Sir James Young Simpson, 1st Baronet (7 June 1811 – 6 May 1870) was a Scottish obstetrician and an important figure in the history of medicine. Simpson discovered the anaesthetic properties of chloroform and successfully introduced it for general medical use. James Simpson was born in Bathgate, West Lothian, the youngest of seven children. James received his initial education at the local school, but because of his obvious abilities his father and brothers (his mother died when he was 9) together paid for a college education and he entered the University of Edinburgh when he was 14 years old. Simpson completed his final examination at the age of 18 but, as he was so young, had to wait two years before he got his license to practice medicine. He became a Licentiate in 1830 before graduating in 1832 with an MD. He was appointed Professor of Midwifery (which would now be called Obstetrics) at the University of Edinburgh and physician to Queen Victoria.
At the age of 28 he was appointed to the Chair of Medicine and Midwifery at the University of Edinburgh. He improved the design of obstetric forceps that to this day are known in obstetric circles as "Simpson's Forceps" and, like Semmelweis, fought against the contagion of puerperal sepsis. His most noted contribution was the introduction of anesthesia to childbirth. Simpson's intellectual interests ranged from archaeology to an almost taboo subject at the time: hermaphroditism. He was a very early advocate of the use of midwives in the hospital environment. Many prominent women also consulted him for their gynaecological problems.
