Elli H. Radinger , born in 1951, gave up her profession as a lawyer to devote herself entirely to writing and to wolves, her passion. She is now Germany's best-known expert on wolves and shares her knowledge in books, seminars and lectures. For twenty-five years she has spent a large part of every year observing wild wolves in the Yellowstone National Park in Wyoming, USA. The Wisdom of Wolves is her first book.
