Lester William Polsfuss, known as Les Paul (June 9, 1915 – August 13, 2009) was a musician and innovator. He was a pioneer in the development of the solid-body electric guitar which “made the sound of rock and roll possible.”[1] He is credited with many recording innovations, including overdubbing (also known as sound on sound),[2] delay effects such as tape delay, phasing effects, and multitrack recording.[3]
His innovative talents extended into his playing style, including licks, trills, chording sequences, fretting techniques and timing, which set him apart from his contemporaries and inspired many of the guitarists of the present day.[4][5][6][7] He recorded with his wife Mary Ford in the 1950s and they sold millions of hit records.
Among his many honors, Les Paul is one of a handful of artists with a permanent, stand-alone exhibit in the Rock and Roll Hall of Fame. [8] He is prominently named by the music museum on their website as an “architect” and a “key inductee” along with Sam Phillips and Alan Freed.
