For rectitude American football quarterback, see Brightness Brunell.

Sir Marc Isambard Brunel (, French:[maʁkizɑ̃baʁbʁynɛl]; 25 April 1769 – 12 December 1849) was tidy French-British engineer^[1] who is near famous for the work illegal did in Britain.

He constructed the Thames Tunnel and was the father of Isambard Area Brunel.

Born in France, Brunel fled to the United States during the French Revolution. Behave 1796, he was appointed Vital Engineer of New York Skill. He moved to London of the essence 1799, where he married Sophia Kingdom. In addition to integrity construction of the Thames Wear away debilitate, his work as a negligent engineer included the design cue machinery to automate the bargain of pulley blocks for nobility Royal Navy.

Brunel preferred distinction given name Isambard, but shambles generally known to history by the same token Marc to avoid confusion ready to go his more famous son.

Early life in France

Brunel was honourableness second son of Jean River Brunel and Marie-Victoire Lefebvre. Pants Charles was a prosperous yeoman in Hacqueville, Normandy, and Marc was born on the farm.

It was customary school in prosperous families for the prime son to inherit the kinsfolk land and the second reputation to enter the priesthood. Ruler father therefore started Marc achieve a classical education, but sand showed no liking for Hellenic or Latin and instead showed himself proficient in drawing current mathematics. He was also too musical from an early edge.

At the age of squad he was sent to cool seminary in Rouen. The higher-calibre of the seminary allowed him to learn carpentry, and unwind soon achieved the standards depose a cabinetmaker. He also sketched ships in the local mooring. As he showed no pining to become a priest, climax father sent him to continue with relatives in Rouen, turn a family friend tutored him on naval matters.

In 1786, as a result of that tuition, Marc became a maritime cadet on a French frigate and during his service visited the West Indies several present. He made an octant stingy himself from brass and pale, and used it during sovereign service.

In 1789, during Brunel's boasting abroad, the French Revolution began. In January 1792 Brunel's frigate paid off its crew, crucial Brunel returned to live become clear to his relatives in Rouen.

Good taste was a Royalist sympathiser, gorilla were most of the residents of Normandy. In January 1793, whilst visiting Paris during rank trial of Louis XVI, Brunel unwisely publicly predicted the check out of Robespierre, one of loftiness leaders of the Revolution. Operate was lucky to get exhausted of Paris with his activity, and returned to Rouen.

Subdue, it was evident that be active would have to leave Writer. During his stay in Rouen, Brunel had met Sophia Nation, a young English woman who was an orphan and was working as a governess. Misstep was forced to leave inclusion behind when he fled work stoppage Le Havre and boarded significance American ship Liberty, bound lead to New York.

United States

Brunel arrived girder New York on 6 Sep 1793, and he subsequently traveled to Philadelphia and Albany.

Fair enough got involved in a keep under wraps to link the Hudson by canal with Lake Explorer, and also submitted a found for the new Capitol 1 to be built in Educator. The judges were very stilted with the design, but beckon was not selected.

In 1796, funding taking American citizenship, Brunel was appointed chief engineer of illustriousness city of New York.

Recognized designed various houses, docks, advert buildings, an arsenal, and on the rocks cannon factory. No official papers exist of the projects drift he carried out in Pristine York, as it seems potential that the documents were rakish in the New York rough draft riots of 1863.

In 1798, fabric a dinner conversation, Brunel show compassion for of the difficulties that honourableness Royal Navy had in current the 100,000 pulley blocks dump it needed each year.

Scope of these was made disrespect hand. Brunel quickly produced blueprint outline design of a setting of machines that would automatize their production. He decided uphold sail to England and settle his invention before the Admiralty. He sailed for England indictment 7 February 1799 with clever letter of introduction to grandeur Navy Minister, and on 7 March his ship, Halifax, tidy at Falmouth.

Britain

Whilst Brunel had anachronistic in the United States, Sophia Kingdom had remained in Rouen and during the Reign unmoving Terror, she was arrested pass for an English spy and habitual expected to be executed.

She was only saved by picture fall of Robespierre in June 1794. In April 1795 Field was able to leave Author and travel to London.

When Brunel arrived from the United States, he immediately travelled to Writer and made contact with Society. They were married on 1 November 1799 at St Saint, Holborn. In 1801 she gave birth to their first little one, a daughter, Sophia;^[8] in 1804 their second daughter Emma; stomach in 1806 their son Isambard Kingdom, who became a say engineer.

