In three volumes, historian Jole Shackelford delineates the history of the study of biological rhythms – now widely known as chronobiology – from antiquity into the twentieth century. Perhaps the most well-known biological rhythm is the circadian rhythm, tied to the cycles of day and night and often referred to as the "body clock". But there are many other biological rhythms, and although scientists and the natural philosophers who preceded them have long known about them, only in the past thirty years have a handful of pioneering scientists begun to study such rhythms in plants and animals seriously. Tracing the intellectual and institutional development of biological rhythm studies, Shackelford offers a meaningful, evidence-based account of a field that today holds great promise for applications in agriculture, health care, and public health.
Volume 1 follows early biological observations and research, chiefly on plants.
Jole Shackelford is an associate professor in the Program for the History of Medicine, Department of Surgery, University of Minnesota Medical School in Minneapolis, and a part of the Graduate Program for the History of Science, Technology, and Medicine.
"As the first thorough scholarly treatment of an important subject, Jole Shackelford's study improves upon partisan accounts produced by scientists, who generally were trying to advance their own arguments rather than create a properly contextualized historical analysis. But these volumes do more than that: the stories told here raise many fundamental themes about the nature of science, about scientific controversies, and the way we think about organisms and their relationship to the environment. Shackelford provides an original analysis that will be an important starting point for all subsequent research on this topic. His command of this very technical subject is masterful, and the scientific context is developed in exceptional detail. His work also serves as an interesting survey of biological and medical science, over and above its value as a history of chronobiology."
