Fender’s Broadcaster pre-dates the Gibson Les Paul by a number of years. It was the first commercially successful solid-body electric guitar.
1949: Fender Broadcaster
1952: Gibson Les Paul
1954: Fender Stratocaster
Correct, however I believe that Les’ first experiments at making a solidbody guitar were in the 1920s or 1930s. And of course, that Rickenbacker “Pan” is often credited as the first commercial solid body electric guitar.
