I want to reiterate my recommendation of "Saga of Telegraphy" by Ralph Graham who worked for New York Times as a wire telegrapher. It is a priceless recording without peer. 

I believe every Morse operator should listen to it at least once

It reenacts events in Wire Morse history using the Mother tongue, American Morse, then events in Radio Morse using International Morse.

J. Ralph Graham, W8KPE, was a first-class landline and radio telegrapher.
