Described by Charles Darwin as "the greatest scientific traveller who ever lived," Alexander von Humboldt helped to transform western science in the nineteenth century. Naturalist, botanist, zoologist, author, cartographer, artist, and sociologist, he is widely respected as the founder of physical geography (and climatalogy), and his influence on all branches of natural science still persists today.

Ludmilla Assing, the niece of Varnhagen von Ense, was the editor of this selection of letters from Alexander von Humboldt to her uncle - to who Humboldt had entrusted the preservation of their correspondence - in the period 1827-58. First published in 1860, Letters of Alexander von Humboldt also contains letters from Varnhagen and other distinguished correspondents to Humboldt. Some passages from Varnhagen's diary are also included to supply a vivid commentary on the letters, which present detailed records of Humboldt's life, activity, and habits of thought, and contain materials of unquestionable importance for portraying an accurate picture of his mind and character. The other letters contained in the volume illustrate his worldwide circle of correspondents. This collection was published after the deaths of both Varnhagen and Humboldt. Explanatory notes and a full index of names accompany this authorised translation from the original German.

Alexander von Humboldt was the most celebrated modern chronicler of North and South America and the Caribbean, and this translation of his essay on New Spain--the first modern regional economic and political geography--covers his travels across today's Mexico in 1803-04. The work canvases both natural-scientific and cultural-scientific objects alike, combining the results of fieldwork with archival research and expert testimony. To show how people, plants, animals, goods, and ideas moved across the globe, Humboldt wrote in a variety of styles, bending and reshaping familiar writerly conventions to keep readers attentive to new inputs. Above all, he wanted his readers to keep an open mind when confronted with cultural and other differences in the Americas. Fueled by his comparative global perspective on politics, economics, and science, he used his writing to support Latin American independence and condemn slavery and other forms of colonial exploitation. It is these voluminous and innovative writings on the New World that made Humboldt the undisputed father of modern geography, early American studies, transatlantic cultural history, and environmental studies. This two-volume critical edition--the third installment in the Alexander von Humboldt in English series--is based on the full text, including all footnotes, tables, and maps, of the second, revised French edition of Essai politique sur le royaume de de Nouvelle Espagne from 1825-27, which has never been translated into English before. Extensive annotations and full-color atlases are available on the series website.

The acclaimed Prussian naturalist Alexander von Humboldt (1769-1859) was referred to by Charles Darwin as 'the greatest scientific traveller who ever lived'. Several of his works were in the library aboard the Beagle, including the multi-volume Personal Narrative of Travels, two books on geology and Tableaux de la nature (all reissued in the Cambridge Library Collection). Darwin's copy of this two-volume 1811 New York edition of Humboldt's Political Essay (originally published in French earlier that year) is inscribed 'Buenos Ayres', suggesting he acquired it there in 1832-3, without its accompanying atlas (forthcoming). Humboldt had spent a year in Mexico in 1803-4, and was struck by its 'civilization' as compared to regions of South America that he had visited earlier on his expedition. Volume 1 of his account contains a 'geographical introduction' and discussions of physical geography, agriculture, and the ethnic diversity, distribution and health of the population.

The explorer and multi-disciplinary scientist Alexander von Humboldt (1769 1859) was a prominent figure in the European scientific community of the eighteenth and nineteenth centuries and the first to make a scientific survey of South and Central America. His travels alone brought him widespread recognition, but the extensive field notes and research he undertook were developed further on his return. Originally published in French and translated in 1823, this work brought his geological speculations to a British audience. Humboldt explores the positioning of different types of rocks across the globe, and the causes behind these formations. He also hypothesises that the flora of these areas are affected by the geology, which in turn is influenced by the thermal currents of the earth's molten core. These insights into rock formations are also key to Humboldt's theory of continental drift, now recognised as resulting from the shifting of the continental plates.

Alexander von Humboldt (1769-1859) was an intellectual giant: an explorer who helped lay the foundations of biogeography, a naturalist who influenced Charles Darwin, and a botanist who developed a model of the Earth's climate zones. He travelled extensively in Europe, carried out scientific explorations across the Russian Empire and in Latin America, and devoted much energy to seeking a unified view of the different branches of scientific knowledge. Ansichten der Natur, published in 1808 with a second edition in 1826, aimed to 'engage the imagination' as well as to communicate new ideas, and was translated into many European languages. This authorised translation of the third and final 1849 edition, dating from Humboldt's eightieth year, was published in 1850, though another English translation (by Mrs Sabine) had appeared the previous year. The wide coverage, including geology, geography and biology, is typical of Humboldt, as is the precise and engaging style.

