Anna Baetjer was born and reared in Baltimore. She received her B.A. from Wellesley College in 1920, and her D.Sc. from the Johns Hopkins University School of Hygiene and Public Health in 1924. After earning her doctoral degree, she joined the faculty of the school of hygiene and public health. Her interest in occupational health began with studies in the 1920s on the effects of high temperature and humidity on workers. As early as the 1950s, she called for increased studies of air pollution, and in the early 1960s she foresaw the coming concern over complex chemicals in the environment. In 1963, she established at Johns Hopkins one of the first research and training programs in environmental toxicology in the United States. Baetjer gained a worldwide reputation for her research on the effects of toxic substances and assisted the World Health Organization in setting recommended worldwide standards for chromium exposure. She taught public health specialists from all over the world and was the author of many scientific papers and books.
