Daniel C. Braun to Hugh M. Jackson on Lung Cancer Literature for the Asbestos Textile Institute (1956)

A two-page letter of December 6, 1956, from Dr. Daniel C. Braun, medical director of the Industrial Hygiene Foundation, to Hugh M. Jackson, manager of Johns-Manville's Industrial Health Program. Braun sent material he had promised Jackson for a coming meeting about the Asbestos Textile Institute's study: summaries of published reports on lung cancer in asbestos workers, including the 1953 Isselbacher article, whose 20 collected cases included "two pipe insulators, one pipe coverer." He closed: "We will continue to send "ammunition" as we uncover it."

What it shows

Braun reported the Isselbacher article's conclusion "that asbestos is associated with bronchogenic carcinoma in 13.8% of the cases cited in the literature," Richard Doll's 1955 finding of 18 lung cancers among 105 autopsies at a large asbestos works, and a 1949 paper predicting that compensation claims would grow. He hoped the material would help Jackson "in enlightening the representatives of the textile industry." The letter shows that by late 1956 Johns-Manville's health manager was being briefed on the published evidence linking asbestos to lung cancer, including cases among insulation workers.
