John Wilkinson

John Wilkinson in later years courtesy Iron OakengatesJohn Wilkinson, born near Workington, is a Cumbrian little known to most people today. However, he was well known during the industrial revolution for his involvement in iron works and eventually garnered the title “Iron Mad John” for his experiments with using iron in unconventional ways. He even made his coffin out of iron.

Wilson House courtesy Iron OakengatesHe was educated in Kendal at what was called the Dissenting Academy (the family, not being Anglican, did not want him attending the local school). His father, Isaac, who worked at the Backbarrow Ironworks foundry in Backbarrow, Furness taught him the skills necessary for ironworking. Isaac opened his own ironworks at Wilson House, near Lindale-in-Cartmel, in 1748. John was 20 years old at the time.

After finishing his education John was employed in 1748 at an ironworks in the midlands. In 1753 Isaac moved the rest of his family near Wrexham to run the Bersham company. The business was not a success and caused a falling out between John and his father. Isaac became involved in a south Wales furnace but this business, also, was not successful.

He was left a great deal of money from the marriage and used it to build an industrial empire, encompassing smelting iron, manufacturing lead and iron pipes, steam engines, cannons, barges, and much more. Around 1761 he and other investors took over the Bersham company. Isaac eventually moved to Bristol. In 1763 John married his second wife, Mary Lee, (1724-1806) who brought her fortune to the marriage.

John built an important ironworks at Bradley in south Staffordshire c1766-1770. He also owned ironworks at Willey in Shropshire. In 1777-78 John bought, near Lindale-in-Cartmel, the Castlehead estate and Wilson house with its farm and ironworks (once his father's property). He proceeded to build a mansion at Castlehead. About the same time he built and successfully launched an iron barge.

Backbarrow Furnace courtesy Iron OakengatesHe built an iron bridge across the Severn river at Broseley (one mile from Coalbrookdale). It was opened in 1781. Its 98.5 feet length weighed 378 tons. The bridge was held together with joints, keys, and pegs rather than screws, nuts, and bolts. In 1789 he invented and patented a way of adding spiral grooves to cannon, allowing a cannon ball to have a greater distance and truer aim.

He and his family ended up moving back to Backbarrow. St Paul's church, Lindale, has a plaque dedicated to his wife, Mary, on its south wall. John died in 1808. He was first buried at Castlehead, but his coffin was later removed to Lindale church. Where it is buried there is a mystery.
