Regency Personalities Series
In my attempts to provide us with the details of the Regency, today I continue with one of the many period notables.
Isambard Kingdom Brunel
9 April 1806 – 15 September 1859
Isambard Kingdom Brunel
The son of French civil engineer Sir Marc Isambard Brunel and Sophia Kingdom, Isambard Kingdom Brunel was born on 9 April 1806 in Britan Street, Portsea, Portsmouth, Hampshire, where his father was working on block-making machinery. The family moved to London in 1808 for his father’s work. Brunel had a happy childhood, despite the family’s constant money worries, with his father acting as his teacher during his early years. His father taught him drawing and observational techniques from the age of four and Brunel had learned Euclidean geometry by eight. During this time he also learned fluent French and the basic principles of engineering. He was encouraged to draw interesting buildings and identify any faults in their structure.
When Brunel was eight he was sent to Dr Morrell’s boarding school in Hove, where he learned the classics. His father was determined that Brunel should have access to the high-quality education he had enjoyed in his youth in France; accordingly, at the age of 14, the younger Brunel was enrolled first at the College of Caen in Normandy, then at Lycée Henri-Quatre in Paris.
When Brunel was 15, his father, who had accumulated debts of over £5,000, was sent to a debtors’ prison. After three months went by with no prospect of release, Marc let it be known that he was considering an offer from the Tsar of Russia. In August 1821, facing the prospect of losing a prominent engineer, the government relented and issued Marc £5,000 to clear his debts in exchange for his promise to remain in Britain.
When Brunel completed his studies at Henri-Quatre in 1822, his father had him presented as a candidate at the renowned engineering school École Polytechnique, but as a foreigner he was deemed ineligible for entry. Brunel subsequently studied under the prominent master clockmaker and horologist Abraham-Louis Breguet. In late 1822, having completed his apprenticeship, Brunel returned to England.
Brunel worked for several years as an assistant engineer on the project to create a tunnel under London’s River Thames, with tunnellers driving a horizontal shaft from one side of the river to the other under the most difficult and dangerous conditions. Brunel’s father, Marc, was the chief engineer, and the project was funded by the Thames Tunnel Company.
The composition of the riverbed at Rotherhithe was often little more than waterlogged sediment and loose gravel. An ingenious tunnelling shield designed by Marc Brunel helped protect workers from cave-ins, but two incidents of severe flooding halted work for long periods, killing several workers and badly injuring the younger Brunel. The latter incident, in 1828, killed the two most senior miners, and Brunel himself narrowly escaped death. He was seriously injured, and spent six months recuperating. The event stopped work on the tunnel for several years.
Brunel is perhaps best remembered for designing the Clifton Suspension Bridge in Bristol. Spanning over 700 ft (210 m), and nominally 200 ft (61 m) above the River Avon, it had the longest span of any bridge in the world at the time of construction. Brunel submitted four designs to a committee headed by Thomas Telford, but Telford rejected all entries, proposing his own design instead. Vociferous opposition from the public forced the organising committee to hold a new competition, which was won by Brunel.
Work on the Clifton bridge started in 1831, but was suspended due to the Queen Square riots caused by the arrival of Sir Charles Wetherell in Clifton. The riots drove away investors, leaving no money for the project, and construction ceased.
Brunel did not live to see the bridge finished, although his colleagues and admirers at the Institution of Civil Engineers felt it would be a fitting memorial, and started to raise new funds and to amend the design. Work recommenced in 1862 and was completed in 1864, five years after Brunel’s death.
Brunel designed many bridges for his railway projects, including the Royal Albert Bridge spanning the River Tamar at Saltash near Plymouth, Somerset Bridge (an unusual laminated timber-framed bridge near Bridgwater), the Windsor Railway Bridge, and the Maidenhead Railway Bridge over the Thames in Berkshire. This last was the flattest, widest brick arch bridge in the world.
In 1845 Hungerford Bridge, a suspension footbridge across the Thames near Charing Cross Station in London, was opened. It was replaced by a new railway bridge in 1859, and the suspension chains were used to complete the Clifton Suspension Bridge.
Brunel designed the Royal Albert Bridge in 1855 for the Cornwall Railway, after Parliament rejected his original plan for a train ferry across the Hamoaze—the estuary of the tidal Tamar, Tavy and Lynher. The bridge (of bowstring girder or tied arch construction) consists of two main spans of 455 ft, 100 ft above mean high spring tide, plus 17 much shorter approach spans. Opened by Prince Albert on 2 May 1859, it was completed in the year of Brunel’s death.
In the early part of Brunel’s life, the use of railways began to take off as a major means of transport for goods. This influenced Brunel’s involvement in railway engineering, including railway bridge engineering.
