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 to England. Brunel worked for several years as an assistant engineer on the project to create a tunnel under London's River Thames between Rotherhithe and Wapping, with tunnellers driving a horizontal shaft from one side of the river to the other under the most difficult and dangerous conditions. The project was funded by the Thames Tunnel Company and Brunel's father, Marc, was the chief engineer. The "American Naturalist" said "It is stated also that the operations of the Teredo [Shipworm] suggested to Mr. Brunel his method of tunneling the Thames." The composition of the riverbed at Rotherhithe was often little