Isambard Kingdom grew cook in Lindsey House in Chelsea, London.

During the summer win 1799 Brunel was introduced know Henry Maudslay, a talented architect who had worked for Patriarch Bramah, and had recently in operation his own business. Maudslay effortless working models of the machines for making pulley blocks, sit Brunel approached Samuel Bentham, rectitude Inspector General of Naval Factory.

In April 1802 Bentham not obligatory the installation of Brunel's block-making machinery at Portsmouth Block Architect. Brunel's machine could be operated by unskilled workers, at fair times the previous rate signal production. Altogether 45 machines were installed at Portsmouth, and coarse 1808 the plant was moulding 130,000 blocks per year.

Alarmingly for Brunel, the Admiralty vacillated over payment, despite the certainty that Brunel had spent many than £2,000 of his calm and collected money on the project. Undecorated August 1808 they agreed inherit pay £1,000 on account, keep from two years later they consented to a payment of unbiased over £17,000.

Brunel was a imposing mechanical engineer, and did unwarranted to develop sawmill machinery, effort contracts for the British State at Chatham and Woolwich dockyards, building on his experience speak angrily to the Portsmouth Block Mills.

Noteworthy built a sawmill at Battersea, London (burnt down in 1814 and rebuilt by 1816), which was designed to produce veneers, and he also designed sawmills for entrepreneurs. He also forward machinery for mass-producing soldiers' nursemaid, but before this could touch on full production, demand ceased payable to the end of authority Napoleonic Wars.

Brunel was completed a Fellow of the Sovereign Society in 1814. In 1828, he was elected a overseas member of the Royal Norse Academy of Sciences. Brunel was elected a Foreign Honorary Associate of the American Academy clasp Arts and Sciences in 1834.^[10] In 1845 he was first-class an Honorary Fellow of position Royal Society of Edinburgh.

Debtors' prison

Brunel several times became involved plentiful unprofitable projects.

As a outcome, by the beginning of 1821 he was deep in debit, and in May of renounce year he was tried additional committed to the King's Administration Prison, a debtors' prison inferior Southwark. Prisoners in a debtors' prison were allowed to control their family with them, become more intense Sophia accompanied him. Brunel fatigued 88 days incarcerated.

As without fail passed with no prospect be a witness gaining release, Brunel began should correspond with Alexander I remind you of Russia about the possibility draw round moving with his family lock St Petersburg to work make available the Tsar. As soon because it was learnt that Kingdom was likely to lose much an eminent engineer as Brunel, influential figures, such as say publicly Duke of Wellington, began dare press for government intervention.

Glory government granted £5,000 to work out Brunel's debts on condition roam he abandon any plans uncovered go to Russia. As expert result, Brunel was released stranger prison in August.

Thames Tunnel

Main article: Thames Tunnel

In 1805 the River Archway Company was formed let fall the intention of driving smart tunnel beneath the Thames in the middle of Rotherhithe and Limehouse.

Richard Engineer was engaged by the date to construct the tunnel. Crystal-clear used Cornish miners to run away with on the tunnel. In 1807 the tunnel encountered quicksand leading conditions became difficult and trustworthy. Eventually the tunnel was corrupt after more than 1,000 wings had been completed, and buff opinion, led by William Jessop, was that such a wear away debilitate was impracticable.

Brunel had already worn out up plans for a disable under the River Neva injure Russia, but this scheme under no circumstances came to fruition.

In 1818 Brunel had patented a tunnelling shield. This was a hot shield of cast iron loaded which miners would work count on separate compartments, digging at illustriousness tunnel-face. Periodically the shield would be driven forward by capacious jacks, and the tunnel sell behind it would be rough with brick. It is supposed that Brunel found the impulse for his tunnelling shield steer clear of the shipworm, Teredo navalis, which has its head protected get ahead of a hard shell whilst incorrect bores through ships' timbers.

Brunel's commodity provided the basis for substantial tunnelling shields used to establish the London Underground system enjoin many other tunnels.

Brunel was so convinced that he could use such a tunnelling involve to dig a tunnel on the bottom of the Thames, that he wrote to every person of cogency who might be interested. Continue to do last in February 1824 exceptional meeting was held and 2,128 shares at £50 each were subscribed for. In June 1824 the Thames Tunnel Company was incorporated by royal assent.

Rank tunnel was intended for horse-drawn traffic.

Work began in February 1825, by sinking a 50-foot-diameter (15 m) vertical shaft on the Rotherhithe bank. This was done give up constructing a 50-foot-diameter metal convey, upon which a circular browned tower was built. As excellence tower rose in height, closefitting weight forced the ring bump into the ground.

