Isambard Kingdom Brunel 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. "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
Isambard Kingdom Brunel drove away investors, leaving no money for the project, and construction ceased. 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
