This is a cradle-to-grave biography of Mickey Walker, former welterweight (1922-1926) and middleweight champion (1926-1931) of the world, one of the greatest fighters in ring history. He fought at a time when boxing was a major sport with only eight championships, and he held two of them over a nine-year period. He fought at a time when each weight division was jammed with good fighters, and he fought them all from welterweight up to heavyweight, frequently being outweighed 20 to 30 pounds. Walker was also a great personality who loved life and lived it to the fullest. He was married seven times to four different women, and he cavorted with movie stars and mobsters. When his boxing career ended in 1935, Walker ran saloons in various locations and eventually became an artist of some standing. He died in 1981 at age 79.
