Les Paul (June 9, 1915 – August 13, 2009)

Rest in peace to Les Paul, one of the most important figures in not only the recording industry, but music as a whole.  

He is best known as a pioneer of the solid body electric guitar.  Gibson Guitar Corporation even went so far as to develop a guitar with him that shared his namesake.  Less publicized are his innovations in recording technology including overdubbing, delay effects, phasing effects, and multi-track recording.
