|Simpson invites friends to his house to experiment with Chloroform's anaesthetic properties. Simpson and his guests Dr. Matthew Duncan and Dr. George Keith inhaled chloroform vapors and fell unconscious. Eleven days later, Simpson successfully demonstrated Chloroform's anaesthetic properties at the Royal Infirmery of Edinburgh. 2
|Queen Victoria accepted chloroform as anesthesia during the delivery of Prince Leopold, her seventh child. Because of this, the practice of using chloroform or any anesthesia during childbirth became significantly more acceptable. Revealing the thinking of the time, in response to Queen Victoria's decision, the Lancet said in May 1853 "In no case could it be justifiable to administer chloroform in a perfectly ordinary labour." 3
|The use of anesthesia (chloroform, ether, or nitrous oxide) becomes generally accepted during surgery and childbirth.
