Kolov left Bulgaria and moved to the United States at the age of 13. In 1937, Kolov defeated then European Heavyweight Champion, American
Al Pereira, only for Pereira to win the title back and for Kolov to reclaim it, before losing it in turn to
Joe Savoldi. Kolov started his career as a wrestler by taking part in the organised wrestling matches between the
workers. He later won the tournament in the circus "Victoria" in 1914, when the director of the circus invited people from the public to compete and check their physical power with the star Jeff Lawrence "The Cyclope". Kolov accepted the challenge and he succeeded in overpowering the 233 pound wrestler. He won against many famous wrestlers from that time such as Jeff Lawrence, Stanislaus Zbyszko, Jack Shirey (also called "The Lightning Man"),
Rudy Dusek, Jo Stecker,
Ed "Strangler" Lewis, and
Jim Browning.
Wins Kolov had over 1,500 official matches. == Return to Bulgaria ==
