“I went to the library and learned how checks work. I found out that routing numbers are like zip codes: the checks are sent to the bank that correlates to the routing number. If I manipulate those numbers to a bank far away, it would take longer to get back to the bank, which gave me more time to write more bad checks.”

American-French con man, convicted felon, author, and security consultant

Frank William Abagnale Jr. is an American-French con man, convicted felon, author, and security consultant. He became widely known for saying that, as a teenager, he posed as a Pan American World Airways pilot, a doctor, a lawyer, and a university professor while traveling internationally and cashing fraudulent checks. His documented crimes mainly involved cheque fraud and petty theft aimed at individuals and small businesses. Those claims became the basis of his 1980 autobiography, Catch Me If You Can, written with Stan Redding. The book later inspired Steven Spielberg’s 2002 film of the same name, in which Leonardo DiCaprio played Abagnale, and a Broadway musical adaptation.
