This list looks at great impostors from history; men and women who pretended to be someone they were not. We have omitted people who merely assumed false names (such as Frank Abagnale and Frédéric Bourdin) and focused entirely on impostors who claimed to be someone famous (with rather incredible success in some cases). Be sure to mention others you may know in the comments as this is a very interesting topic. This list is based on one sent in by Igor Itkin. It is released under the creative commons license as it relies heavily on Wikipedia for biographical information which is scant elsewhere.
