I recall reading somewhere that the 'Air traffic controller' voice (you've heard it on TV on many occasions) started with one specific person and his mannerisms have been copied by many air traffic controllers since, particularly in the US. The article mentioned his name but I can't find the article and can't remember his name.
What was the name of this chap?
Edit: I think that I read this in Fate Is The Hunter, an autobiography of a pilot working in the '30s to '60s. Unfortunately I don't still have my copy so I can't look it up.
