WOLF RUVINSKINS (1921 - 1999)
 
Was a Latvian-Mexican actor and professional wrestler, El Lobo de Letonia (The Latvian Wolf). His parents emigrated to Argentina in 1923, living in poverty, and wrestling professionally as a way to help provide for the family. 
In the ring, Ruvinskis played a savage, vicious Rudo (the bad guy) character, which was very successful and managed to draw large crowds wherever he went, as everyone wanted the técnico (good guy) to defeat the savage El Lobo de Letonia. 
He was introduced to the Mexican Lucha Libre cinema playing a masked character he created called Neutrón. He also belongs to the Golden Age of Mexican cinema.
