<human>:  With regards to the history of ship building, who invented the first iron ship?
<bot>: The first iron ship was built in the late 19th century. It was called the SS Great Eastern. It was built by the famous British shipbuilder, Isambard Kingdom Brunel. It was designed to be the world’s largest ship, but it never sailed. It was built in 1858, but the ship was too big and too heavy to be floated down the Thames River. The ship was eventually broken up and the parts were used to build other ships.
