George Woodroffe Goyder (24 June 1826 – 2 November 1898) was a surveyor in the Colony of South Australia during the latter half of the nineteenth century. He rose rapidly in the civil service, becoming Assistant Surveyor-General by 1856 and the Surveyor General of South Australia in 1861. He is remembered today for Goyder's Line of rainfall, a line used in South Australia to demarcate land climatically suitable for arable farming from that suitable only for light grazing, and for the siting, planning and initial development of Darwin, the Northern Territory capital and principal population centre. However, Goyder was an avid researcher into the lands of South Australia (including the present-day Northern Territory) and made recommendations to a great number of settlers in the newly developing colony, especially to those exploiting the newly discovered mineral resources of the state. Career Early life Goyder was born in Liverpool, England to Sarah and David George Goyder, the latter a Swedenborgian minister and physician. He moved to Glasgow with his family where he worked with an engineering firm and studied surveying. In 1848, at the age of 22, Goyder followed his sister and brother-in-law, George Galbraith MacLachlan (c. 1842 – 19 March 1873), to Sydney. He spent time working with an auctioneering firm and moved to Adelaide in 1851, obtaining work as a civil service draftsman. Assistant to Surveyor-General Goyder was appointed Assistant Surveyor-General circa 1856. In this period he made many expeditions into the outback regions of South Australia, thinking that the water in lakes he saw at the time was fresh and permanent, rather than exceedingly erratic. He wrote many letters to newly established pastoralists who had moved into the arid regions for the state's north, and also surveyed the newly establishing mining industry in the Flinders Ranges. In 1861 he was appointed Surveyor-General. His early years in the role were very difficult, especially his efforts to help establish settlement in the Northern Territory by supervising the establishment of the pastoral leaseholds that continue to the present day. Pastoralists were hit by a major drought in the middle of the decade and complained severely, with many forced to move even relatives away from their cattle stations by the end of 1865. Goyder was also faced with the despair of his wife, Frances Mary Smith, who suffered the loss of twins at birth during George's long travels in the outback. Goyder resigned
