There aren’t a lot of books about Humboldt, which I don’t understand, because he was pretty fascinating, but this is a great one. Selsam choose some of the most interesting of Humboldt’s writings, edited them well, and added just enough explanatory material to allow readers to follow the flow of the narrative. Appropriate for middle grades, but interesting enough for adults. Andrea Wulf called Humboldt “the man who invented nature,” and this book gives a glimpse of exactly how he did. Good introductory material, and the whole title was just the right length, coming in under 200 pages all told. Oh, and the multiple maps were much appreciated, and Peterson’s drawings a lovely bonus. Interesting and inspiring.
