Les Paul, 94, The Granddaddy Of Every Rock ‘n’ Roll Guitarist

A “virtuoso guitarist and inventor whose solid-body electric guitar and recording studio innovations changed the course of 20th-century popular music, … Mr. Paul was a remarkable musician as well as a tireless tinkerer.” In addition to the electric guitar, “he built the first eight-track multitrack recorder. Each track could be recorded and altered separately, without affecting the others. The machine ushered in the modern recording era.”
