A strong young man, weighing 130 kg, he joined the circus as a wrestler and toured in the United States, Mexico and Argentina.

He used to get into the ring with a giant Star of David painted on his shirt, and many young Jews identify with his character.

When the rest of the wrestlers returned to the United States, Kozalchik stayed in Poland to start a family.

He opened a kiosk in Holon and later on returned to be an active strongman and a professional wrestler under the name of Samson Eisen.
