Goethe compared Humboldt to a ‘fountain with many spouts from which streams flow refreshingly and infinitely, so that we only have to place vessels under them’.
That fountain, I believe, has never run dry.
During 2013, I was the British Library Eccles Writer in Residence. It was the most productive year I have ever had in my writing career. I loved every moment of it. Thank you to everybody at the Eccles Centre – in particular Philip Davis, Jean Petrovic and Cara Rodway, as well as Matt Shaw and Philip Hatfield at the British Library. Thank you!
Over the past few years, I have received so much assistance from so many people that I feel humbled by their generosity. Thank you all for making the research and writing of this book the most wonderful experience. So many shared their knowledge and research, read chapters, opened address books, followed up on my queries (many times) and made me welcome across the world – it made this a proper Humboldtian experience of global networks.

A very special and massive thank you to my wonderful friend and agent Patrick Walsh, who has wanted me to write a book about Alexander von Humboldt for more than a decade, and who first took me to Venezuela ten years ago. You’ve worked so unbelievably hard on this – line by line. This would have been a very different book without you. And thank you for believing in me and for looking after me. Without you, I would have a lot less fun in life and be without a job.
And a huge thank you to my friends and family who patiently endured my Humboldt fever:
