William Flockhart, L.R.C.S.E. (1808 – 1871) was a Scottish chemist, a pharmacist who provided chloroform to Doctor (later Sir) James Young Simpson for his anaesthesia experiment at 52 Queen Street, Edinburgh on 4 November 1847. This was the first use of this chemical on humans when Simpson tried it on himself and a few friends, and then used it for pain relief in obstetrics, and surgery. This changed medical practice for over a century, according to the British Medical Journal.
