Les Paul (Lester William Polsfuss)
(June 9, 1915 – August 12, 2009)

Paul is credited with many recording innovations. His early
experiments with overdubbing (also known as sound on
sound delay) effects such as tape delay, phasing, and
multitrack recording were among the first to attract
widespread attention.

His licks, trills, chording sequences, fretting techniques,
and timing set him apart from his contemporaries and
inspired many guitarists of the present day. Paul is the
only inductee in both the Rock and Roll Hall of Fame
and the National Inventors Hall of Fame.

Clapton is widely regarded as one of the most important and
influential guitarists of all time. Clapton ranked second in Rolling
Stone‘s list of the "100 Greatest Guitarists of All Tim”" and fourth
in Gibson‘s "Top 50 Guitarists of All Time". He was also named
number five in Time magazine’s list of "The 10 Best Electric
Guitar Players" in 2009.

(1960), brought international fame to the group, and is

Les Paul (1915-2009) and Mary Ford (1924-1977)  were a popular
1950s husband-and-wife musical duo who performed and recorded during 1945–1963. The couple were introduced to each other by
Gene Autry in 1945 and were married on December 31, 1949.

Paul and Ford are famous for creating a makeshift recording studio
in their garage. In that studio, they used multitrack recording to
record many of their big hits.

Ford and Paul were music superstars during the first half of the
1950s, putting out 28 hits for Capitol Records between 1950 and
1957, including "Tiger Rag", "Vaya con Dios" (11 weeks at No. 1), "Mockin’ Bird Hill" (top 10), "How High the Moon" (nine weeks at
No. 1), "Bye Bye Blues" and "The World Is Waiting for the Sunrise".
