Les Paul exhibit arrives at Rock & Roll Hall of Fame

Why he matters: Paul's prototype for a solid-body electric guitar in the 1940s served as the inspiration for the Gibson Les Paul — arguably the most iconic guitar in rock history — that debuted in 1952.

• Paul is also credited with helping pioneer several recording techniques, including delay effects, phasing, and overdubbing.

The intrigue: "Les Paul Thru the Lens" features 24 black-and-white photographs from Paul's life, including childhood and rare family photos, performance shots, and images of his early inventions.

Flashback: Paul used to have an exhibit in the Rock Hall, honoring the electric guitar models he inspired.

• Yes, but: It was replaced by the museum's interactive "The Garage" exhibit in 2019.

If you go: The exhibit is in the museum's Roots Gallery on the bottom floor.
