, most infamously, that of a French heir to the Rockefeller fortune.

Chump change!
