John Loudon McAdam, 1830, National Gallery, London. John Loudon McAdam (23 September 1756 26 November 1836) was a Scottish civil engineer and roadbuilder. He invented a new process, "macadamisation", for building roads with a smooth hard surface, using controlled materials of mixed particle size and predetermined structure, that would be more durable and less muddy than soilbased tracks.
