#38: Jack Johnson
Johnson’s toughness came from his composure under fire and the pressure of racism and hostility. He faced violent crowds and unfair treatment yet fought with cool confidence. He absorbed punishment without panic, mentally breaking opponents. Johnson’s strength of mind and body made him one of boxing’s toughest pioneers.

In 1910, Johnson fought Jim Jeffries in the “Fight of the Century.” Facing a hostile crowd, he withstood Jeffries’ power and methodically wore him down, stopping him in the 15th. That victory showed Johnson’s toughness — thriving under enormous social and physical pressure to become the first Black heavyweight champion.
