Edward Snell (1820–1880) was a diarist, artist, civil engineer and surveyor, responsible for the design of the Geelong – Melbourne Railway for the Geelong and Melbourne Railway Company.

Snell was born 27 November 1820, in Barnstaple, Devon, grandson of William Snell, a serge manufacturer of Crediton, Devon and the son of Edward Snell, a silversmith, jeweler, watch and clockmaker in High Street Barnstable, and Elizabeth, née Stothert.

Snell was the eldest of four children, having three sisters, Rose Emily (known as Emily), Emma and Elizabeth (known as Lizzie). His father died in 1827 at age 33, when Snell was only aged six, leaving their mother to raise them in financial difficulty despite the £1500 realized from the sale of the family business, High Street shop and house above it. Snell's maternal grandfather, Abel Stothert, was a cutler from Shaftesbury, whose brother was George Stothert, who established the Stothert ironmongery business in Bath around 1785, and his son George junior (1786-1858) who established the Horse Street Foundry in 1815, which subsequently grew into the important British engineering firm Stothert & Pitt. George Stothert played an important role in encouraging and helping his young cousin Edward Snell in his engineering career.

At the age of 14 he was apprenticed as an engineer and millwright to the Stothert's Bath foundry in the renamed Newark Street under George's younger half-brother Henry Stothert, completing his indenture on 16 March 1842. Most of his work was on projects around Bath, but sometimes extending as far as Newbury. Henry arranged for him to take up a position at the Avonside Ironworks in Bristol in May 1842, which had been established by Henry in 1837. He was not happy here, however, and gave notice after just three weeks, complaining of the low wages (20 shillings per week) and the tyrannical regime in the workshop.

Despite the resulting animosity from both Henry and George Stothert, George used his influence with the Locomotive superintendent Daniel Gooch to gain a position for Snell at the Great Western Railway Company Swindon workshops on 28 February 1843. Here he had the position of head draughtsman and then rose to deputy works manager. He stayed at the GWR in Swindon for six years apart from a short stint in 1844 at Penn's marine engineering works in Greenwich.

A reduction in wages brought about by the post railway mania crash of 1848-9, caused him to decide to emigrate to Australia at the age of 29 with his friend Edward Prowse, having considered America. He arrived in Adelaide on the Bolton on 29 November 1849, recording in his diary: When I was 21 I calculated on making a small fortune by the time I was 30 but have made little headway in that line as yet. Snell spent some time in South Australia surveying and painting, spending three months on the Yorke Peninsula in 1850, then around Lake Alexandrina at the Murray River mouth. He produced a Plan for the Grand Junction Canal between Adelaide and the North Arm in August 1851.

On 12 March 1852 he arrived at the Castlemaine diggings where he amassed £341 worth of gold in five months. Snell married Charlotte Elizabeth Bayley in Geelong on 23 June 1853, and the pair had 9 children, the first of whom Emily Charlotte died as an infant, but the other eight survived to adulthood.

It was Snell's work as engineer for the Geelong and Melbourne Railway Company, from 1853 until he resigned in October 1857, that established his fortune, for which he had been paid more than £17,000. His designs included a substantial terminal station and workshops at Geelong (which were only partly realised).
