Details

Irving J. Selikoff (1915–1992) was a chest physician and researcher who had often been described as America’s foremost medical expert on asbestos related diseases between the 1960s and the early 1990s.

Through a lung clinic that he operated in New Jersey, Selikoff collected data from a sample of around 1200 insulation workers in metropolitan New York in 1963.
