A masterly and beautifully written account of the impact of Alexander von Humboldt on nineteenth-century American history and culture The naturalist and explorer Alexander von Humboldt (1769-1859) achieved unparalleled fame in his own time. Today, however, he and his enormous legacy to American thought are virtually unknown. In The Humboldt Current, Aaron Sachs traces Humboldt's pervasive influence on American history through examining the work of four explorers—J. N. Reynolds, Clarence King, George Wallace, and John Muir—who embraced Humboldt's idea of a "chain of connection" uniting all peoples and all environments. A skillful blend of narrative and interpretation that also discusses Humboldt's influence on Emerson, Whitman, Thoreau, Melville, and Poe, The Humboldt Current offers a colorful, passionate, and superbly written reinterpretation of nineteenth-century American history.

A KIRKUS REVIEWS BEST BOOK OF THE YEAR From the New York Times bestselling author of The Invention of Nature, comes a breathtakingly illustrated and brilliantly evocative recounting of Alexander Von Humboldt's five year expedition in South America. 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, but his most revolutionary idea was a radical vision of nature as a complex and interconnected global force that does not exist for the use of humankind alone. His theories and ideas were profoundly influenced by a five-year exploration of South America. Now Andrea Wulf partners with artist Lillian Melcher to bring this daring expedition to life, complete with excerpts from Humboldt's own diaries, atlases, and publications. She gives us an intimate portrait of the man who predicted human-induced climate change, fashioned poetic narrative out of scientific observation, and influenced iconic figures such as Simón Bolívar, Thomas Jefferson, Charles Darwin, and John Muir. This gorgeous account of the expedition not only shows how Humboldt honed his groundbreaking understanding of the natural world but also illuminates the man and his passions.

NATIONAL BESTSELLER • The acclaimed author of Founding Gardeners reveals the forgotten life of Alexander von Humboldt, the visionary German naturalist whose ideas changed the way we see the natural world—and in the process created modern environmentalism. "Vivid and exciting.... Wulf’s pulsating account brings this dazzling figure back into a dazzling, much-deserved focus.” —The Boston Globe Alexander von Humboldt (1769-1859) was the most famous scientist of his age, a visionary German naturalist and polymath whose discoveries forever changed the way we understand the natural world. Among his most revolutionary ideas was a radical conception of nature as a complex and interconnected global force that does not exist for the use of humankind alone. In North America, Humboldt’s name still graces towns, counties, parks, bays, lakes, mountains, and a river. And yet the man has been all but forgotten. In this illuminating biography, Andrea Wulf brings Humboldt’s extraordinary life back into focus: his prediction of human-induced climate change; his daring expeditions to the highest peaks of South America and to the anthrax-infected steppes of Siberia; his relationships with iconic figures, including Simón Bolívar and Thomas Jefferson; and the lasting influence of his writings on Darwin, Wordsworth, Goethe, Muir, Thoreau, and many others. Brilliantly researched and stunningly written, The Invention of Nature reveals the myriad ways in which Humboldt’s ideas form the foundation of modern environmentalism—and reminds us why they are as prescient and vital as ever.

Ocean Currents: Physical Drivers in a Changing World opens with a general introduction to the character, measurement, and simulation of ocean currents, leading to a physical and dynamical framework for understanding the wide variety of flows encountered in the oceans. The book comprises chapters covering distinct aspects of contrasting ocean currents: broad and slow, deep and shallow, narrow and swift, large scale and small scale, low latitudes and high latitudes, and moving in horizontal and vertical planes. Through this approach the authors cover a wide range of applications, from local to global, with considerable geographical context. Provides analyses of ocean observations and numerical model simulations, highlighting the pathways and drift associated with ocean currents, around the World Ocean, linked to online exercises for instructors and students that extend this perspective Presents applications to natural phenomena, showing how ocean currents shape marine ecosystems, helping researchers understand the distribution and adaptation of life in the oceans Addresses societal challenges, specifically how ocean currents disperse pollutants (e.g. plastic) from coastal sources and how the global ocean circulation is central to our changing climate, helping students and researchers develop an interdisciplinary approach to global environmental change

Humboldt offered the world a vision of humans & nature as integrated halves of a single whole. He espoused the idea that while the univerise of nature exists apart from human purpose, its beauty & order are human achievements. Laura Dassow Walls traces the emergence of this philosophy to Humboldt's 1799 journey to America.
