Biography

John Batman (1801 – 1839) was born in NSW, and settled in Van Diemen's Land in the 1820s. Receiving a land grant near Ben Lomond, he received an additional grant for his role in the capture of bushranger Matthew Brady. 
Brady took part in the capture and killing of aboriginal people during the "Black War". His relationship with aboriginal people is nowadays seen as controversial, despite his adoption of an aboriginal child. Fellow settler and neighbour of Batman, the colonial artist John Glover, wrote that he was "a rogue, thief, cheat and liar, a murderer of blacks and the vilest man I have ever known".

Batman went on to become a founding settler at Port Philip, the future Melbourne, and his contributions there, including what decisions about the settlement's location can be credited to him, and a dubious treaty with aboriginal people to "rent" their land, are now largely discredited.
He died at Melbourne in 1837.
