H. WALTER LACK is a professor at the Free University of Berlin. He is the author of numerous books on botanical illustrations, including Jardin de la Malmaison: Empress Josephine's Garden and Florilegium Imperiale (both by Prestel).
"The book has beautiful illustrations of his journeys, including when he climbed what was then believed to be the world's tallest peak, Chimborazo in Ecuador. The real gems in the book, however, are the richly colored prints of artistic renderings of the plants he documented along the way, as well as photographs of the specimens he retained for study in Europe." -Daily Beast
