Samuda Brothers was an engineering and ship building firm at Cubitt Town on the Isle of Dogs in London, founded by Jacob and Joseph d'Aguilar Samuda. The site is now occupied by Samuda Estate.
Samuda Brothers began work at Orchard Place, Leamouth, London in 1843, by the mouth of Bow Creek. The firm moved to Cubitt Town in 1852, having outgrown a site that was hemmed in by other industrial premises. By this time the company was run by Joseph, Jacob having been killed in the trial of the Gipsy Queen. The Cubitt Town yard specialised in iron and steel warships and steam packets and by 1863 was said to be producing double the output of the other London shipyards combined. Orders from Germany, Russia and Japan enabled the firm to survive the 1866 financial crisis which affected many other London yards.
In 1877 Togo Heihachiro, later a prominent Japanese admiral, came for work experience with the Samuda Brothers after completing his training at Naval Preparatory School in Portsmouth, and the Royal Naval College at Greenwich. He supervised the construction of the Fusō before returning to Japan. He led the Imperial Japanese navy to victory in the Russo-Japanese War, establishing Japan as a Great Power.
