Klondike Haynes (1 January 1878 – 3 February 1949) was an African American boxer billed as "The Black Hercules" who declared himself the black heavyweight champion (not to be confused with the World Colored Heavyweight Championship, which he officially fought for just once and unofficially another time).

Childs won by a technical knockout when the referee stopped the fight in the fourth round of the scheduled six-round bout.

They fought again four times, as African American boxers were forced to fight one another often due to the color bar.

On 4 September 1898, Frank Childs lost his world colored heavyweight title to George Byers.

On October 28 of that year, they met in a rematch in Chicago in which Childs retained the black heavyweight title by K.O.-ing Klondike in the third round of a six-round contest.

Finally, he took back the Colored World Heavyweight Championship legitimately from Bryers on 16 March 1901 in Hot Springs, Arkansas, K.O.-ing him in the 17th round of a 20-round fight.

On 13 July 1909, in Pittsburgh's Bijou Theater, Langford "claimed" the title by facing and defeating Klondike, the erstwhile black heavyweight champ, with a newspaper decision in a six-rounder.
