H. M. Jackson to C. L. Sheckler on X-Ray Films of Talcosis (1956)

A one-page memo of November 26, 1956, from H. M. Jackson at J-M headquarters to C. L. Sheckler at the Manville plant, following Sheckler's phone call of November 15. Dr. L. J. Bristol could not supply X-ray films of talcosis (lung disease from talc dust), but Dr. I. R. Tabershaw, director of the Division of Industrial Hygiene of the New York State Department of Labor, had some and would send them to Dr. D. T. DuBow at Manville. A handwritten note from Sheckler asks DuBow to send the films to a Dr. J. Smith at the New Jersey state sanatorium in Glen Gardner, to be reviewed "prior to his testimony."
