SIR See also:JOHN See also:HAWKSHAW (1811-1891)  , See also:English engineer, was See also:born in See also:Yorkshire in 1811, and was educated at See also:Leeds See also:grammar school . Before he was twenty-one he had been engaged for six or seven years in railway See also:engineering and the construction of roads in his native See also:county, and in the See also:year of his See also:majority he obtained an See also:appointment as engineer to the See also:Bolivar See also:Mining Association in See also:Venezuela . But the See also:climate there was more than his See also:health could stand, and in 1834 he was obliged to return to See also:England . He soon obtained employment under See also:Jesse See also:Hartley at the See also:Liverpool docks, and subsequently was made engineer in See also:charge of the railway and See also:navigation See also:works of the See also:Manchester, See also:Bury and See also:Bolton See also:Canal See also:Company . In 1845 he became See also:chief engineer to the Manchester & Leeds railway, and in 1847 to its successor, the See also:Lancashire & Yorkshire railway, for which he constructed a large number of See also:branch lines . In 185o he removed to See also:London and began to practise as a consulting engineer, at first alone, but subsequently in See also:partnership with See also:Harrison See also:Hayter . In that capacity his See also:work was of an extremely varied nature, embracing almost every branch of engineering . He retained his connexion with the Lancashire & Yorkshire Company until his retirement from professional work in 1888, and was consulted on all the important engineering points that affected it in that See also:long See also:period . In London he was responsible for the Charing See also:Cross and See also:Cannon See also:Street See also:railways, together with the two See also:bridges which carried them over the See also:Thames; he was engineer of the See also:East London railway, which passes under the Thames through See also:Sir M . I . See also:Brunel's well-known See also:tunnel; and jointly with Sir J . See also:Wolfe See also:Barry he constructed the See also:section of the Underground railway which completed the " inner circle " between the Aldgate and See also:Mansion See also:House stations .

In addition, many railway works claimed his See also:

attention in all parts of the See also:worldSee also:Germany, See also:Russia, See also:India, See also:Mauritius, &c . One noteworthy point in his railway practice was his advocacy, in opposition to See also:Robert See also:Stephenson, of steeper gradients than had previously been thought desirable or possible, and so far back as 1838 he expressed decided disapproval of the See also:maintenance of the broad See also:gauge on the See also:Great Western, because of the troubles he foresaw it would See also:lead to in connexion with future railway See also:extension, and because he objected in See also:general to breaks of gauge in the lines of a See also:country . The construction of canals was another branch of engineering in which he was actively engaged . In 1862 he became engineer of the See also:Amsterdam See also:ship-canal, and in the succeeding year he may fairly be said to have been the saviour of the See also:Suez Canal . About that See also:time the See also:scheme was in very See also:bad odour, and the See also:khedive determined to get the See also:opinion of an English engineer as to its practicability, having made up his mind to stop the works if that opinion was unfavourable . See also:Hawkshaw was chosen to make the inquiry, and it was because his See also:report was entirely favourable that M. de See also:Lesseps was able to say at the opening ceremony that.to him he owed the canal . As a member of the See also:International See also:Congress which considered the construction of an interoceanic canal across central See also:America, he thought best of the Nicaraguan route, and privately he regarded the See also:Panama scheme as impracticable at a reasonable cost, although publicly he expressed no opinion on the See also:matter and See also:left the Congress without voting . Sir See also:John Hawkshaw also had a wide experience in constructing harbours (e.g . See also:Holyhead) and docks (e.g . See also:Penarth, the See also:Albert See also:Dock at See also:Hull, and the See also:south dock of the East and See also:West India Docks in London), in See also:river-engineering, in drainage and See also:sewerage, in See also:water-See also:supply, &c . He was engineer, with Sir See also:James Brunlees, of the See also:original Channel Tunnel Company from 1872, but many years previously he had investigated for himsself the question of a tunnel under the Strait of See also:Dover from an engineering point of view, and had come to a belief in its feasibility, so far as that could be determined from borings and surveys . Subsequently, however, he became convinced that the tunnel would not be to the See also:advantage of Great See also:Britain, and thereafter would have nothing to do with the project .

He was also engineer of the See also:

Severn Tunnel, which, from its magnitude and the difficulties encountered in its construction, must See also:rank as one of the most notable engineering undertakings of the 19th See also:century . Be died in London on the 2nd of See also:June 189r .
