James Young Simpson introduces chloroform anaesthesia in an obstetric case

Background. Sir James Young Simpson was a significant figure in medicine, appointed physician to the Queen in Scotland by 1847. He was the first physician to demonstrate chloroform's anaesthetic properties in humans. Although Robert Glover had described these properties in animals in 1842, Simpson helped popularize the drug for medical use, particularly in obstetrics.

Prior Work and Controversy. Dr Robert Mortimer Glover described chloroform's anaesthetic properties in animals in 1842 but feared using it on humans. Simpson's publications in 1847 echoed Glover's work, leading to accusations of plagiarism. Glover presented his findings in 1847, identifying anaesthetizing compounds as poisonous substances, while Simpson claimed discovery in humans.

Obstetric Application. Simpson's most significant contribution was introducing anaesthesia to childbirth. He tested chemicals with assistants in his dining room. On 4 November 1847, he and friends tried chloroform obtained from pharmacist William Flockhart. The first child delivered under chloroform was baptised Wilhelmina, though nicknamed 'Anaesthesia' by Simpson.
