Jess Willard (December 29, 1881 in the town of St. Clere, Pottawatomie County, Kansas - December 15, 1968 in Los Angeles, California) was a world Heavyweight boxing champion.

A working cowboy, he did not begin boxing until he was almost thirty years old.

Despite his late start, Jess Willard proved successful as a boxer, defeating top-ranked opponents to earn a chance to fight for the championship. On April 5, 1915 in front of a huge crowd at the Vedado Racetrack in Havana, Cuba, in the 26th round he knocked out champion Jack Johnson to win the World Heavyweight Boxing Championship.

Johnson spread rumors that he took a dive , but Willard is widely regarded as winning fairly. Johnson found that he could not knock out the giant Willard, who fought as a counterpuncher, making Johnson do all the leading. Johnson began to tire after the 20th round, and was visibly hurt by heavy body punches from Willard in rounds preceding the 26th round knockout. Following the fight, Willard was heralded as "The Great White Hope".

At 6' 6 1/2" (2 m) and 245 lbs (111 kg), Jess Willard was the tallest and the largest heavyweight champion in boxing history, until the 6'7" Vitali Klitschko and 270 lb Primo Carnera won the title on June 26, 1999[Klitschko" target="_blank">http://en.wikipedia.org/wiki/Vitali_Klitschko] and June 29, 1933 respectively[http://en.wikipedia.org/wiki/Primo_Carnera]. The 37-year-old champion lost his title to _Jack Dempsey on July 4, 1919 in Toledo, Ohio. Dempsey knocked Willard down for the first time in his career with a left hook in the first round. Dempsey knocked Willard down 7 times in the first round, winning the title when Willard was unable to continue after the third round. In the fight Willard suffered a broken jaw, cheekbone, and ribs as well as losing several teeth. Rumors spread that Dempsey had plastered his hands to make them harder, but Dempsey has sworn that this never happened.

Willard parlayed his boxing fame into an acting career of a sort. He acted in a vaudeville show, had a role in Buffalo Bill's Wild West Show, and starred in a 1919 feature film The Challenge of Chance. In 1933, he appeared in a bit part in a boxing movie, The Prizefighter and the Lady, with Max Baer and Myrna Loy.

On his passing in 1968, Jess Willard was interred in the Forest Lawn, Hollywood Hills Cemetery in Los Angeles, California.

In 2003, he was inducted posthumously into the International Boxing Hall of Fame.