In 1833, before the Thames Tunnel was complete, Brunel was appointed chief engineer of the Great Western Railway, one of the wonders of Victorian Britain, running from London to Bristol and later Exeter. The company was founded at a public meeting in Bristol in 1833, and was incorporated by Act of Parliament in 1835. It was Brunel’s vision that passengers would be able to purchase one ticket at London Paddington and travel from London to New York, changing from the Great Western Railway to the Great Western steamship at the terminus in Neyland, South Wales. He surveyed the entire length of the route between London and Bristol himself, with the help of many including his Solicitor Jeremiah Osborne of Bristol Law Firm Osborne Clarke who on one occasion rowed Isambard Kingdom Brunel down the River Avon himself to survey the bank of the river for the route.
Brunel made two controversial decisions: to use a broad gauge of 7 ft 1/4 in (2,140 mm) for the track, which he believed would offer superior running at high speeds; and to take a route that passed north of the Marlborough Downs—an area with no significant towns, though it offered potential connections to Oxford and Gloucester—and then to follow the Thames Valley into London. His decision to use broad gauge for the line was controversial in that almost all British railways to date had used standard gauge. Brunel said that this was nothing more than a carry-over from the mine railways that George Stephenson had worked on prior to making the world’s first passenger railway. Brunel proved through both calculation and a series of trials that his broader gauge was the optimum size for providing both higher speeds and a stable and comfortable ride to passengers. In addition the wider gauge allowed for larger carriages and thus greater freight capacity.
Drawing on Brunel’s experience with the Thames Tunnel, the Great Western contained a series of impressive achievements—soaring viaducts such as the one in Ivybridge, specially designed stations, and vast tunnels including the Box Tunnel, which was the longest railway tunnel in the world at that time.
The initial group of locomotives ordered by Brunel to his own specifications proved unsatisfactory, apart from the North Star locomotive, and 20-year-old Daniel Gooch was appointed as Superintendent of Locomotive Engines. Brunel and Gooch chose to locate their locomotive works at the village of Swindon, at the point where the gradual ascent from London turned into the steeper descent to the Avon valley at Bath.
Brunel’s achievements ignited the imagination of the technically minded Britons of the age, and he soon became quite notable in the country because of this interest.
After Brunel’s death the decision was taken that standard gauge should be used for all railways in the country.
The present London Paddington station was designed by Brunel and opened in 1854. Examples of his designs for smaller stations on the Great Western and associated lines which survive in good condition include Mortimer, Charlbury and Bridgend (all Italianate) and Culham (Tudorbethan). Surviving examples of wooden train sheds in his style are at Frome and Kingswear.
Overall, there were negative views as to how society viewed the railways. Some landowners felt the railways were a threat to amenities or property values and others requested tunnels on their land so the railway could not be seen.
In 1835, before the Great Western Railway had opened, Brunel proposed extending its transport network by boat from Bristol across the Atlantic Ocean to New York City. The Great Western Steamship Company was formed by Thomas Guppy for that purpose.
It was widely disputed whether it would be commercially viable for a ship powered purely by steam to make such long journeys. Technological developments in the early 1830s—including the invention of the surface condenser, which allowed boilers to run on salt water without stopping to be cleaned—made longer journeys more possible, but it was generally thought that a ship would not be able to carry enough fuel for the trip and have room for a commercial cargo.
Brunel formulated the theory that the amount a ship could carry increased as the cube of its dimensions, whereas the amount of resistance a ship experienced from the water as it travelled only increased by a square of its dimensions. This would mean that moving a larger ship would take proportionately less fuel than a smaller ship. To test this theory, Brunel offered his services for free to the Great Western Steamship Company, which appointed him to its building committee and entrusted him with designing its first ship, the Great Western.
When it was built, the Great Western was the longest ship in the world at 236 ft with a 250-foot keel. The ship was constructed mainly from wood, but Brunel added bolts and iron diagonal reinforcements to maintain the keel’s strength. In addition to its steam-powered paddle wheels, the ship carried four masts for sails. The Great Western embarked on her maiden voyage from Avonmouth, Bristol, to New York on 8 April 1838 with 600 long tons of coal, cargo and seven passengers on board.
Brunel himself missed this initial crossing, having been injured during a fire aboard the ship as she was returning from fitting out in London. As the fire delayed the launch several days, the Great Western missed its opportunity to claim title as the first ship to cross the Atlantic under steam power alone. Even with a four-day head start, the competing Sirius arrived only one day earlier and its crew was forced to burn cabin furniture, spare yards and one mast for fuel.
In contrast, the Great Western crossing of the Atlantic took 15 days and five hours, and the ship arrived at her destination with a third of its coal still remaining, demonstrating that Brunel’s calculations were correct. The Great Western had proved the viability of commercial transatlantic steamship service, which led the Great Western Steamboat Company to use her in regular service between Bristol and New York from 1838 to 1846. She made 64 crossings, and was the first ship to hold the Blue Riband with a crossing time of 13 days westbound and 12 days 6 hours eastbound. The service was commercially successful enough for a sister ship to be required, which Brunel was asked to design.
