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. 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.

Drawing on contemporary accounts, this, the first full modern biography of Telford, at once intimate and expansive, is an utterly original portrait. It is a book of roads and landscapes, waterways and bridges, but above all, of how one man transformed himself into the greatest engineer Britain has ever produced.

Coming to Ludlow Assembly Rooms to reveal Telford's story is Julian Glover: a journalist, speechwriter and special adviser. Previously a columnist for the Guardian, in 2011 he was appointed chief speechwriter to David Cameron before in 2012 being made special adviser in the UK Department for Transport. He is married to The Times columnist and former Conservative MP Matthew Parris.
