Frau Bergmann is the mother of Wendla in both musical and play. She refuses to give Wendla lessons about puberty and sex, leaving her daughter ignorant in both versions. After her discovery of Wendla's pregnancy, she denies any responsibility and forces her daughter to get an abortion, in which results into a fatal and botched one.
Frau Bergmann is a doting mother to her daughters and her grandchildren. Yet, she still pictures Wendla as a child, not a young woman. This causes her to not entrust the truth of reproduction with Wendla, leaving her naive and uneducated. She is an extremely shallowed-mind woman (along with the majority of the adults) and could not wrap her mind around Wendla's becoming a mother at such a young age and the scandal of having a child out of wedlock, too. Her decision to force Wendla into an abortion turns into an unsafe and ill-fated one, and covers up her death with anemia on her grave.
