George Beauchamp created and produced an electric Hawaiian lap steel guitarmade of a with a solid neck and body made from aluminum in 1931. Rickenbacker released the next year. Other companies, including Rickenbacker, Slingerland, and Vivi-Tone were able to market “electric Spanish” guitars (Spanish is the term used to describe the type of guitar that is played with a hand in the same way it is used in the present) at the end of the century. Jazz musician Charlie Christian used an electric Gibson ES-150, which was first released in 1936. It was a constant development over the following two decades and the the origins of electrified guitars remain unknown, as a lot of people came up with the same concept and began exploring independently and at the same time.
Les Paul is generally credited as “the creator of the electric guitar with a solid body.” The year was 1940. He contacted Gibson with a model constructed out of an 4″x4″ chunk of timber as well as the side of an Epiphone hollowbody, to demonstrate and was denied and then approached years later after the Gibson’s Ted McCarty felt the idea was worthy and, not coincidentally the idea was conceived after Fender began to market its single-pickup solidbody model called the Esquire in 1950. Under McCarty’s guidance, Gibson produced a Les Paul Signature model. McCarty was later able to in the creation of the Gibson Flying V, Explorer, and ES-335 models, as well as other. They both Fender along with Gibson model are among the top famous electric guitar styles; contemporary models have been modified in slight manners from their 1950s-era origins.
So…technically, George Beauchamp is the creator of the electric guitar that is solidbody along with Les Paul designed the prototypical guitar that is still in use today. In terms of who was the first to come in the direction of creating an electric guitar, the history isn’t clear.
