John Loudon McAdam was a Scottish civil engineer who revolutionized road building in the early 19th century. He developed the macadam process, layering crushed stone for improved durability and drainage. As highway engineer for several British counties, he advocated for better infrastructure to support trade and travel. The term “macadamization” and later “tarmac” derive from his name and his techniques formed the basis of modern roads. McAdam’s innovations facilitated the Industrial Revolution and left a lasting legacy in civil engineering until his death in 1836.
