David Marrack

Bellaire | Physician

Dr. Marrack was a physician in Houston, where he worked at academic institutions such as the Baylor College of Medicine and the University of Texas School of Public Health, as well as at public clinics. His research and clinical experience, along with his training in pathology, helped in his advocacy on human health’s environmental factors. Dr. Marrack was particularly active in working to lower the impact of air pollution on health, entering comments on toxic constituents, fine particulate matter, incineration emissions, upset releases, and vehicular pollution. He was also a birder, and through that interest, a co-founder of the Houston Audubon Society, and one of the partners in the acquisition of the Attwater Prairie Chicken Refuge by the Nature Conservancy of Texas (later transferred to the U.S. Fish and Wildlife Service).
