Book excerpt: This book presents a biography of the Danish botanist Eugen Warming. As the author of a treatise on ecology that brought him international recognition, he was able to inspire the first generation of 20th-century European and American ecologists. His innovative approach to nature and his Arctic and tropical missions heralded the birth of a new science and an ecological awareness. As a professor at several Scandinavian universities during a period of intense debate and controversy over evolutionary theories, Eugen Warming vigorously asserted his convictions. Birth of Scientific Ecology presents the image of a man of knowledge and power, recognized by his contemporaries as a founder of ecology and a player in the ecological project of the Kingdom of Denmark at a time when the empires were clashing.
