William Wellesley Mapleson 1926-

This son of an insurance clerk was born in London in 1926. He attended Durham university were he studied physics. He successfully applied for a position as lecturer at the Welsh National School of Medicine to which to this day he is still employed as Professor.

His place in the history of anaesthesia and surgery is because of his work on the major breathing circuits of the day to eliminate re-breathing. His naming of those circuits were A,B,C,D,E and F

I was once told a story about an anaesthetist who was being interviewed by a panel for the RCA and the interviewee was asked what he knew about Mapleson, he replied with knowledge of his achievements but said he thinks he is now dead! to which a voice at the rear of the panel said

"No I'm Not!"

So, at the time of writing this he is still alive and for quite a few years more we hope.
