3. Charles Ponzi
Charles Ponzi was such an accomplished liar that a form of fraud, the Ponzi Scheme, is named after him. The scheme consisted of duping wealthy investors to invest in fake corporations created by Ponzi. He would then partially pay back investors with their own money; keeping a hefty bit for himself, of course. Active during the early 1900s, he was finally caught in 1920 and spent 14 years in prison.
