Episode Two
John Arthur ("Jack") Johnson
(March 31, 1878 – June 10, 1946) nicknamed the “Galveston Giant”, was an American boxer, the first black world heavyweight boxing champion (1908-1915).
Johnson was born in Galveston, Texas, the third child and first son of Henry and Tina "Tiny" Johnson, former slaves who worked at blue-collar jobs to raise six children and taught them how to read and write. Jack Johnson had just five years of formal schooling. Johnson's father was born a slave in Tennessee. He dropped out of school after five or six years of education, to get a job.
Johnson's boxing style was very distinctive. He developed a more patient approach than was customary in that day: playing defensively, waiting for a mistake, and then capitalizing on it. Johnson always began a bout cautiously, slowly building up over the rounds into a more aggressive fighter. He often fought to punish his opponents rather than knock them out, endlessly avoiding their blows and striking with swift counters. He always gave the impression of having much more to offer and, if pushed, he could punch powerfully.
Johnson's style was very effective, but it was criticized in the press as being cowardly and devious. By contrast, World Heavyweight Champion "Gentleman" Jim Corbett, who was white, had used many of the same techniques a decade earlier, and was praised by the press as "the cleverest man in boxing".
By 1902, Johnson had won at least 50 fights against both white and black opponents. Johnson won his first title on February 3, 1903, beating "Denver" Ed Martin over 20 rounds for the World Colored Heavyweight Championship. His efforts to win the full title were thwarted, as world heavyweight champion James J. Jeffries refused to face him then. Black and white boxers could meet in other competitions, but the world heavyweight championship was off limits to them. However, Johnson did fight former champion Bob Fitzsimmons in July 1907, and knocked him out in two rounds.

Johnson finally won the world heavyweight title on December 26, 1908, when he fought the Canadian world champion Tommy Burns in Sydney, after stalking Burns around the world for two years and taunting him in the press for a match. The fight lasted fourteen rounds before being stopped by the police in front of over 20,000 spectators. The title was awarded to Johnson on a referee's decision as a T.K.O, but he had clearly beaten the champion. Johnson constantly mocked both Burns and his ringside crew, while receiving every kind of racial and other slur from them and members of the crowd. Every time Burns was about to go down, Johnson would hold him up, beating an already helpless man.
After Johnson's victory over Burns, racial animosity among whites ran so deep that Jack London called out for a "Great White Hope" to take the title away from Johnson. As title holder, Johnson thus had to face a series of fighters billed by boxing promoters as "great white hopes", often in exhibition matches. In 1909, he beat Frank Moran, Tony Ross, Al Kaufman, and the middleweight champion Stanley Ketchel. The match with Ketchel was keenly fought by both men until the 12th and last round, when Ketchel threw a right to Johnson's head, knocking him down. Slowly regaining his feet, Johnson threw a straight to Ketchel's jaw, knocking him out, along with some of his teeth, several of which "supposedly" were embedded in Johnson's glove. His fight with Philadelphia Jack O'Brien was a disappointing one for Johnson: though weighing 205 pounds (93 kg) to O'Brien's 161 pounds (73 kg), he could only achieve a six-round draw with the great middleweight.
