Who was the air traffic controller voice?
You are thinking of a reference to Charles ("Chuck") Yeager.  He was certainly not an air traffic controller, but there has definitely been a statement published in print saying that his manner of speaking over the radio has been the model that has been copied numerous other times (in movies and by other pilots in real life, as I recall the statement saying.) 

The reference was in the book "The Right Stuff"-- pages 33-34 and possibly a few more (not shown) in this ebook edition.
