Is the maternity unit I worked at, overlooking the Meadows. 

James Simpson was young obstetrician who
experimented with gases on himself, trying to find something effective in childbirth.  He was the first to try chloroform in childbirth (but had to
retranslate Genesis first in order to convince the public that it was not blasphemous to alleviate a woman's pain).

PS Chloroform cannot be used to overpower someone, the way it is always used in  films; it takes a period of prolonged deep breathing to become effective.
