Mike Tyson was the youngest Boxer to win the heavyweight title, and the first to hold all 3...he was only 20 years old when he did it.
"Iron Mike," as he was called, won his first 19 professional fights by Knockout, 12 coming in the first round. He was a machine, and after knocking out Michael Spinks (then regarded as the best professional fighter) in 91 seconds in the 1st Round, he became a legend.
