This is Paul Cinquevalli: he could balance a man on one arm
above his head whilst juggling three balls with the other hand.
He was born in Prussia, now part of Poland, and his real name
was either Emile Otto Lehmann-Braun or Paul Kestner (sources
are unclear). When he was a child he ran away to join the circus
and worked as an aerial acrobat, but, after a serious accident
that left him lying in a hospital bed for eight months, he changed
his act and became a world famous juggler.
One of Paul Cinquevalli’s acts was called the ‘Human Billiard
Table’. Paul said this trick was his most difficult:
“…to play the game on my body took
me two years to learn but to balance the billiard balls
on top of the cue
cost me eight years practice so that the whole feat
represents ten years.”
