University of Wisconsin School of Medicine and Public Health alumni

Mary Elizabeth Tidball (née Peters; October 15, 1929 – February 3, 2014) was an American physiologist. She was an advocate for women in academia and STEM and a supporter of women's colleges. Tidball was a longtime faculty member at George Washington University School of Medicine & Health Sciences (GW) where she became the institution's first woman appointed professor of physiology. Her research in the 1960s on the career outcomes of graduates from women's colleges versus those from coeducational institutions sparked discussions that continued for decades. Tidball was the first female president of the Cathedral Choral Society where she sang for almost fifty years.
