Gabriel Finkelstein’s new book explores the life and work of Emil du Bois-Reymond, “the most important forgotten intellectual of the nineteenth century.” The beautifully written book introduces readers to diary pages and love letters, laboratory equipment and frog pistols. Whether he’s busy conducting electrical experiments or avoiding his underwear-proffering mother-in-law, du Bois-Reymond is a pleasure to read about.
