How did animal breeding emerge as a movement? Who took part and for what reasons? How do the pedigree and market systems work? What light might the movement shed on the assumptions behind human eugenics? In Bred for Perfection, Margaret Derry provides the most comprehensive and accessible book yet published on the human quest to improve and develop livestock. Derry, herself a breeder and trained historian of science, explores the "triangle" of genetics, eugenics, and practical breeding, focusing on Shorthorn cattle, show dogs and working dogs, and one type of purebred horse, the Arabian. By examining specific breeders and the animals they produced, she illuminates the role of technology, genetics, culture, and economics in the system of purebred breeding. Bred for Perfection also provides the historical context in which this system arose, adding to our understanding of how domestication works and how our welfare-since the dawn of time-has been intertwined with the lives of animals.

In Masterminding Nature, Margaret Derry examines the evolution of modern animal breeding from the invention of improved breeding methodologies in eighteenth-century England to the application of molecular genetics in the 1980s and 1990s. A clear and concise introduction to the science and practice of artificial selection, Derry’s book puts the history of breeding in its scientific, commercial, and social context.Masterminding Nature explains why animal breeders continued to use eighteenth-century techniques well into the twentieth century, why the chicken industry was the first to use genetics in its breeding programs, and why it was the dairy cattle industry that embraced quantitative genetics and artificial insemination in the 1970s, as well as answering many other questions. Following the story right up to the present, the book concludes with an insightful analysis of today’s complex relationships between biology, industry, and ethics.

Chickens are now the most scientifically engineered of livestock. How have the methods used by geneticists differed from those employed by domestic breeders over time? Art and Science in Breeding details the relationship between farm practices and agricultural genetics in poultry breeding from 1850 to 1960.Margaret E. Derry traces the history and organization of chicken breeding in North America, from craft approaches and breeding as an ‘art,’ to the conflicts that had emerged between traditional and scientific methods by the 1940s. Derry assesses links between the 'scientific' revolution of chicken farming and the development of corporate breeding as a modern, international industry. Using poultry as a case study for the wider narrative of agricultural genetics, Art and Science in Breeding adds considerable knowledge to a rapidly growing field of inquiry.

Before crude oil and the combustion engine, the industrialized world relied on a different kind of power - the power of the horse. Horses in Society is the story of horse production in the United States, Britain, and Canada at the height of the species' usefulness, the late nineteenth and early twentieth-century. Margaret E. Derry shows how horse breeding practices used during this period to heighten the value of the animals in the marketplace incorporated a intriguing cross section of influences, including Mendelism, eugenics, and Darwinism.Derry elucidates the increasingly complex horse world by looking at the international trade in army horses, the regulations put in place by different countries to enforce better horse breeding, and general aspects of the dynamics of the horse market. Because it is a story of how certain groups attempted to control the market for horses, by protecting their breeding activities or 'patenting' their work, Horses in Society provides valuable background information to the rapidly developing present-day problem of biological ownership. Derry's fascinating study is also a story of the evolution of animal medicine and humanitarian movements, and of international relations, particularly between Canada and the United States.

Animal breeding has been complicated by persisting factors across species, cultures, geography, and time. In Made to Order, Margaret E. Derry explains these factors and other breeding concerns in relation to both animals and society in North America and Europe over the past three centuries.Made to Order addresses how breeding methodology evolved, what characterized the aims of breeding, and the way structures were put in place to regulate the occupation. Illustrated by case studies on important farm animals and companion species, the book presents a synthetic overview of livestock breeding as a whole. It gives considerable emphasis to genetics and animal breeding in the post-1960 period, the relationship between environmental and improvement breeding, and regulation of breeding as seen through pedigrees. In doing so, Made to Order shows how studying the ancient human practice of animal breeding can illuminate the ways in which human thinking, theorizing, and evolving characterize our interactions with all-natural processes.

Ideology of Purity challenges the assumption that animal breeding has served as a reliable model for eugenics through a direct comparison of the views of eugenicists with those of animal breeders. Eugenicists have cited animal breeding to justify their conceptions on human heredity and purity, misunderstanding the true meaning behind these principles and practices. Rather than accepting eugenic rhetoric at face value, this book examines how concepts like purity have been understood and applied differently in animal breeding and human eugenics. It explores how government policies have responded to both groups and aligned their demands. Historian Margaret E. Derry shows that the state promoted different forms of “purity” for animals and humans, and that the perceived parallels were more rhetorical than real. Through an analysis of topics such as nature versus nurture and the role of selective breeding, this book uncovers fundamental differences in goals, methods, and assumptions surrounding breeding. By drawing the conclusion that connections between eugenics and animal breeding were largely constructed through suggestive language rather than substantive similarity, Derry offers a new and critical perspective on the historical relationship between science, ideology, and policy.

In the spring and summer of 1938, a third-generation German Canadian took an unforgettable road trip in Europe. Franklin Wellington Wegenast drove through Austria, Italy, France, Luxembourg, and Germany. He stopped to talk to people along the way and offered rides to those requesting them. He listened to what his passengers had to say about their lives, the conditions they lived under, and their views on what was happening in Europe. Wegenast heard Hitler speak in Innsbruck, and so witnessed first-hand Nazi power as Austria's independence crumbled. In his journal he noted ""the sheer animal force in the cries of the crowd,"" and foresaw the ""collision course"" that was shaping up between the Germans who supported Hitler's ideology and the rest of the world. Wegenast was unable to publish the journal he kept on his journey, and at the time of his death in 1942 it was in an unorganized state. It is published here for the first time alongside commentary that puts the entries in the contexts of Wegenast's life experiences, the prevailing attitudes of the day, both in North America and Europe, and modern scholarship on Germany in the 1930s. The book includes correspondence Wegenast had with a young German for a few months after his return to Canada, correspondence that reveals even more clearly the intensity of his feelings and his fear for the future. Newly released government documents and diaries kept by Germans during the interwar period have meant a considerable outpouring in recent years of material on German sentiment in the 1930s. Wegenast's diaries and letters corroborate modern assessments of German thinking and add insightful commentary, providing an outsider/insider view on the brewing conflict.
