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 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 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 him a lifetime pension.

The Map That Changed the World is, at its foundation, a tale of endurance and achievement, of one man's dedication in the face of ruin and homelessness. The world's coal and oil industry, its gold mining, its highway systems, and its railroad routes were all derived entirely from the creation of Smith's first map.; and with a keen eye and thoughtful detail, Simon Winchester unfolds the poignant sacrifice behind this world-changing discovery.

"With descriptive contemporary visitations to places significant to the story and well-chosen historical detail, he makes immediate not only the magnitude and elegance of Smith's accomplishment, but also the thrill of each of the moments of genius necessary to reach his ultimate conclusion. Smith's life provides a terrific plot to frame his contribution to science. Winchester's wonderful account does credit to it." — Publishers Weekly (*Starred Review*)

In 1793, a canal digger named William Smith made a startling discovery. He found that by tracing the placement of fossils, which he uncovered in his excavations, one could follow layers of rocks as they dipped and rose and fell—clear across England and, indeed, clear across the world—making it possible, for the first time ever, to draw a chart of the hidden underside of the earth. Smith spent twenty-two years piecing together the fragments of this unseen universe to create an epochal and remarkably beautiful hand-painted map. But instead of receiving accolades and honors, he ended up in debtors' prison, the victim of plagiarism, and virtually homeless for ten years more.

The Map That Changed the World is a very human tale of endurance and achievement, of one man's dedication in the face of ruin. With a keen eye and thoughtful detail, Simon Winchester unfolds the poignant sacrifice behind this world-changing discovery.

In 1793, British canal digger William Smith noticed that the rocks he was excavating were arranged in layers, and that the fossils found in one layer were very different from those found in another. Determined to create a map that would display this hidden underside of England, he spent 20 years traveling the country and studying rock outcrops and fossils. In 1815, Smith published his groundbreaking geological map. But in a cruel twist of fate, his work was plagiarized and he was soon in debtors’ prison.

Simon Winchester, author of The Professor and the Madman, tells the fascinating story of Smith’s remarkable scientific achievement, fall from grace and ultimate recognition as the father of modern geology. This New York Times bestseller is a tale of endurance and achievement, of one man’s dedication in the face of personal crisis and how his work helped create the world that we know today.
