Sonny Liston (1930–1970) was one of the most intimidating heavyweight champions in history, known for his thunderous left jab and devastating power before his shocking losses to Muhammad Ali.
Liston's aura of invincibility was so complete that most observers — including the boxing establishment — expected him to destroy the young Cassius Clay. What followed changed boxing history forever.
