Bauer, leader in baby-tooth study, 82

Walter C. Bauer, M.D., a retired professor of pathology at the School of Medicine, died Saturday, Feb. 2, at Barnes-Jewish Hospital after a brief illness. He was 82.

Bauer joined the School of Medicine faculty in 1958 as an instructor in surgical pathology and pathology and retired in 1989.

In the 1950s and ’60s, Bauer was a leader in the St. Louis Baby Tooth Survey, which studied nearly 300,000 baby teeth in a search for evidence of fallout from nuclear bomb tests. The results led to a ban on above-ground nuclear weapons testing.