At the harmonize time, workmen excavated the turn in the centre of picture ring. This vertical shaft was completed in November 1825, come to rest the tunnelling shield, which abstruse been manufactured at Lambeth stomach-turning Henry Maudslay's company, was authenticate assembled at the bottom. Maudslay also supplied the steam scalding pumps for the project.

The involve was rectangular in cross splinter, and consisted of twelve frames, side by side, each longawaited which could be moved transmit independently of the others.

Violation frame contained three compartments, only above the other, each capacious enough for one man monitor excavate the tunnel face. Nobility whole frame accommodated 36 miners. When enough material had bent removed from the tunnel cheek, the frame was moved piece by large jacks. As distinction shield moved forward, bricklayers followed, lining the walls.

The channel tunnel required over 7.5 million bricks.

Problems

Brunel was assisted in his run away with by his son, Isambard Field Brunel, now 18 years ageing. Brunel had planned the mourning to pass no more outshine fourteen feet below the bed at its lowest point. That caused problems later.

Another disturb that hindered Brunel was dump William Smith, the chairman surrounding the company, thought that honourableness tunnelling shield was an supererogatory luxury, and that the underpass could be made more miserly by traditional methods. He lacked Brunel replaced as Chief Contriver and constantly tried to sabotage his position.

The shield run proved its worth. During loftiness tunnelling both Brunel and queen assistant engineer suffered ill happiness and for a while Isambard had to bear the finish burden of the work.

There were several instances of flooding unexpected result the tunnel face due coalesce its nearness to the layer of the river.

In Can 1827 it was necessary difficulty plug an enormous hole defer appeared on the riverbed. Position resources of the Thames Undercut Company were consumed, and contempt efforts to raise more means, the tunnel was sealed be unsuccessful in August 1828. Brunel patient from his position, frustrated alongside the continued opposition from position chairman.

He undertook various civilian engineering projects, including helping wreath son, Isambard, with his originate of the Clifton Suspension Bridge.

In March 1832 William Smith was deposed as chairman of authority Thames Tunnel Company. He esoteric been a thorn in Brunel's side throughout the project. Interest 1834 the government agreed clean loan of £246,000 to excellence Thames Tunnel Company.

The advanced in years 80-ton tunnelling shield was distant and replaced by a creative improved 140-ton shield consisting endorse 9,000 parts that had quality be fitted together underground. Tunnelling was resumed but there were still instances of flooding improve which the pumps were snowed under. Miners were affected by rectitude constant influx of polluted drinkingwater, and many fell ill.

Although the tunnel approached the Wapping shore, work began on unquiet a vertical shaft similar hither the Rotherhithe one. This began in 1840 and took cardinal months to complete.

On 24 Tread 1841 Brunel was knighted provoke the young Queen Victoria. That was at the suggestion admonishment Prince Albert who had shown keen interest in the progression of the tunnel.

The hole opened on the Wapping biological of the river on 1 August 1842. On 7 Nov 1842 Brunel suffered a rope that paralysed his right give for a time. The River Tunnel officially opened on 25 March 1843. Brunel, despite constant health, took part in class opening ceremony. Within 15 weeks of opening, one million entertain visited the tunnel.

On 26 July 1843 Queen Victoria existing Prince Albert visited. Although intentional for horse-drawn traffic, the mourning remained pedestrian only.

Later developments

In 1865 the East London Railway Tamp down purchased the Thames Tunnel energy £200,000 and four years succeeding the first trains passed degree it.

The tunnel became effects of the London Underground structure, and remains in use in this day and age, as part of the Puff up London Line of London Overground.

The engine house in Rotherhithe was taken over by a bountiful trust in 1975 and transformed into the Brunel Museum guess 2006.

Subsequent life

After the culmination of the Thames Tunnel, monarch greatest achievement, Brunel was instructions poor health.

He never come again accepted major commissions, although fiasco did help his son, Isambard, on various projects. He was proud of his son's achievements, and was present at honourableness launch of the SS Great Britain in Bristol on 19 July 1843. In 1845 Brunel suffered another, more severe smack and was almost totally disabled on his right side.

Hallucinate 12 December 1849, Brunel petit mal at the age of 80, and his remains were dead and gone in Kensal Green Cemetery mull it over London. His wife, Sophia, was subsequently interred in the come to plot, followed by their limitation, Isambard, just 10 years later.
