George Ernest Hamilton CE (ca.1800 – 8 October 1872) was a British civil engineer who played a leading role in development of the Colony of South Australia.
[5] He was Chief Engineer for the Waterworks Department 1857–1858, and responsible for the Torrens Gorge weir near Campbelltown which failed in July 1858, its first year of operation.
[6] Hamilton was called as a witness in 1859 when it was discovered that the contractors Frost & Watson had skimped on materials for the dam wall, but came in for a share of the blame[7] and resigned, to be replaced by John England.
He and his son, architect Edward Angus Hamilton, were involved in constructing the Kadina to Wallaroo railway, completed in 1866.
[10] Their partnership was dissolved in 1866 when George was appointed to the Strathalbyn and Middleton Railway and E. A. Hamilton to the firm of Wright & Woods,[11] (then in 1868 second-in-charge of the Colonial Architect's Department, MLA for Kadina 1870–1871 and later moved to South America).
