Lennart Green

Lennart Green doctor turned card magician.

Green's act [is] an heroic display of skill masked by well feigned clumsiness.

In 1998 a fumbling swedish doctor arrive on the international magic scene as he took the stage in the close up competition of the FISM or world championship of magic. As Lennart Green began his act he seemed like a likely candidate for disqualification due to lack of training, but as he continued he stumped the judges. The esteemed master magicians judging him became convinced that Lennart was using a trick deck, since there was no other way that he could have done the unbelievable things he did. SO in the end they did disqualify him, not for incompetence but for cheating the magicians.
As it was Lennart hadn't used a trick deck. He had instead been practicing and developing an entire new method for handling cards that would completely alter what magicians believed what could be done with a deck of card.
At the next FISM Lennart Green entered again, performed pretty much the same act, and won.
Here he is. Enjoy.
