Arthur J. Vorwald to W. G. Hazard on X-Ray Readings and Kaylo Findings (1950)

A two-page letter of June 1, 1950, from Dr. Arthur J. Vorwald, director of the Saranac Laboratory, to W. G. Hazard of the Owens-Illinois Glass Company's Industrial Relations Division. Vorwald agreed to put Saranac's reading of chest X-rays of Owens-Illinois employees on a contract basis, at $4.00 per case. He reported that the Kaylo animal experiments were nearly done: Kaylo dust did not produce silicosis, but "It does produce the asbestotic type of reaction in the lungs and, therefore, we believe every precaution should be taken to minimize exposure of industrial employees."

What it shows

Vorwald wrote that the fee was kept low because of Saranac's "continued interest in problems relating to the inhalation of dust," and that studying such clinical material was "of tremendous help in our research program." He added that Kaylo produced only a mild effect on tuberculosis in infected animals. The copy is marked as plaintiff's exhibit P-241.

In Johns-Manville's index

Johns-Manville's legal department indexed the Motley 1,000 in 1984. Its index describes this document as follows:

Dr. A.J. Vorwald letter to W.G. Hazard, 6/1/50, responding to Hazard's letters of May 18 and April 3. Discusses the arrangement whereby Saranac Lab would read and interpret chest X-rays of Hazard's employees. Reports on results to date of the experimental investigation Saranac is conducting with respect to Kaylo. So far Saranac has found that Kaylo does produce an asbestotic type of reaction in the lungs, and therefore Saranac believes that every precaution should be taken to minimize exposure of "industrial employees."
