From the late nineteenth century until World War II, competing spheres of professional identity and practice redrew the field of history, establishing fundamental differences between the roles of university historians, archivists, staff at historical societies, history teachers, and others. In History’s Babel, Robert B. Townsend takes us from the beginning of this professional shift—when the work of history included not just original research, but also teaching and the gathering of historical materials—to a state of microprofessionalization that continues to define the field today. Drawing on extensive research among the records of the American Historical Association and a multitude of other sources, Townsend traces the slow fragmentation of the field from 1880 to the divisions of the 1940s manifest today in the diverse professions of academia, teaching, and public history. By revealing how the founders of the contemporary historical enterprise envisioned the future of the discipline, he offers insight into our own historical moment and the way the discipline has adapted and changed over time. Townsend’s work will be of interest not only to historians but to all who care about how the professions of history emerged, how they might go forward, and the public role they still can play.

The Endangered Species Act of 1973 (ESA) is one of the most cherished and reviled laws ever passed. It mandates protection and preservation of all the nation’s species and biodiversity, whatever the cost. It has been a lightning rod for controversy and conflicts between industry/business and environmentalists. The year 2023 marks the 50th anniversary of this law, and provides an opportunity for a measured and thorough evaluation thereof. We cannot know today’s challenges and opportunities without understanding their histories. This book is the most comprehensive history of the ESA ever published, and the first to consider the entire history of the law from all angles in a single volume. The history of the ESA has been one of increasing impact, complexity, and controversy. In 1978, the Supreme Court declared that Congress intended for the U.S. government to save all species at any cost, and thereafter application of the ESA became steadily more controversial, as seen in the example of the northern spotted owl and the timber wars in the Pacific Northwest in the late 1980s and early 90s, and then everywhere as the ESA became a political football in the highly partisan environment of the late 1990s and amendments to the law ceased. This book is not only a history, but a call to action. It will take more conservation, more funding, and more innovative solutions if we are to save our wildlife and biodiversity. It will take the engagement to every American to muster the collective will to meet this challenge. The hope of this book is that we will be able to look back and say that we accomplished more in the second 50 years of the ESA than we did in the first.

The rapid growth of the American environmental movement in recent decades obscures the fact that long before the first Earth Day and the passage of the Endangered Species Act, naturalists and concerned citizens recognized—and worried about—the problem of human-caused extinction. As Mark V. Barrow reveals in Nature’s Ghosts, the threat of species loss has haunted Americans since the early days of the republic. From Thomas Jefferson’s day—when the fossil remains of such fantastic lost animals as the mastodon and the woolly mammoth were first reconstructed—through the pioneering conservation efforts of early naturalists like John James Audubon and John Muir, Barrow shows how Americans came to understand that it was not only possible for entire species to die out, but that humans themselves could be responsible for their extinction. With the destruction of the passenger pigeon and the precipitous decline of the bison, professional scientists and wildlife enthusiasts alike began to understand that even very common species were not safe from the juggernaut of modern, industrial society. That realization spawned public education and legislative campaigns that laid the foundation for the modern environmental movement and the preservation of such iconic creatures as the bald eagle, the California condor, and the whooping crane. A sweeping, beautifully illustrated historical narrative that unites the fascinating stories of endangered animals and the dedicated individuals who have studied and struggled to protect them, Nature’s Ghosts offers an unprecedented view of what we’ve lost—and a stark reminder of the hard work of preservation still ahead.
