The Invention of Nature

When nature is perceived as a web, its vulnerability also becomes obvious. Everything hangs together. If one thread is pulled, the whole tapestry may unravel. After he saw the devastating environmental effects of colonial plantations at Lake Valencia in Venezuela in 1800, Humboldt became the first scientist to talk about harmful human-induced climate change. Deforestation there had made the land barren, water levels of the lake were falling and with the disappearance of brushwood torrential rains had washed away the soils on the surrounding mountain slopes. Humboldt was the first to explain the forest’s ability to enrich the atmosphere with moisture and its cooling effect, as well as its importance for water retention and protection against soil erosion. He warned that humans were meddling with the climate and that this could have an unforeseeable impact on ‘future generations’.

The Invention of Nature traces the invisible threads that connect us to this extraordinary man. Humboldt influenced many of the greatest thinkers, artists and scientists of his day. Thomas Jefferson called him ‘one of the greatest ornaments of the age’. Charles Darwin wrote that ‘nothing ever stimulated my zeal so much as reading Humboldt’s Personal Narrative,’ saying that he would not have boarded the Beagle

, nor conceived of the Origin of Species, without Humboldt. William Wordsworth and Samuel Taylor Coleridge both incorporated Humboldt’s concept of nature into their poems. And America’s most revered nature writer, Henry David Thoreau, found in Humboldt’s books an answer to his dilemma on how to be a poet

and a naturalist – Walden

would have been a very different book without Humboldt. Simón Bolívar, the revolutionary who liberated South America from Spanish colonial rule, called Humboldt the ‘discoverer of the New World’ and Johann Wolfgang von Goethe, Germany’s greatest poet, declared that spending a few days with Humboldt was like ‘having lived several years’.

On 14 September 1869, one hundred years after his birth, Alexander von Humboldt’s centennial was celebrated across the world. There were parties in Europe, Africa and Australia as well as the Americas. In Melbourne and Adelaide people came together to listen to speeches in honour of Humboldt, as did groups in Buenos Aires and Mexico City. There were festivities in Moscow where Humboldt was called the ‘Shakespeare of sciences’, and in Alexandria in Egypt where guests partied under a sky illuminated with fireworks. The greatest commemorations were in the United States, where from San Francisco to Philadelphia, and from Chicago to Charleston, the nation saw street parades, sumptuous dinners and concerts. In Cleveland some 8,000 people took to the streets and in Syracuse another 15,000 joined a march that was more than a mile long. President Ulysses Grant attended the Humboldt celebrations in Pittsburgh together with 10,000 revellers who brought the city to a standstill.

In New York City the cobbled streets were lined with flags. City Hall was veiled in banners, and entire houses had vanished behind huge posters bearing Humboldt’s face. Even the ships sailing by, out on the Hudson River, were garlanded in colourful bunting. In the morning thousands of people followed ten music bands, marching from the Bowery and along Broadway to Central Park to honour a man ‘whose fame no nation can claim’ as the New York Times’s front page reported. By early afternoon, 25,000 onlookers had assembled in Central Park to listen to the speeches as a large bronze bust of Humboldt was unveiled. In the evening as darkness settled, a torchlight procession of 15,000 people set out along the streets, walking beneath colourful Chinese lanterns.

Let us imagine him, one speaker said, ‘as standing on the Andes’ with his mind soaring above all. Every speech across the world emphasized that Humboldt had seen an ‘inner correlation’ between all aspects of nature. In Boston, Emerson told the city’s grandees that Humboldt was ‘one of those wonders of the world’. His fame, the Daily News in London reported, was ‘in some sort bound up with the universe itself’. In Germany there were festivities in Cologne, Hamburg, Dresden, Frankfurt and many other cities. The greatest German celebrations were in Berlin, Humboldt’s hometown, where despite torrential rain 80,000 people assembled. The authorities had ordered offices and all government agencies to close for the day. As the rain poured down and gusts chilled the air, the speeches and singing nonetheless continued for hours.
