– Frank Abagnale

Frank William Abagnale Jr. (born April 27, 1948) is an American security consultant, author, and convicted felon who committed frauds that mainly targeted individuals and small businesses. He later gained notoriety in the late 1970s by claiming a diverse range of workplace frauds, many of which have since been placed in doubt. In 1980, Abagnale co-wrote his autobiography, Catch Me If You Can, which built a narrative around these claimed frauds. The book inspired the film of the same name directed by Steven Spielberg in 2002, in which Abagnale was portrayed by Leonardo DiCaprio. He has also written four other books. Abagnale runs Abagnale and Associates, a consulting firm.
