John Helder Wedge (1793 – 22 November 1872) was a surveyor, explorer and politician in Van Diemen's Land (now Tasmania, Australia).[1]
Wedge was the second son of Charles Wedge of Shudy Camps, of Cambridgeshire, England.[1] John Wedge learned the basics of surveying from his father. Due to financial losses during the post-war depression in agriculture, Wedge and his brother Edward decided to migrate to Van Diemen's Land; before leaving London Wedge had obtained an appointment in the colony as assistant surveyor.
