Historical Aspects of Occupational Asthma

Editors’ Note: In the first and second editions of Asthma in the Workplace, this chapter was coauthored by Drs. Jack Pepys and I. Leonard Bernstein. Dr. Pepys’ contribution was the ‘‘Introduction’’ through the section entitled ‘‘Simulated Occupational Provocation Tests,’’ which the editors decided to retain in toto for this issue. This section includes a review of some of Dr. Pepys’ key contributions to occupational asthma and therefore reinforces the dedication of this book to him. The remaining sections of the chapter, beginning with the section ‘‘Current Status of Occupational Asthma,’’ have been revised by I. Leonard Bernstein.
