ISAMBARD See also:

KINGDOM See also:BRUNEL (1806-1859)  , rnglish engineer, only son of See also:Sir M . I . See also:Brunel, was See also:born at See also:Portsmouth on the 9th of See also:April 18o6 . He displayed in childhood singular See also:powers of See also:mental calculation, See also:great skill and rapidity as a draughtsman, and a true feeling for See also:art . At the See also:age of fourteen he was sent to See also:Paris, to study at the See also:College See also:Henri Quatre . In 1823 he entered his See also:father's See also:office as assistant-engineer, just at the See also:time when the project of the See also:Thames See also:Tunnel was beginning to take shape; and during the later portion of the time, from 1825, when the See also:work was begun, till 1828, when it was stopped by an irruption of the See also:river, he was both nominal and actual See also:resident engineer . In See also:November 1829 he sent in designs and plans for the projected suspension See also:bridge over the See also:Avon at See also:Clifton, but in consequence of objections raised by See also:Thomas See also:Telford, the See also:referee of the bridge See also:committee, his plans were rejected . But a new See also:design which he sent in on a second competition in 1831 was accepted, and he was appointed engineer . The See also:works were begun in 1836, but owing to lack of funds were not completed until 1864, after Brunel's See also:death; his design, however, was closely adhered to, and the chains employed came from the old See also:Hungerford suspension bridge (See also:London), which he had built in 1841-1845, but which was displaced in 1862 by the Charing See also:Cross railway bridge . In See also:March 1833 Brunel, at the age of twenty-seven, was appointed engineer of the newly-projected Great Western railway . For several years his energies were taxed to the utmost by the conflict with obstructive landowners and See also:short-sighted critics; but he showed himself equal to the occasion, not only as a professional See also:man, but as a persuasive negotiator . Among the See also:engineering triumphs on that railway are the See also:Hanwell viaduct, the See also:Maidenhead bridge and the See also:Box tunnel, at the time the longest in the See also:world .

The famous " See also:

battle of-the gauges " took its rise from his introduction of the broad (7 ft.)*See also:gauge on that See also:line . In 1846 he resigned his office as engineer of the Great Western railway . In 1844 he had recommended the See also:adoption of the atmospheric See also:system on the See also:South See also:Devon railway, but after a See also:year's trial the system was abandoned . The last and greatest of Brunel's railway works was the Royal See also:Albert bridge over the river Tamar at See also:Saltash . This work, sanctioned by See also:parliament in 1845, was constructed between 1853 and 1859 . In addition to the arduous labours of railway engineering Brunel took a leading See also:part in the systematic development of ocean See also:steam See also:navigation . As See also:early as See also:October 1835 he had suggested to the See also:directors of the Great Western railway, that they should " make it longer, and have a steamboat to go from See also:Bristol to New See also:York, and See also:call it the ` Great Western.' " The project was taken up, and the " Great Western " steamship was designed by Brunel, and built at Bristol under his superintendence . It was much longer than any steamer of the See also:day, and was the first steamship built to make See also:regular voyages across the See also:Atlantic . While the See also:vessel was See also:building a controversy was raised about the practicability of Brunel's See also:scheme, Dr D . See also:Lardner asserting dogmatically that the voyage could not be made, and backing his assertion with an See also:array of figures . His view was widely accepted, but the work went on, and the voyage was accomplished in 1838 . Brunel at once undertook a still larger design in the " Great See also:Britain," which was the first large See also:iron steamship, the largest See also:ship afloat at that time, and the first large ship in which the See also:screw-propeller was used .

She made her first voyage from See also:

Liverpool to New York in See also:August and See also:September 1845; but in the following year was carelessly runupon the rocks in Dundrum See also:Bay on the See also:coast of See also:Ireland . After lying there nearly a year without material damage she was got off and was employed in the Australian See also:trade . Brunel soon after began to meditate a still vaster project, the construction of a vessel large enough to carry all the See also:coal required for a See also:long voyage out, and if coal could not be had at the out See also:port, then to carry enough also for the return voyage . It seemed to h'm, further, that a great increase of See also:size would give many advantages for navigation . During his connexion as engineer with the Australian See also:Mail See also:Company he worked out into a See also:practical shape his conception of a " great ship "; and in 1852 his scheme was laid before the directors of the Eastern Steam Navigation Company . It was adopted, the projector being appointed engineer, and after much time occupied about contracts and specifications the work was begun in See also:December 1853 . Immense difficulties in the progress of construction caused delays from time to time . The operation of launching was several times attempted in vain; but at length the gigantic vessel, the " Great Eastern," was got afloat on the 31st of See also:January 1858 . Much remained to be done to See also:complete the ship; and her engineer, overworked and worn out with worry, See also:broke down and did not sec her begin her first voyage on the 7th of September 1859 . On the 5th he was brought See also:home from the ship suffering from a paralytic stroke, and on the 15th he died at his See also:house in See also:Westminster . In addition to the great works already described, Brunel was employed in the construction of many docks and piers, as at Monkwearmouth, Bristol, See also:Plymouth, Briton See also:Ferry, See also:Brentford and See also:Milford Haven . He was a zealous See also:promoter of the Great See also:Exhibition of 1851, and was a member of the committee on the See also:section of machinery and of the building committee .

He paid much See also:

attention to the improvement of large guns, and designed a floating See also:gun-See also:carriage for the attack on See also:Kronstadt in the See also:Russian See also:War (1854); he also designed and superintended the construe tion of the See also:hospital buildings at Erenkeni on the See also:Dardanelles (1855) . He was elected a See also:fellow of the Royal Society in 1830, and in 1858 declined the See also:presidency of the Institution of See also:Civil See also:Engineers through See also:ill-See also:health . He received the degree of D.C.L. from See also:Oxford in 1857 . In his work he was singularly See also:free from professional See also:jealousy, and was always ready to commend and help others, though, himself a man of remarkable See also:industry and See also:energy, he demanded a high See also:standard of faithful service from his subordinates .
