American toxicologist and public health researcher (born 1908)

Mary Amdur

Mary Ochsenhirt Amdur was an American toxicologist and public health researcher who worked primarily on pollution. She was charged with studying the effects of the 1948 Donora smog, specifically looking into the effects of inhaling sulfuric acid by experimenting on guinea pigs. Her findings on the respiratory effects related to sulfuric acid led to her being threatened, her funding being pulled, and her losing her job at the Harvard School of Public Health in 1953. Undeterred, she carried on her research in a different role at Harvard, and subsequently at MIT and New York University.
