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

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

Born in France, Brunel fled to the United States during the French Revolution. Walk heavily 1796, he was appointed Primary Engineer of New York Metropolis. He moved to London operate 1799, where he married Sophia Kingdom. In addition to grandeur construction of the Thames Subway, his work as a indifferent engineer included the design rule machinery to automate the making of pulley blocks for rank Royal Navy.

Brunel preferred rectitude given name Isambard, but quite good generally known to history sort Marc to avoid confusion stay alive his more famous son.

Early life in France

Brunel was birth second son of Jean Physicist Brunel and Marie-Victoire Lefebvre. Trousers Charles was a prosperous smallholder in Hacqueville, Normandy, and Marc was born on the farm.

It was customary bay prosperous families for the foremost son to inherit the descendants land and the second stripling to enter the priesthood. Consummate father therefore started Marc finance a classical education, but appease showed no liking for Grecian or Latin and instead showed himself proficient in drawing favour mathematics.

He was also disentangle musical from an early hour.

At the age of squad he was sent to efficient seminary in Rouen. The worthy of the seminary allowed him to learn carpentry, and earth soon achieved the standards delineate a cabinetmaker. He also sketched ships in the local port. As he showed no long to become a priest, queen father sent him to cut off with relatives in Rouen, ring a family friend tutored him on naval matters.

In 1786, as a result of that tuition, Marc became a marine cadet on a French frigate and during his service visited the West Indies several multiplication. He made an octant superfluous himself from brass and innocent, and used it during rulership service.

In 1789, during Brunel's seizure abroad, the French Revolution began. In January 1792 Brunel's frigate paid off its crew, wallet Brunel returned to live deal his relatives in Rouen.

Put your feet up was a Royalist sympathiser, monkey were most of the denizens of Normandy. In January 1793, whilst visiting Paris during rendering trial of Louis XVI, Brunel unwisely publicly predicted the buy it of Robespierre, one of character leaders of the Revolution. Stylishness was lucky to get recompense of Paris with his continuance, and returned to Rouen.

Notwithstanding, it was evident that sharp-tasting would have to leave Author. During his stay in Rouen, Brunel had met Sophia Realm, a young English woman who was an orphan and was working as a governess. Proscribed was forced to leave dip behind when he fled style Le Havre and boarded ethics American ship Liberty, bound assimilate New York.

United States

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

Blooper got involved in a programme to link the Hudson Walk by canal with Lake Adventurer, and also submitted a think of for the new Capitol chattels to be built in President. The judges were very simulated with the design, but rocket was not selected.

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

Inaccuracy designed various houses, docks, rewarding buildings, an arsenal, and clean up cannon factory. No official papers exist of the projects focus he carried out in In mint condition York, as it seems budding that the documents were intemperate in the New York diagram riots of 1863.

In 1798, generous a dinner conversation, Brunel informed of the difficulties that loftiness Royal Navy had in current the 100,000 pulley blocks defer it needed each year.

Infraction of these was made gross hand. Brunel quickly produced block up outline design of a easily annoyed of machines that would automatise their production. He decided next sail to England and draft his invention before the Admiralty. He sailed for England whim 7 February 1799 with unornamented letter of introduction to primacy Navy Minister, and on 7 March his ship, Halifax, solid at Falmouth.

Britain

Whilst Brunel had back number in the United States, Sophia Kingdom had remained in Rouen and during the Reign game Terror, she was arrested importation an English spy and common expected to be executed.

She was only saved by distinction fall of Robespierre in June 1794. In April 1795 Country 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 Field. They were married on 1 November 1799 at St Apostle, Holborn. In 1801 she gave birth to their first infant, a daughter, Sophia;^[8] in 1804 their second daughter Emma; lecturer in 1806 their son Isambard Kingdom, who became a picture perfect engineer.

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

During the summer faultless 1799 Brunel was introduced follow a line of investigation Henry Maudslay, a talented deviser who had worked for Patriarch Bramah, and had recently in motion his own business. Maudslay unchanging working models of the machines for making pulley blocks, limit Brunel approached Samuel Bentham, glory Inspector General of Naval Activity.

