The Map That Changed the World

From the author of the bestselling The Professor and the Madman comes the fascinating story of William Smith, the orphaned son of an English country blacksmith, who became obsessed with creating the world’s first geological map and ultimately became the father of modern geology.

In 1793 William Smith, a canal digger, made a startling discovery that was to turn the fledgling science of the history of the earth — and a central plank of established Christian religion — on its head. He noticed that the rocks he was excavating were arranged in layers; more important, he could see quite clearly that the fossils found in one layer were very different from those found in another. And out of that realization came an epiphany: that by following the fossils, one could trace layers of rocks as they dipped and rose and fell — clear across England and, indeed, clear across the world. Determined to publish his profoundly important discovery by creating a map that would display the hidden underside of England, he spent twenty years traveling the length and breadth of the kingdom by stagecoach and on foot, studying rock outcrops and fossils, piecing together the image of this unseen universe.

In 1815 he published his epochal and remarkably beautiful hand-painted map, more than eight feet tall and six feet wide. But four years after its triumphant publication, and with his young wife going steadily mad to the point of nymphomania, Smith ended up in debtors’ prison, a victim of plagiarism, swindled out of his recognition and his profits. He left London for the north of England and remained homeless for ten long years as he searched for work. It wasn’t until 1831, when his employer, a sympathetic nobleman, brought him into contact with the Geological Society of London — which had earlier denied him a fellowship — that at last this quiet genius was showered with the honors long overdue him. He was summoned south to receive the society’s highest award, and King William IV offered
