Les Paul

Mr. Paul was a remarkable musician as well as a tireless tinkerer. He played guitar with leading prewar jazz and pop musicians from Louis Armstrong to Bing Crosby. In the 1930s he began experimenting with guitar amplification, and by 1941 he had built what was probably the first solid-body electric guitar, although there are other claimants. With his electric guitar and the vocals of his wife, Mary Ford, he used overdubbing, multitrack recording and new electronic effects to create a string of hits in the 1950s.

Mr. Paul’s style encompassed the twang of country music, the harmonic richness of jazz and, later, the bite of rock ’n’ roll. For all his technological impact, though, he remained a down-home performer whose main goal, he often said, was to make people happy.

And he was still playing every Monday night at Iridium in New York City.
