Known as "Killer", Wladek Kowalski wrestled for three decades between 1947 and 1977.

Trained by the legendary Lou Thesz, he was skilled as a pure wrestler. However, he is remembered mostly for the 1957 match in which he ripped Yukon Eric's ear. Though Eric never had a grudge against him, the incident helped his career as one of the biggest heels in the history of the sport.

After his retirement, he started a wrestling school in Massachussetts, where he trained the stars such as Big John Studd, Perry Saturn, John Kronus, Triple H, Chyna, Chris Nowinski, Giant Bernard, April Hunter, Frankie Kazarian, etc.
