who is the father of occupational medicine in the United States

I can't find anything on the web. Here is my suggestion: At the school, check the encyclopedia under Public Medicine, and Occupational Health. If that fails, call the local Public Health Service and ask to speak to a nurse, and ask the question.

Please check my answer to your earlier question. Dr. Alicia Hamilton can be considered the mother of occupational medicine in the U.S.

amazing. I searched for about twenty min. Never considered a mom.
