John Horn was born in 1814 in Scotland and began his career in shipbuilding on the Clyde as an apprentice in 1826. He was trained by the famous engineer Robert Napier who was known as the father of iron-ship building. In 1849 he was appointed manager of the Neptune shipyard in Waterford, a position which he held until 1870. Under Horn’s stewardship the Neptune yard prospered, and in its heyday built some of the largest ships in Ireland in those years, including the SS William Penn.
