The Chemical Industry's Attack on Historians 

We think it important to put this controversy in a broader context. During the past decade or so historians have been drawn into the courtroom as expert witnesses in cases involving workers and consumers harmed by a variety of products including tobacco, lead, asbestos, silica and most immediately plastics. This issue has become widely discussed among historians of medicine but has so far escaped attention within the broader community of historians.[2] Of most significance for the historians of medicine is that Kenneth Ludmerer, past president of the American Association for the History of Medicine, Peter English, professor of medicine and history at Duke, Robert Hudson at the University of Kansas and John Burnham at Ohio State, among others, have worked for or testified on behalf of tobacco companies, lead companies and other industries that have been the defendants in lawsuits. In addition, historians such as ourselves, Robert Proctor at Stanford and Allan Brandt at Harvard have testified or worked with workers injured or diseased by their job, children damaged from lead and individuals hurt by tobacco, as well as various cities, states, and the federal government in suits brought against tobacco, lead, silica, and now the chemical industry.

It appears that the legal strategies of the law firms defending the various industries have been more or less the same, following a common pattern and a common rationale. In what historian Robert Proctor has called agnatology, industry has created a new "science" for the creation of doubt and ignorance about its actions in the past and historians have played a significant, if duplicitous role.[3]

In brief, as Robert Proctor has stated in a number of oral presentations and editorials with regard to the tobacco industry, historical experts testifying for industries have adopted a few basic techniques to undermine the historical data indicating knowledge of danger. In general, they have argued that:

* Whatever the evidence of knowledge within industries of the dangers of a product existed in the past, there was insufficient information available for there to be definitive proof of real danger.

* Therefore, there was always a need for more research before doubt could be eliminated and those who questioned that a material was dangerous meant that there was a "controversy" about whether or not it was.

* Causation is extremely difficult to prove and requires years, if not decades, of careful experimentation and observation before "controversy" about the sources of disease could cease.

* Hence, without certainty, and in the context of any on-going controversy about the danger of a product or substance, there was little or no obligation on the part of industries to act to remove their product from the market or to lower exposures to toxic materials within the factory. [4] . . .

[3] Robert Proctor has been engaged in the path-breaking research into historians' role in the tobacco cases and has coined this term in oral presentations. See, Robert N. Proctor, "Should Medical Historians be Working for the Tobacco Industry?" Lancet 363 (Apr 10, 2004), 1174-5.
