Marie Lachapelle, French obstetrician (d. 1821)
Marie-Louise Lachapelle (1 January 1769 – 4 October 1821) was a French midwife, head of obstetrics at the Hôtel-Dieu, the oldest hospital in Paris. She published textbooks about women's bodies, gynecology, and obstetrics. She argued against forceps deliveries and wrote Pratique des accouchements, long a standard obstetric text, which promoted natural deliveries. Lachapelle is generally regarded as the mother of modern obstetrics.
