Author’s Note
Alexander von Humboldt’s books have been published in many languages. When quoting from his books directly, I have compared the original German (where applicable) and contemporary English editions. Where newer English editions have been available, I have checked those against the older translations and where I felt that the newer edition provided a better translation, I have chosen that version (details are in the endnotes). Sometimes neither translation captured Humboldt’s prose, or whole sentences were missing – in which case I have taken the liberty of providing a new translation. When other protagonists referred to Humboldt’s work, I have used the editions that they were reading. Charles Darwin, for example, read Humboldt’s Personal Narrative that was published in Britain between 1814 and 1829 (translated by Helen Maria Williams), while John Muir read the 1896 edition (translated by E.C. Otte and H.G. Bohn).
