John Massis

John Massis (4 June 1940–12 July 1988) was a Flemish bruiser and teeth-acrobat. His real name was Wilfried Morbee.

Massis specialized in bending iron with his teeth. He also performed stunts where he lifted cars, pulled trains and stopped motorbikes and even helicopters and hot air balloons with his teeth. This resulted in several entries in the Guinness World Records book.

He also funded a political party called "positieve radicalen" in Dutch or "positive radicals".

With waning media interest and diabetes undermining his condition, Massis ended up in a psychiatric hospital and committed suicide at the age of 48 on the 12th of July 1988.

In 2004 Johan Heldenbergh performed a play based on Massis' life: "Massis, the musical".
