Thames Ironworks and Shipbuilding and Engineering Co Ltd x Ditchburn and Mare Shipbuilding Co x C J Mare and Co

The Thames Ironworks and Shipbuilding and Engineering Company Limited was founded in 1837 by shipbuilder Thomas Ditchburn and naval architect Charles Mare as the Ditchburn and Mare Shipbuilding Company, then C.J. Mare and Company. The shipyards were first at Deptford, then moved to Orchard Creek. They were one of the first builders of iron ships. They built several warships for the Admiralty including HMS Warrior. Their employee football club, Thames Ironworks FC, later became West Ham United FC. The Ironworks closed in 1912, unable to compete with northern shipyards.
