As well as bridges, tunnels and railways, Brunel was responsible for the design of several famous ships. The Great Western, launched in 1837, was the first steamship to cross from Bristol to New York. His ship the Great Britain, launched in 1843, was the world's first 'iron-hulled, screw propeller-driven, steam-powered passenger liner.'
Brunel was a heavy smoker he suffered a stroke and died, aged 53, in 1859, the year his Great Eastern, the biggest ship ever built at that time, was launched.
He is buried at Kensal Green Cemetery in London.
