A household icon of the environmental movement, Aldo Leopold (1887-1948) may be the most quoted conservationist in history. A Sand County Almanac has sold millions of copies and Leopold's writings are venerated for their perceptions about land and how people might live in concert with the whole community of life.

But who is the man behind the words? How did he arrive at his profound and poetic insights, inspiring generations of environmentalists? Building on past scholarship and a fresh study of Leopold's unpublished archival materials, Julianne Lutz Newton retraces the intellectual journey generated by such passion and intelligence.

Aldo Leopold's Odyssey illuminates his lifelong quest for answers to a fundamental issue: how can people live prosperously on the land and keep it healthy, too? Leopold's journey took him from Iowa to Yale to the Southwest to Wisconsin, with fascinating stops along the way to probe the causes of early land settlement failures, contribute to the emerging science of ecology, and craft a new vision for land use.

More than a biography, this articulate volume is a guide to one man's intellectual growth, and an inspirational resource for anyone pondering the relationships between people and the land.

In 2006, Julianne Lutz Warren (née Newton) asked readers to rediscover one of history’s most renowned conservationists. Aldo Leopold’s Odyssey was hailed by The New York Times as a “biography of ideas,” making “us feel the loss of what might have followed A Sand County Almanac by showing us in authoritative detail what led up to it.” Warren’s astute narrative quickly became an essential part of the Leopold canon, introducing new readers to the father of wildlife ecology and offering a fresh perspective to even the most seasoned scholars.

A decade later, as our very concept of wilderness is changing, Warren frames Leopold’s work in the context of the Anthropocene. With a new preface and foreword by Bill McKibben, the book underscores the ever-growing importance of Leopold’s ideas in an increasingly human-dominated landscape.

Drawing on unpublished archives, Warren traces Leopold’s quest to define and preserve land health. Leopold's journey took him from Iowa to Yale to the Southwest to Wisconsin, with fascinating stops along the way to probe the causes of early land settlement failures, contribute to the emerging science of ecology, and craft a new vision for land use.

Leopold’s life was dedicated to one fundamental dilemma: how can people live prosperously on the land and keep it healthy, too? For anyone compelled by this question, the Tenth Anniversary Edition of Aldo Leopold’s Odyssey offers insight and inspiration.