Alexander von Humboldt (1769 1859) was one of the most respected scientists of his time; Darwin called him 'the greatest scientific traveller who ever lived'. From 1799 Humboldt spent five years exploring the Americas, reporting his findings in thirty volumes, published over a period of more than twenty years from 1805. His Essai Politique, describing northern New Spain, particularly Mexico, was one of the first studies of a single country written to take account of both its history, its society and its political development. In 1824, the English mining engineer John Taylor published this abridged translation, combining it with passages from Humboldt's Geognostical Essay on the Superposition of Rocks in order to provide a focussed account of Mexico's mining concerns and opportunities. Including detailed maps, this work contains exhaustive statistics, particularly with regard to trade, agriculture and mining, alongside geographical studies and observations on the population and government.

Alexander von Humboldt (1769 1859) was an internationally respected scientist and explorer whose meticulous approach to scientific observation greatly influenced later research. He travelled the world, once staying at the White House as a guest of Thomas Jefferson, and is commemorated in the many species and places which bear his name. This two volume work, published in French in 1810 as Vue des Cordill res, and in this English translation in 1814, was one of the many publications that resulted from Humboldt's expedition to Latin America in 1799 1804. It describes geographical features such as volcanoes and waterfalls, and aspects of the indigenous cultures including architecture, sculpture, art, languages and writing systems, religions, costumes and artefacts. This approachable, closely observed travelogue vividly recounts a huge variety of impressions and experiences, and reveals Humboldt's boundless curiosity as well as his scientific and cultural knowledge.

The Prussian naturalist Alexander von Humboldt (1769-1859) was one of the most famous explorers of his generation. Charles Darwin called him 'the greatest scientific traveller who ever lived'. In 1799, Humboldt and the botanist Aime Bonpland secured permission from the Spanish crown for a voyage to South America. They left from Madrid and spent five years exploring the continent. Humboldt reported his findings in a total of thirty volumes, published in French over a period of more than twenty years beginning in 1805. This English translation by Helen Maria Williams of one important component of Humboldt's account, the Relation historique du voyage (1814-1825), consists of seven volumes and was published in London between 1814 and 1829. Volume 1 describes the beginning of the expedition, its departure from Spain, experiments conducted on board ship, and the scientists' arrival in the Canary Islands and exploration of Tenerife.

Polymath Alexander von Humboldt (1769 1859), a self-described 'scientific traveller', was one of the most respected scientists of his time. Humboldt's wanderlust led him across Europe and to South America, Mexico, the U.S., and Russia, and his voyages and observations resulted in the discovery of many species previously unknown to Europeans. Originating as lectures delivered in Berlin and Paris (1827 1828), his multi-volume Cosmos: Sketch of a Physical Description of the Universe (1845 1860) represented the culmination of his lifelong interest in understanding the physical world. As Humboldt writes, 'I ever desired to discern physical phenomena in their widest mutual connection, and to comprehend Nature as a whole, animated and moved by inward forces.' Volume 1 (1846) investigates celestial and terrestrial phenomena, from nebulae to the temperature of the earth, as well as 'organic life'. Throughout, he stresses the method of, and limits to, describing the universe's physical nature.

As Humboldt writes, 'I ever desired to discern physical phenomena in their widest mutual connection, and to comprehend Nature as a whole, animated and moved by inward forces'. Volume 2 (1848) reviews poetic descriptions of nature as well as landscape painting from antiquity through to modernity, before using the same time-span to examine a 'History of the Physical Contemplation of the Universe'.

The first volume of "Cosmos," his five-volume survey of the universe, appeared in 1845, though Humboldt had labored on the entire work for nearly half a century. He scrupulously sent sections of the work to other experts for suggestions and corrections. The last volume, put together from his notes after his death, appeared in 1861. The volumes were translated almost as rapidly as they appeared. This paperback edition reprints the Harper & Brothers edition, published in New York in 1858-59.

Linguistic Variability and Intellectual Development, Wilhelm von Humbolt's most famous work, was published by his brother Alexander posthumously, in 1836. It promptly established itself as a classic in the philosophy of language and has held that position ever since. With many examples from a vast multitude of languages, from Sanskrit to Delaware Indian, the author shows how character and structure of a language expresses the inner life and knowledge of its speakers and how their intellectual development is in turn shaped by their language.
