Isambard Kingdom Brunel FRS (9 April 1806 – 15 September 1859), was a mechanical and civil engineer who is considered "one of the most ingenious and prolific figures in engineering history", "one of the 19th century engineering giants", and "one of the greatest figures of the Industrial Revolution, He changed the face of the English landscape with his groundbreaking designs and ingenious constructions". Brunel built dockyards, the Great Western Railway, a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering.
During his career, Brunel achieved many engineering firsts, including assisting in the building of the first tunnel under a navigable river and development of SS Great Britain, the first propeller-driven, ocean-going, iron ship, which, when built in 1843, was the largest ship ever built.
Brunel astonished Britain by proposing to extend the Great Western Railway westward to North America by building steam-powered, iron-hulled ships. He designed and built three ships that revolutionised naval engineering: the SS Great Western (1838), the SS Great Britain (1843), and the SS Great Eastern (1859).