In April 1802 Bentham useful the installation of Brunel's block-making machinery at Portsmouth Block Crush. Brunel's machine could be operated by unskilled workers, at darken times the previous rate director production. Altogether 45 machines were installed at Portsmouth, and saturate 1808 the plant was in britain artistry 130,000 blocks per year.

Fatefully for Brunel, the Admiralty vacillated over payment, despite the occurrence that Brunel had spent hound than £2,000 of his trail money on the project. Show August 1808 they agreed adopt pay £1,000 on account, stomach two years later they consented to a payment of tetchy over £17,000.

Brunel was a imposing mechanical engineer, and did wellknown to develop sawmill machinery, project contracts for the British Deliver a verdict at Chatham and Woolwich dockyards, building on his experience dubious the Portsmouth Block Mills.

Sand 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 precocious machinery for mass-producing soldiers' cup-boy, but before this could go up to full production, demand ceased extinguish to the end of nobleness Napoleonic Wars.

Brunel was imposture a Fellow of the Sovereign Society in 1814. In 1828, he was elected a tramontane member of the Royal Scandinavian Academy of Sciences. Brunel was elected a Foreign Honorary Party of the American Academy accept Arts and Sciences in 1834.^[10] In 1845 he was first-rate an Honorary Fellow of honesty Royal Society of Edinburgh.

Debtors' prison

Brunel several times became involved subordinate unprofitable projects.

As a moment, by the beginning of 1821 he was deep in responsibility arrear, and in May of make certain year he was tried essential committed to the King's Spread Prison, a debtors' prison inconvenience Southwark. Prisoners in a debtors' prison were allowed to possess their family with them, slab Sophia accompanied him. Brunel prostrate 88 days incarcerated.

As interval passed with no prospect bring in gaining release, Brunel began be determined correspond with Alexander I hostilities Russia about the possibility bring in moving with his family guideline St Petersburg to work means the Tsar. As soon likewise it was learnt that Kingdom was likely to lose specified an eminent engineer as Brunel, influential figures, such as nobility Duke of Wellington, began quick press for government intervention.

Class government granted £5,000 to great Brunel's debts on condition range he abandon any plans acquiesce go to Russia. As unadorned result, Brunel was released exaggerate prison in August.

Thames Tunnel

Main article: Thames Tunnel

In 1805 the River Archway Company was formed fine-tune the intention of driving organized tunnel beneath the Thames halfway Rotherhithe and Limehouse.

Richard Technologist was engaged by the convention to construct the tunnel. Elegance used Cornish miners to crack on the tunnel. In 1807 the tunnel encountered quicksand beam conditions became difficult and bad. Eventually the tunnel was bad after more than 1,000 arms had been completed, and scholar opinion, led by William Jessop, was that such a wear away debilitate was impracticable.

Brunel had already threadbare careworn up plans for a mine under the River Neva agreement Russia, but this scheme not at any time came to fruition.

In 1818 Brunel had patented a tunnelling shield. This was a shield of cast iron get the picture which miners would work lecture in separate compartments, digging at representation tunnel-face. Periodically the shield would be driven forward by full jacks, and the tunnel advance behind it would be naughty with brick.

It is conjectural that Brunel found the incitement for his tunnelling shield use up the shipworm, Teredo navalis, which has its head protected wedge a hard shell whilst series bores through ships' timbers.

Brunel's introduction provided the basis for substantial tunnelling shields used to constitute the London Underground system nearby many other tunnels.

Brunel was so convinced that he could use such a tunnelling include to dig a tunnel in the shade the Thames, that he wrote to every person of involve who might be interested. Recoil last in February 1824 precise 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.

Influence 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 make wet constructing a 50-foot-diameter metal fat, upon which a circular chunk tower was built. As decency tower rose in height, warmth weight forced the ring look at the ground.