Brunel had become convinced of the superiority of propeller-driven ships over paddle wheels. After tests conducted aboard the propeller-driven steam tug Archimedes, he incorporated a large six-bladed propeller into his design for the 322-foot Great Britain, which was launched in 1843. Great Britain is considered the first modern ship, being built of metal rather than wood, powered by an engine rather than wind or oars, and driven by propeller rather than paddle wheel. She was the first iron-hulled, propeller-driven ship to cross the Atlantic Ocean. Her maiden voyage was made in August and September 1845, from Liverpool to New York. In 1846, she was run aground at Dundrum, County Down. She was salvaged and employed in the Australian service.
In 1852 Brunel turned to a third ship, larger than her predecessors, intended for voyages to India and Australia. The Great Eastern (originally dubbed Leviathan) was cutting-edge technology for her time: almost 700 ft long, fitted out with the most luxurious appointments, and capable of carrying over 4,000 passengers. Great Eastern was designed to cruise non-stop from London to Sydney and back (since engineers of the time misunderstood that Australia had no coal reserves), and she remained the largest ship built until the start of the 20th century.
Like many of Brunel’s ambitious projects, the ship soon ran over budget and behind schedule in the face of a series of technical problems. The ship has been portrayed as a white elephant, but in this case Brunel’s failure was principally one of economics—his ships were simply years ahead of their time. His vision and engineering innovations made the building of large-scale, propeller-driven, all-metal steamships a practical reality, but the prevailing economic and industrial conditions meant that it would be several decades before transoceanic steamship travel emerged as a viable industry.
Great Eastern was built at John Scott Russell’s Napier Yard in London, and after two trial trips in 1859, set forth on her maiden voyage from Southampton to New York on 17 June 1860. Though a failure at her original purpose of passenger travel, she eventually found a role as an oceanic telegraph cable-layer. The Great Eastern played a significant role in laying the first lasting transatlantic telegraph cable, which enabled telecommunication between Europe and North America.
During the Crimean War, an old Turkish barracks became the British Army Hospital in Scutari. Injured men contracted a variety of illnesses—including cholera, dysentery, typhoid and malaria—due to poor conditions there, and Florence Nightingale sent a plea to The Times for the government to produce a solution.
Brunel was working on the Great Eastern amongst other projects, but accepted the task in February 1855 of designing and building the War Office requirement of a temporary, pre-fabricated hospital that could be shipped to Crimea and erected there. In 5 months the team he had assembled designed, built, and shipped pre-fabricated wood and canvas buildings, providing them complete with advice on transportation and positioning of the facilities.
Brunel had been working Gloucester Docks-based William Eassrie on the launching stage for the Great Eastern, a man who had designed and built wooden prefabricated huts used in both the Australian gold rush, as well as by the British and French Armies in the Crimea. Using wood supplied by timber importers Price & Co., Eassrie fabricated 18 of the two-50 patient wards designed by Brunel, shipped directly via 16 ships from Gloucester Docks to the Dardanelles. The Renkioi Hospital was subsequently erected near Scutari Hospital, where Nightingale was based, in the malaria-free area of Renkioi.
His designs incorporated the necessities of hygiene: access to sanitation, ventilation, drainage, and even rudimentary temperature controls. They were feted as a great success, with some sources stating that of the approximately 1,300 patients treated in the hospital, there were only 50 deaths. In the Scutari hospital it replaced, deaths were said to be as many as 10 times this number. Nightingale referred to them as “those magnificent huts”. The practice of building hospitals from pre-fabricated modules survives today.
In 1830, he was elected a Fellow of the Royal Society.
On 5 July 1836, Brunel married Mary Elizabeth Horsley, who came from an accomplished musical and artistic family, being the eldest daughter of composer and organist William Horsley. They established a home at Duke Street, Westminster, in London.
In 1843, while performing a conjuring trick for the amusement of his children, Brunel accidentally inhaled a half-sovereign coin, which became lodged in his windpipe. A special pair of forceps failed to remove it, as did a machine devised by Brunel to shake it loose. At the suggestion of his father, Brunel was strapped to a board and turned upside-down, and the coin was jerked free. He recuperated at Teignmouth, and enjoyed the area so much that he purchased an estate at Watcombe in Torquay, Devon. Here he designed Brunel Manor and its gardens to be his retirement home. He never saw the house or gardens finished, as he died before it was completed.
Brunel, a heavy smoker, suffered a stroke in 1859, just before the Great Eastern made her first voyage to New York. He died ten days later at the age of 53 and was buried, like his father, in Kensal Green Cemetery in London. He left behind his wife Mary and three children: Isambard Brunel Junior, Henry Marc Brunel and Florence Mary Brunel. Henry Marc followed his father and grandfather in becoming a successful civil engineer.
