The Power of Exercise and the Exercise of Power: The Harvard Fatigue Laboratory, Distance Running, and the Disappearance of Work, 1919-1947.

In the early twentieth century, fatigue research marked an area of conflicting scientific, industrial, and cultural understandings of working bodies. These different understandings of the working body marked a key site of political conflict during the growth of industrial capitalism. Many fatigue researchers understood fatigue to be a physiological fact and allied themselves with Progressive-era reformers in urging industrial regulation. Opposed to these researchers were advocates of Taylorism and scientific management, who held that fatigue was a mental event and that productivity could be perpetually increased through managerial efficiency. Histories of this conflict typically cease with the end of the First World War, when it is assumed that industrial fatigue research withered away. This article extends the history of fatigue research through examining the activities of the Harvard Fatigue Laboratory in the 1920s and 1930s. The Laboratory developed sophisticated biochemical techniques to study the blood of exercising individuals. In particular, it found that exercising individuals could attain a biochemically "steady state," or equilibrium, and extrapolated from this to assert that fatigue was psychological, not physiological, in nature. In contrast to Progressive-era research, the Laboratory reached this conclusion through laboratory examination, not of industrial workers, but of Laboratory staff members and champion marathon runners. The translation of laboratory research to industrial settings, and the eventual erasure of physiological fatigue from discussions of labor, was a complex function of institutional settings, scientific innovation, and the cultural meanings of work and sport.

Following cancer viruses through the laboratory, clinic, and society.

These essays in this special issue follow cancer viruses as a means of better understanding the history of biomedicine. Spanning the worlds of chronic and infectious disease research, the history of cancer viruses touches upon an enormous diversity of settings and scientific disciplines. Cancer viruses appeared during the twentieth century as vaccine targets, vaccine contaminants, laboratory anomalies, and tools for molecular biology. Rather than picking one discipline or setting to privilege above others, this issue suggests what can be learned, not only about cancer viruses but also about the character of modern biomedicine, from following these viruses through their different historical trajectories.

Managing the future: the Special Virus Leukemia Program and the acceleration of biomedical research.

After the end of the Second World War, cancer virus research experienced a remarkable revival, culminating in the creation in 1964 of the United States National Cancer Institute's Special Virus Leukemia Program (SVLP), an ambitious program of directed biomedical research to accelerate the development of a leukemia vaccine. Studies of cancer viruses soon became the second most highly funded area of research at the Institute, and by far the most generously funded area of biological research. Remarkably, this vast infrastructure for cancer vaccine production came into being before a human leukemia virus was shown to exist. The origins of the SVLP were rooted in as much as shifts in American society as laboratory science. The revival of cancer virus studies was a function of the success advocates and administrators achieved in associating cancer viruses with campaigns against childhood diseases such as polio and leukemia. To address the urgency borne of this new association, the SVLP's architects sought to lessen the power of peer review in favor of centralized Cold War management methods, fashioning viruses as "administrative objects" in order to accelerate the tempo of biomedical research and discovery.

The fate of a progressive science: the Harvard Fatigue Laboratory, athletes, the science of work and the politics of reform.

In the early twentieth century, fatigue research marked a site of conflicting scientific, industrial, and cultural understandings of working bodies. Many fatigue researchers understood fatigue to be a physiological fact and allied themselves with Progressive-era reformers in urging industrial regulation. Reformers clashed with advocates of Taylorism, who held that productivity could be perpetually increased through managerial efficiency. Histories of this conflict typically cease with the end of the First World War. I examine the work of the Harvard Fatigue Laboratory in the 1920s and 1930s to explore the impact that the introduction of biochemical methods had on the relationship between science and reform. The Laboratory developed sophisticated techniques to study the blood of exercising individuals. In particular, it found that exercising individuals could attain a biochemically "steady state," or equilibrium, and extrapolated from this to assert that fatigue was psychological, not physiological, in nature. In contrast to Progressive-era research, the Laboratory reached this conclusion through laboratory examination, not of workers, but of Laboratory staff members and champion marathon runners. I present the Laboratory's institutional history, scientific work, and finally how common cultural understandings of athletes and work lent plausibility to its efforts to make authoritative statements about industrial conditions.

Interests and instrument: a micro-history of object Wh.3469 (X-ray powder diffraction camera, ca. 1940).

This paper presents a micro-history of an object in the collection of the Whipple Museum of the History of Science (accession no. Wh.3469), with an emphasis on how Wh.3469 reflects a hybrid of two different interwar British X-ray crystallographic communities, namely those based in WL Bragg's physics laboratory at the Victoria University of Manchester and the Crystallographic Laboratory at the University of Cambridge. It explores connections between Wh.3469's final design and construction and the different interests each community had in X-ray crystallography.
