Isambard Kingdom Brunel, FRS (9 April 1806 - 15 September 1859), was a leading British civil engineer, famed for his bridges and dockyards, and especially for the construction of the first major British railway, the Great Western Railway; a series of famous steamships, including the first propeller-driven transatlantic steamship; and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering. Though Brunel's projects were not always successful, they often contained innovative solutions to long-standing engineering problems. During his short career, Brunel achieved many engineering 'firsts', including assisting in the building of the first tunnel under a navigable river and the development of the SS Great Britain, the first propeller-driven ocean-going iron ship, which was at the time (1843) also the largest ship ever built.
