Well into the 19th century there were pronouncements from just about every branch of science and medicine that reading, writing, and thinking were dangerous for women. Articles in the Lancet declared that women's brains would burst and their uteruses atrophy if they engaged in any form of rigorous thinking. The famous physician J.D. Kellogg insisted that novel reading was the greatest cause of uterine disease among young women and urged parents to protect their daughters from the dreaded consequences of print.
