His name is virtually unknown in Britain. This year is also his anniversary, his 240th.
Few will have heard of Alexander Von Humboldt, yet he was the most admired naturalist and geographer of his age.
His name lives on in the many species, geographical areas and institutions named after him – 12 species of animals and plants, six prominent geographical features, as well as schools, colleges and even towns. But he was much more than a scientist.
Despite his aristocratic background, he was a radical political thinker.
