Edward Dobson (1816/17? – 19 September 1908) was Provincial Engineer for the Canterbury Province from 1854 to 1868.
Edward Dobson was born in London, probably in 1816 or 1817. His parents were John Dobson, a merchant, and Elizabeth Barker. By the time he started his apprenticeship as an architect and surveyor in 1832, his father had died. He attended University College London and by 1843, he had graduated with certificates of honour in architecture and civil engineering.
From 1846 to 1849, he worked as railway engineer in Nottingham.
Emigration to New Zealand
With two of those children, George (1840–1866) and Arthur Dudley (1841–1934), he emigrated to Canterbury on the Cressy, one of the First Four Ships. The Cressy arrived in Lyttelton on 27 December 1850. Dobson was one of the original purchasers of land from the Canterbury Association.
Life with two young sons was challenging, and they were sent to their uncle, Reverend Charles Dobson, the vicar of Buckland in Tasmania. After three years, they returned to New Zealand and initially stayed with another uncle, the surveyor Alfred Dobson.
His wife followed on the Fatima and arrived in Lyttelton exactly one year later, on 27 December 1851. She had the other children with her: Mary Ann (1844–1913), Caroline (1845–1932), Edward Henry (1847–1934) and Maria Eliza (b. 1848). The remaining children were born in New Zealand: Robert (1852–1893), Emily Frances (1857–1943), Herbert Alex (1860–1948) and Collet Barker (1861–1926).
- New Zealand
In New Zealand, he was responsible for designing and overseeing the construction of many important public works, having been appointed provincial engineer in 1854. He designed a system of railways for the province, and by the time he retired, the Canterbury Great Southern Railway had reached Lyttelton and advanced as far south as the Selwyn River.
His son Arthur was apprenticed to him and an early task for the father and son team was to determine the depth of mud in Lyttelton Harbour. They then surveyed the Rangiora main drain, which resulted in reclaiming 20,000 acres (81 km2) of swamp land. Edward Dobson supervised the construction of the Ferrymead Railway, connecting the wharf in Ferrymead with Christchurch and opening on 1 December 1863. This was New Zealand's first public railway. A telegraph line was built along the rail corridor between Lyttelton and Christchurch, and when it opened on 1 July 1862, it was the first telegraph line in New Zealand. New Zealand Post celebrated the centenary with the publication of two commemorative stamps.
Edward Dobson's most important project was the superintendency of the Lyttelton Rail Tunnel, an engineering feat that is recognised with a Category I heritage protection by the New Zealand Historic Places Trust. His son Arthur prepared many of the sectional drawings. Shortly afterwards, the Ferrymead branch line was closed, and it became the first public railway to be disused in the country.
The chief surveyor, Thomas Cass, commissioned Arthur Dobson in 1864 to find out whether there is a suitable pass from the Waimakariri watershed to the West Coast. George and Arthur Dobson set out in March 1864, later to be joined by their brother Edward at Craigieburn. While George surveyed road lines there, Edward and Arthur proceeded to explore the high country. On the advice of West Coast Māori chief Tarapuhi, they found a pass that steeply descended to what became known as Otira; the route had long been used by Māori for trading pounamu. Arthur prepared a report, which included a sketch of the unnamed pass, and presented it to Cass.
Soon after, the discovery of gold triggered the West Coast Gold Rush. Edward Dobson was commissioned to examine every possible pass to the West Coast from the watersheds of the Waimakariri, Taramakau and Hurunui Rivers. After finishing his examination, he declared that "Arthur's pass" was by far the most suitable to get to the gold fields. The provincial government decided that a road was to be built between Christchurch and Hokitika, a distance of 156 miles (251 km), and Edward Dobson was put in charge of the project. The road was opened on 20 March 1866. The alpine pass became known as Arthur's Pass, with a nearby village and a later a national park also taking this name.
Dobson resigned as provincial engineer in 1868 and moved to Australia the following year. He undertook engineering work for a railway company in Melbourne, and water supply engineering work in Melbourne and Geelong. He returned to New Zealand in 1876.
- New Zealand again
In 1878, Edward Dobson went into a formal partnership with his son Arthur, which lasted until 1885. They were working on water supply schemes for Timaru and the Canterbury Plains. They surveyed the Midland Line over the Southern Alps and, in partnership with others, launched the Midland Railway Company. The venture was a failure, as it was underfunded. Eventually, the government took over the scheme, but the line between Christchurch and Greymouth was not finished until 1923.
In his later years, Edward Dobson concentrated on education. He had lectured since the 1860s, and his lectures to the Christchurch High School are regarded as "the first attempt to make Physical Science a branch of regular instruction in this colony". He published papers for the Philosophical Institute of Canterbury and the Institution of Civil Engineers in London, which awarded him the Telford Medal for the 1868–1869 session for a paper entitled The public works of the province of Canterbury, New Zealand.
Family and death
Life improved when Edward Dobson was appointed Provincial Engineer. He built a cob cottage in Sumner, and another house in central Christchurch in the block described by Tuam, Manchester and High Streets. He could afford to send his sons to Christ's College, then the best school in Christchurch.
His sons Sir Arthur Dudley Dobson and Edward Dobson (1847–1934) became prominent in New Zealand, both having been pioneer surveyors. Son George Dobson (1840–1866) was murdered by Richard Burgess and the other Maungatapu murderers.
Associate and Member of the Institute of Civil Engineers. Arrived in Canterbury 1850. First Provincial Engineer, 1854, and Engineer to the Moorhouse Tunnel. ‘His life’s desire was that his labours might be of benefit to his fellow Colonists’.
