Wulf recognized not only a good story but also an important one. She has written a fascinating book about a fascinating man whose work influences our thinking even though his name is no longer widely remembered.
Wulf knows her subject well, but her book, divided between a biography of his life and sections tracing his influence on Thomas Jefferson, Simon Bolivar, Charles Darwin, Henry David Thoreau, John Muir, and others, sometimes feels disjointed. She is at her best in her vivid and exciting chapters describing Humboldt’s epic travels.
