“I sought out Charlie Berger in the fall of 1975 to meet the man who raised a pair of tundra wolves in rural Vermont. I was impressed then, and I remain impressed now. Dr. Berger rose from the streets of Brooklyn, out of the shadows of World War Two, into an expansive world of Arctic nights and African heat. A veterinarian without an undergraduate degree. A lifelong devotee of Charles Darwin and Alfred Russell Wallace with a self-deprecating sense of humor—Henny Youngman in the outback. A seat-of-the-paints ecotour leader in the mid-sixties when the word “ecotour” had not yet been coined. Charlie's driven back and forth across America 125 times, back and forth to Alaska 48, and lived long enough to recount his life . . . a life well lived.”
