Tom Wills
Wills grew up with Indigenous Australians.  He spoke the language of the people who lived near him and played with the children.  It has been suggested that Australian Rules Football is based in part on Marn Grook, an Aboriginal game with some similar rules to Australian Rules Football. Because the indigenous people Wills played with as a child would have played Marn Grook, Wills would have been influenced by this game when creating the rules for Australian Rules Football.
