Isambard Kingdom Brunel

Isambard Kingdom Brunel was born on 9 April 1806 in Britain Street, Portsea, Portsmouth, Hampshire, where his father was working on block-making machinery. He was named Isambard after his father, the French civil engineer Sir Marc Isambard Brunel, and Kingdom after his English mother, Sophia Kingdom.

He had two elder sisters, Sophia, the eldest child, and Emma. The whole 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 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 Brunel 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-IV 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, who praised Brunel's potential in letters to his father. In late 1822, having completed his apprenticeship, Brunel returned to England.

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.

On 10 June 1830 Brunel was elected a Fellow of the Royal Society.

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.

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, West 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 Brunel down the River Avon himself to survey the bank of the river for the route.

Brunel had proposed extending its transport network by boat from Bristol across the Atlantic Ocean to New York City before the Great Western Railway opened in 1835. 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 applied the experimental evidence of Beaufoy and further developed 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.

Brunel married Mary Elizabeth Horsley (b. 1813) on 5 July 1836. She 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.

When it was built, the Great Western was the longest ship in the world at 236 ft (72 m) with a 250-foot (76 m) 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 (610,000 kg) 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 steamship Archimedes, he incorporated a large six-bladed propeller into his design for the 322-foot (98 m) 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. She is currently fully preserved and open to the public in Bristol, UK.

While performing a conjuring trick for the amusement of his children in 1843 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 commissioned William Burn to design Brunel Manor and its gardens to be his country home. He never saw the house or gardens finished as he died before it was completed.

Hungerford Bridge, a suspension footbridge across the Thames near Charing Cross Station in London, was opened in May 1845. Its central span was 676.5 feet (206.2 m), and its cost was £106,000. It was replaced by a new railway bridge in 1859, and the suspension chains were used to complete the Clifton Suspension Bridge.

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 (210 m) 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 mistakenly believed 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 it has been argued by David P. Billington that 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.

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.

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 (139 m), 100 ft (30 m) 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.

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 five 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's last major undertaking was the unique Three Bridges, London. Work began in 1856, and was completed in 1859.

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. Under Captain Sir James Anderson, the Great Eastern played a significant role in laying the first lasting transatlantic telegraph cable, which enabled telecommunication between Europe and North America.

Brunel, a heavy smoker, who had been diagnosed with Bright's disease (nephritis), suffered a stroke on 5 September 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, London. He is commemorated at Westminster Abbey in a window on the south side of the nave.

The words "I.K. BRUNEL ENGINEER 1859" were fixed to either end of the Royal Albert Bridge to commemorate his death in 1859, the year the bridge opened. The words were later partly obscured by maintenance access ladders but were revealed again by Network Rail in 2006 to honour his centenary.

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. In 2011, it was suggested, by historian and biographer Adrian Vaughan, that Brunel did not design the bridge, as eventually built, as the later changes to its design were substantial. His views reflected a sentiment stated fifty-two years earlier by Tom Rolt in his 1959 book Brunel. Re-engineering of suspension chains recovered from an earlier suspension bridge was one of many reasons given why Brunel's design could not be followed exactly.

In 1865, the East London Railway Company purchased the Thames Tunnel for £200,000, and four years later the first trains passed through it. Subsequently, the tunnel became part of the London Underground system, and remains in use today, originally as part of the East London Line now incorporated into the London Overground.

Brunel was the subject of Great, a 1975 animated film directed by Bob Godfrey. It won the Academy Award for Animated Short Film at the 48th Academy Awards in March 1976.

A public poll conducted by the BBC in 2001 to select the 100 Greatest Britons, Brunel was placed second, behind Winston Churchill. Brunel's life and works have been depicted in numerous books, films and television programs. The 2003 book and BBC TV series Seven Wonders of the Industrial World included a dramatisation of the building of the Great Eastern.

The Royal Mint struck two £2 coins in 2006 to "celebrate the 200th anniversary of Isambard Kingdom Brunel and his achievements". The first depicts Brunel with a section of the Royal Albert Bridge and the second shows the roof of Paddington Station. In the same year the Post Office issued a set of six wide commemorative stamps (SG 2607-12) showing the Royal Albert Bridge, the Box Tunnel, Paddington Station, the Great Eastern, the Clifton Suspension Bridge, and the Maidenhead Bridge.

A celebrated engineer in his era, Brunel remains revered today, as evidenced by numerous monuments to him. There are statues in London at Temple (pictured), Brunel University and Paddington station, and in Bristol, Plymouth, Swindon, Milford Haven and Saltash. A statue in Neyland in Pembrokeshire in Wales was stolen in August 2010. The topmast of the Great Eastern is used as a flagpole at the entrance to Anfield, Liverpool Football Club's ground. Contemporary locations bear Brunel's name, such as Brunel University in London, shopping centres in Swindon and also Bletchley, Milton Keynes, and a collection of streets in Exeter: Isambard Terrace, Kingdom Mews, and Brunel Close. A road, car park, and school in his home city of Portsmouth are also named in his honour, along with one of the city's largest public houses. There is an engineering lab building at the University of Plymouth named in his honour.

At the 2012 Summer Olympics opening ceremony, Brunel was portrayed by Kenneth Branagh in a segment showing the Industrial Revolution.

In 2017, inventor Max Schlienger unveiled a working model of an updated atmospheric railroad at his vineyard in the Northern California town of Ukiah.
