The sparring partners of Jack Johnson

[Caractacus]

Who did he use to get ready for some of his big fights?
( and for his not-so-big fights too)

[Caractacus]

In 1910 .
Johnson had sparred with:
( for his upcoming fight with Jim J. Jeffries

Denver Jack Geyer
George "Kid" Cotton
Walter Monahan
Monte(Marty) Cutler
Al Kaufmann
Dave Mills

[Caractacus]

In 1912 for his fight with Fireman Jim Flynn.
Johnson had as sparring partners:

Calvin Respress
Monte(Marty) Cutler
George DeBray
Harry Wills

[Caractacus]

I think in his 1927 autobiography,Jack Johnson mentioned while in Australia training for the title fight with Tommy Burns,
he had in his corner or trained or sparred with.

Rudolph Unholz ( a South African HW)
Jack and George Walker (the Walker Bros.)

he also mentions 2 other individuals in his corner
but I havent been able to find out yet if they were boxers.
Bobby Bryant
Leo O'Donnell
(anyone know if these last two were boxers?)

[Caractacus]

Jack Johnson also had sparred with;

Joe Walcott (1896-in Boston for 2 months)
Frank Childs-c.1898
Tom Sharkey-1901
Kid Carter-1901

[Ambling Alp II]

Gunboat Smith for the Ketchel fight.

[Caractacus]

also for the Ketchel fight was Denver Jack O'Keefe (who later claimed Johnson was practicing being knocked-down.)
and I think Bob Armstrong may have possibly been one or at least in Johnson's corner.
although of course Armstrong was in Jim J. jeffries corner for the Reno fight.

I found out who Bobby Bryant was.
He wasn't a boxer but a friend and a Horse-trainer that Jack Johnson knew
from his earlier days in Boston.
He also ran off with Johnson's second wife,
which Jack Johnson talks about in his autobiography.
