Anna Medora Baetjer (July 7, 1899 – February 21, 1984) was an American physiologist and toxicologist, known for her research into the health effects of industrial work on women and for her discovery of the carcinogenic properties of chromium.
[3] Prompted by concerns of increased lead poisoning among Baltimore children during the summer months, Baetjer conducted a study that demonstrated a link between high temperature and humidity and slower toxin excretion.
[2] In 1944, the War Department issued a set of policies on pregnancy and civilian workers based on Baetjer's recommendations.
[4] During the 1940s, Baetjer began to investigate the incidence of cancer in a Baltimore chromium plant and waste pile.
[1] In 1974, she demonstrated that exposure to inorganic arsenic led to increased cancer risk for workers at pesticide plants.
[1] In 1985, Johns Hopkins University established the Anna M. Baetjer Chair in Environmental Health Sciences.
