Thomas Telford's name is familiar; his story less so. Born in 1757 in the Scottish Borders, his father died in his infancy, plunging the family into poverty. Telford's life soared to span almost eight decades of gloriously obsessive, prodigiously productive energy. Few people have done more to shape our nation.Thomas Telford invented the modern road. A stonemason turned architect turned engineer, he built churches, harbours, canals, docks and the famously vertiginous Pontcysyllte aqueduct in Wales. He created the backbone of our national road network. His bridges are some of the most dramatic and beautiful ever built, most of all the Menai Bridge, a wonder then and now, which spans the dangerous channel between the mainland and Anglesey. His constructions were the most stupendous in Europe for a thousand years, and astonishingly almost everything he ever built remains in use today.
