Paul dubbed the "Thomas Edison of music" (3)

Ross

I believe the answer is:

les

(Other definitions for les that I've seen before include "-- Dawson (late comedian)" , "Boy's name (abbr)" , "Short boy or girl" , "French article; name" , "-- Dawson, English comic" .)

I've seen this clue in the Universal.
