The American Environmental Health Foundation, in Dallas, was founded in 1975 by William J. Rea of the Environmental Health Center to promote environmental medicine, a branch of medical science dedicated to the study and treatment of adverse environmental effects. It was first named the Human Ecology Research Foundation of the Southwest. The foundation is funded by private donations and endowments and an international medical conference, the International Symposium on Man and His Environment in Health and Disease. It had an office staff of four in 1992. Services have included publications on environmentally triggered diseases, products designed for sensitive individuals, and referral and information services. The foundation also funds research projects to help physicians diagnose and treat environmentally induced illness and publishes semiannual and quarterly newsletters.
