James Young Simpson was one of the first obstetricians to administer anesthesia during childbirth in nineteenth century Scotland. Before his work in the 1800s, physicians had few ways to reduce the pain of childbirth. Simpson experimented with the use of ether and chloroform, both gaseous chemicals, to temporarily relieve pain. He found that those chemicals both successfully inhibited the pain women felt during childbirth and pain during other surgeries. Patients under the influence of chloroform fell asleep and were unaware of the intense pain of childbirth. Simpson’s work was not popular for a variety of reasons, and the major claim against his practice being that pregnant women should not receive a form of pain relief during labor and childbirth. Against common beliefs at the time, Simpson advocated in favor of using anesthetics for pain-free labor, which later became the standard for surgical procedures and childbirth.
