Aaron Manby was a landmark vessel in the science of shipbuilding as the first iron steamship to go to sea. She was built by Aaron Manby (1776–1850) at the Horseley Ironworks. She made the voyage to Paris in June 1822 under Captain (later Admiral) Charles Napier, with Aaron's son Charles on board as engineer. Aaron Manby was then used by the "Compagnie des bateaux a vapeur en fer" to operate its service between Paris and Havre.
