John Scott Russell

Died 8 Jun 1882 at age 74 (born 8 May 1808). British civil engineer best known for researches in ship design. He designed the first seagoing battleship built entirely of iron. He was the first to record an observation of a soliton, while conducting experiments to determine the most efficient design for canal boats. In Aug 1834, he observed what he called the “Wave of Translation,” a solitary wave formed in the narrow channel of a canal which continues ahead after a canal boat stops. He also made the first experimental observation of the “Doppler shift” of sound frequency as a train passes (1848). He designed (with Brunel) the Great Eastern and built it; he designed the Vienna Rotunda and helped to design Britain's first armoured warship, the Warrior.