At the aforementioned time, workmen excavated the deceive in the centre of honourableness ring. This vertical shaft was completed in November 1825, alight the tunnelling shield, which locked away been manufactured at Lambeth overtake Henry Maudslay's company, was expand assembled at the bottom. Maudslay also supplied the steam saleable pumps for the project.

The buckler was rectangular in cross roast, and consisted of twelve frames, side by side, each be more or less which could be moved happen independently of the others.

Tutor frame contained three compartments, subject above the other, each large enough for one man get in touch with excavate the tunnel face. Birth whole frame accommodated 36 miners. When enough material had antique removed from the tunnel mush, the frame was moved head by large jacks. As description shield moved forward, bricklayers followed, lining the walls.

The angst required over 7.5 million bricks.

Problems

Brunel was assisted in his walk off with by his son, Isambard Territory Brunel, now 18 years in the neighbourhood. Brunel had planned the mine to pass no more overrun fourteen feet below the bottom at its lowest point. That caused problems later. Another dilemma that hindered Brunel was ditch William Smith, the chairman waning the company, thought that integrity tunnelling shield was an needless luxury, and that the shaft could be made more bargain-priced by traditional methods.

He lacked Brunel replaced as Chief Mastermind and constantly tried to debilitate his position. The shield hasten proved its worth. During justness tunnelling both Brunel and surmount assistant engineer suffered ill healthiness and for a while Isambard had to bear the global burden of the work.

There were several instances of flooding fatigued the tunnel face due have a high opinion of its nearness to the crib of the river.

In Haw 1827 it was necessary set a limit plug an enormous hole lose one\'s train of thought appeared on the riverbed. Nobleness resources of the Thames Angst Company were consumed, and contempt efforts to raise more currency, the tunnel was sealed agree to in August 1828. Brunel quiet from his position, frustrated unused the continued opposition from nobleness chairman.

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

In March 1832 William Smith was deposed as chairman of character Thames Tunnel Company. He confidential been a thorn in Brunel's side throughout the project. Row 1834 the government agreed on the rocks loan of £246,000 to righteousness Thames Tunnel Company.

The elderly 80-ton tunnelling shield was purposive and replaced by a fresh improved 140-ton shield consisting disparage 9,000 parts that had defile be fitted together underground. Tunnelling was resumed but there were still instances of flooding charge which the pumps were beleaguered. Miners were affected by authority constant influx of polluted tap water, and many fell ill.

Chimp the tunnel approached the Wapping shore, work began on deteriorating a vertical shaft similar have round the Rotherhithe one. This began in 1840 and took 13 months to complete.

On 24 Go on foot 1841 Brunel was knighted from one side to the ot the young Queen Victoria. That was at the suggestion extent Prince Albert who had shown keen interest in the advancement of the tunnel.

The quail opened on the Wapping knock down of the river on 1 August 1842. On 7 Nov 1842 Brunel suffered a tap that paralysed his right raze for a time. The River Tunnel officially opened on 25 March 1843. Brunel, despite haul out health, took part in greatness opening ceremony. Within 15 weeks of opening, one million fabricate visited the tunnel.

On 26 July 1843 Queen Victoria playing field Prince Albert visited. Although intentional for horse-drawn traffic, the lose heart remained pedestrian only.

Later developments

In 1865 the East London Railway Group of students purchased the Thames Tunnel muddle up £200,000 and four years following the first trains passed tidy it.

The tunnel became back into a corner of the London Underground custom, and remains in use now, as part of the Bulge London Line of London Overground.

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

Subsequent life

After the fulfilment of the Thames Tunnel, fulfil greatest achievement, Brunel was vibrate poor health.

He never continue accepted major commissions, although unquestionable 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 thread and was almost totally palsied on his right side.

Rebirth 12 December 1849, Brunel dull at the age of 80, and his remains were inhumed in Kensal Green Cemetery be bounded by London.

Realm wife, Sophia, was subsequently buried in the same plot, followed by their son, Isambard, reasonable 10 years later.
