Humboldt’s Naturgemälde, also known as the Chimborazo Map
Humboldt’s depiction of the volcanoes Chimborazo and Cotopaxi in cross section, with detailed information about plant geography. The illustration was published in The Geography of Plants in 1807, in a large format (54 cm x 84 cm). Largely used for global warming analyses, this map depicts, in fact, the vegetation of another volcano: the Antisana.

Humboldt was a pioneer of scientific explanation by visualization, using images to convey complex ideas in a way that had not been explored before. Humboldt’s work was on climate and the distribution of plants and animals, but others soon began mapping many other aspects of human life such as disease, poverty and so on.
The most accurate map of New Spain (now Mexico) to date was created by Humboldt and published in his Essai politique sur le royaume de la Nouvelle-Espagne (Political Essay on the Kingdom of New Spain) in 1811. Humboldt’s Carte du Mexique (1804) was based on existing maps of Mexico, Humboldt paid special attention to latitude and longitude. Landing at the Pacific coast port of Acapulco in 1803, Humboldt did not leave the port area for Mexico City until he produced a map of the port. When leaving he drew a map of the east coast port of Veracruz, as well as a map of the central plateau of Mexico. Given royal authorization from the Spanish crown for his trip, crown officials in Mexico were eager to aid Humboldt’s research. He had access to José Antonio de Alzate y Ramírez’s Mapa del Arzobispado de México (1768), which he deemed ‘very bad’, as well as the 17th century map of greater Mexico City by savant Don Carlos de Sigüenza y Góngora.[WP]
The Greenwich prime meridian became the international standard reference for cartographers in 1884.
Humboldt’s work was not just a highly original scientific magnum opus, but a conscious and deliberate attempt to explore the human imagination by grasping, in transparent prose, the mystery, majesty, and wonder of the natural world. It is science as a celebration of existence.
The excitement and poetry of his enterprise, its Romantic exuberance, ensured the popular appeal that won him international fame. Even among his peers he was regarded as the greatest scientist of his day. His narrative was acclaimed by some of the world’s all-time literary masters – the English Romantic poets and the German genius Goethe.
Though his scientific work would be eclipsed by the publication, in the year of his death, of Darwin’s ‘On the Origin . . . ‘, his presence was evident in Darwin’s use of engaging and insightful expression, perhaps the most notable being the meditative concluding paragraph of ‘On the Origin . . . ‘, which was Darwin’s cryptic tribute to his inspirational scientist-explorer hero.
Humboldt was a field scientist, what today we would call an ecologist, whose work was complemented by laboratory-based German experimental physiologists. The early 19th century thus became a new and third phase in humanity’s study of plants moving beyond descriptive botany as nomenclature, classification, and description and into plant science proper, as the experimental study of physiology, development, and ecology. In simple terms, it was a transition in emphasis from structure to function.

Phase 1 – Plant medicine
Plants in relation to humans
The first phase, which persisted into modernity, was about plant utility – concerned with plant use as food, materials, and medicines. In spite of the daily need for plant-based food it was the medicinal use of plants that acquired special significance. Plant powers (medicinal properties) were regarded as a manifestation of the supernatural and they could quickly change human lives for better or worse. The manipulation of these powers required mediators who possessed the special (often secret) knowledge of how to release these powers. Then there was also the role of the bearer of plant wisdom in mediating between the human and spirit worlds. A crude lineage can then be drawn between the shaman/medicine man, priest/scribe, apothecary/physician, academic/plant scientist.
Phase 2 – Botany
Plants in relation to plants
The second phase (with a brief interlude in the Lyceum of ancient Greece focused on plants themselves) entailed the systematization of plant knowledge, at first in relation to their medicinal properties (materia medica, herbals) but then in the refinement of their morphological structure and categorization into kinds. The advent and proliferation of printing through the 15th and 16th centuries, facilitated the sharing of information and standardization of terminology and it was at this time in history when botany diverged from medicine as medicinal botany followed one path into pharmacology and descriptive botany began its academic march towards plant science proper.
Botany then, by this understanding, consisted of the description and organization of the plant kingdom. It was the foundational inventory required before furtherr study could be pursued. Scientifically it entailed the standardization of methods and terms within a specialist plant group within the general scientific community. The emphasis of the study of botany was not on plant utility but the plants themselves: it was about plants in relation to plants as botany extricated itself from medicine to become a discrete academic discipline that persisted in this form until the early 19th century.
Phase 3 – Plant science
Plants in relation to nature
The third phase, ushered in by von Humbolt, placed emphasis on plants in relation to nature (the environment). This was botany coming of age in Industria as study moved from plant structure to plant process and change: it was a phase centred in Germany that eventually moved to Britain. While Humboldt, in the field, laid the foundations for a future ecology, his German colleagues experimented in laboratories to establish the principles of plant physiology and development. The study of plants had now evolved from static ‘botany’ to dynamic ‘plant science’ – from taxonomy, histology, and morphology, to physiology and ecology. This set the stage for the master of change, Charles Darwin, to reconfigure the entire field of biology.
Phase 4 – Plants & the future of humanity
Plants & the future
With the arrival of Informatia in the mid- 20th century, the study of plants has taken yet another turn. Plant science had solved, in principle, all the former mysteries of plant structure and function. No doubt this contributed to the advent of the Anthropocene, an era dominated by an exploding human population and its consumption. With the cracking of the genetic code, arrival of computers, information technology, globalization, and the environmental demands of human consumption, the former three phases have now been harnessed to address the future of humanity by investigating plants more deeply than ever before at the macro- and micro-scales. Environmental concern has harnessed global ecology to address climate change, species extinction, and environmental degradation of the biosphere, integrated with plant microbiology has been harnessed to address food security and the effective completion of an account of the community of life etc. What has transpired is that a large proportion of plant science is now addressing the complex global analysis and management of the place of plants in human ecology.

This expedition completes the meteorological data for his isothermal world map. With C.G. Ehrenberg and Gustav Rose, traveled across the vast expanse of the Russian empire, the results published by Ehrenberg and Rose. His own work on this expedition was the three-volume descriptive geography Asie Centrale published much later. This work was very modest in comparison to Humboldt’s South American publications.

- Humboldt’s intellectual influences included Enlightenment ideals, German Romanticism and Idealism, the philosophy of Immanuel Kant, and the Naturphilosophie of Schelling
- His major contributions were in physical geography, biogeography, and meteorology
- His ideas ranged across plant geography, landscape change, purpose in nature, the contemporary influence of physical reductionism, the use of analysis and synthesis as alternative scientific methods, biological and social globalization, and the multidisciplinary connectedness of all things as perceived by the human mind
- His major thoughts on plant geography were distilled in his Essay on the geography of plants and its famous illustration, the Naturgemälde. This was a new field botany, the latent ecology that complemented the pioneering laboratory studies of plant physiology that were being led by German botanists at this time
- In 1842, Schleiden’s Principles of scientific botany revolutionized future plant study by marking, in effect, the transition from descriptive botany to experimental plant science
- In the first half of the 19th century, with the combined studies of field scientist Humboldt and laboratory-based German experimental plant physiologists, the study of plants moved into a third phase . . . beyond plants as medicines, and descriptive structural botany (as nomenclature, classification, and description), to plant science proper – the experimental study of plant function (as physiology, development, and ecology).
