Robert Howlett in this feat of engineering. This project included the well-known portrait of the "Great Eastern"’s creator and engineer, Isambard Kingdom Brunel, standing in front of the giant launching chains on the 'checking drum' braking mechanism at John Scott Russell’s Millwall shipyard. It was taken to celebrate the launch of the world’s largest steamship, in November 1857. This image, which depicts Brunel in an industrial setting instead of a more traditional background for a portrait, has been described as "one of the first examples of environmental portraiture". Howlett died in 1858, aged 27, at his home and studio at 10 Bedford
Marc Isambard Brunel but this scheme never came to fruition. In 1818 Brunel had patented a tunnelling shield. This was a reinforced shield of cast iron in which miners would work in separate compartments, digging at the tunnel-face. Periodically the shield would be driven forward by large jacks, and the tunnel surface behind it would be lined with brick. It is claimed that Brunel found the inspiration for his tunnelling shield from the shipworm, "Teredo navalis", which has its head protected by a hard shell whilst it bores through ships' timbers. Brunel's invention provided the basis for subsequent tunnelling shields used to build
