The number one New York Times best seller by Pulitzer Prize-winning historian David McCullough rediscovers an important chapter in the American story that's "as resonant today as ever" (The Wall Street Journal) - the settling of the Northwest Territory by courageous pioneers who overcame incredible hardships to build a community based on ideals that would define our country.

Alexander von Humboldt (1769-1859) was an intrepid explorer and the most famous scientist of his age. His restless life was packed with adventure and discovery, whether climbing the highest volcanoes in the world or racing through anthrax-infested Siberia. He came up with a radical vision of nature, that it was a complex and interconnected global force and did not exist for man's use alone. Ironically, his ideas have become so accepted and widespread that he has been nearly forgotten.

A landmark in travel writing, this is the incredible true story of Heinrich Harrer’s escape across the Himalayas to Tibet, set against the backdrop of the Second World War. Heinrich Harrer, already one of the greatest mountaineers of his time, was climbing in the Himalayas when war broke out in Europe. He was imprisoned by the British in India but succeeded in escaping and fled to Tibet.

Against the background of an age that saw the rebirth of ancient and classical learning, Paul Strathern explores the intensely dramatic rise and fall of the Medici family in Florence as well as the Italian Renaissance, which they did so much to sponsor and encourage. Interwoven into the narrative are the lives of many of the great Renaissance artists with whom the Medici had dealings, including Leonardo, Michelangelo, and Donatello as well as scientists like Galileo and Pico della Mirandola.

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.

"I am hopelessly and forever a mountaineer," John Muir wrote. "Civilization and fever and all the morbidness that has been hooted at me has not dimmed my glacial eye, and I care to live only to entice people to look at Nature's loveliness. My own special self is nothing". In Donald Worster's magisterial biography, John Muir's "special self" is fully explored as is his extraordinary ability, then and now, to get others to see the sacred beauty of the natural world.

Who formed the first literate society? Who invented our modern ideas of democracy and free market capitalism? The Scots. As historian and author Arthur Herman reveals, in the 18th and 19th centuries Scotland made crucial contributions to science, philosophy, literature, education, medicine, commerce, and politics - contributions that have formed and nurtured the modern West ever since. This book is not just about Scotland: it is an exciting account of the origins of the modern world.

In 1839 rumors of extraordinary yet baffling stone ruins buried within the unmapped jungles of Central America reached two of the world's most intrepid travelers. Seized by the reports, American diplomat John Lloyd Stephens and British artist Frederick Catherwood sailed together out of New York Harbor on an expedition into the forbidding rainforests of present-day Honduras, Guatemala, and Mexico. What they found would rewrite the West's understanding of human history.

At the heart of the nation's spiritual history are audacious and often violent scenes. But the Puritans and the shining city on the hill give us just one way to understand the United States. Rather than recite American history from a Christian vantage point, Peter Manseau proves that what really happened is worth a close, fresh look.

This intimate biography is the first to focus on Lawrence in his twenties, the untold story of the awkward archaeologist from Oxford who, on first visiting the East, fell in love with Arab culture and found his life's mission. Few people realize Lawrence's classic autobiography, Seven Pillars of Wisdom, was not the first book to carry that iconic title. Lawrence himself burned his original draft. Anthony Sattin here uncovers the story Lawrence wanted to conceal.

In 1849 Heinrich Barth joined a small British expedition into unexplored regions of Islamic North and Central Africa. One by one his companions died, but he carried on alone, eventually reaching the fabled city of gold, Timbuktu. His five-and-a-half-year, 10,000-mile adventure ranks among the greatest journeys in the annals of exploration, and his discoveries are considered indispensable by modern scholars of Africa.

No cloistered don, this tall, married Englishman was a freethinking intellectual, who practiced nudism and was devoted to a quirky brand of folk dancing. In 1937, while working as a biochemist at Cambridge University, he instantly fell in love with a visiting Chinese student, with whom he began a lifelong affair. He soon became fascinated with China, and his mistress swiftly persuaded the ever-enthusiastic Needham to travel to her home country, where he embarked on a series of extraordinary expeditions to the farthest frontiers of this ancient empire.

One day in 1872, self-taught Assyriologist George Smith was sifting through a pile of clay tablets when he realized he was reading about "a flood, storm, a ship caught on a mountain, and a bird sent out in search of dry land". This is the riveting story of the discovery of the world's first literary epic, the "Epic of Gilgamesh".
