Justus von Liebig
The Chemical Gatekeeper

"...Brock portrays a living and breathing human being, and not the usual plaster figure of the hagiographical literature; we see especially a man who is thoroughly engaged in the political and commerical life of his era. No one has hitherto succeeded in depicting so well this multifaceted Liebig, and Brock's success in doing so constitutes a signal triumph of this remarkable and admirable book." The Journal of the History of Medicine and Allied Sciences

"...Brock's work brings to the English-speaking world a long-awaited biography of one of the most important figures in the history of chemistry. In what is perhaps the most significant lesson that emerges from this study, Brock shows how Liebig was a 'public scientist,' recognizing and embracing the civic importance of his science in the modern world." Science

"Constructing a full biography of a scientist has long presented problems for historians on how to meld the science with the life without ignoring one at the expense of the other, or without making an artifical division between them. Brock has balanced these needs well, creating a picture of Liebig and his influence that can be enthusiastically recommended to chemists and historians alike." Bulletin of the History of Chemistry

"William Brock has given us a definitive biography...of a very complex person. Demonstrating an exceptional command of primary documents, recent secondary literature, and standard hagiography, Brock has painted a thematically organized portrait that explains the many dimensions of Liebig's life and work. This is a great book. A `must-read' for historians of nineteenth-century science, it will engage and enlighten anyone interested in the role science plays in modern Western civilization. There's nothing fancy: no psychoanalysis, no postmodern deconstruction, no philosophical webs of metascience, no heavy-handed sociological categories. It's just good scholarship and an enjoyable narrative. Brock focuses on a significant historical figure, clearly explains the changes in science and society that surrounded that figure, and interprets those changes in a way that is meaningful for general readers. As a solid and comprehensive biography of Liebig, it will long endure." Isis

"...carefully selected illustrations and tables provide a good impression of Liebig's times...Brock has written a very sound biography, and he has succeeded in giving a portrait of Liebig's British connections and the effects of his works and performance in Britain. Considering the chapters on farming, food chemistry, and the chemistry of sewage, this book will also be of interest for the historian of technology." Technology and Culture

"Brock's biography is informative and wide ranging...." Agricultural History

"...interesing, useful biography." American Historical Review
