## Early history

At the end of 1931, Beauchamp, Barth, Rickenbacher and several other individuals banded together and formed the Ro-Pat-In Corporation (elektRO-PATent-INstruments) to manufacture and distribute electrically amplified musical instruments, with an emphasis on their newly developed A-25 Hawaiian Guitar, often referred to as the "fry-pan" lap-steel electric guitar as well as an Electric Spanish (standard) model and companion amplifiers. In the summer of 1932, Ro-Pat-In began to manufacture cast aluminum production versions of the Fry-Pan as well as a lesser number of standard Spanish Electrics also known as "Electro-Spanish" models, built from wooden bodies similar to those made in Chicago for the National Company. These instruments constitute the origin of the electric guitar by virtue of their string-driven electro-magnetic pick-ups. In 1933 the Ro-Pat-In company's name was changed to Electro String Instrument Corporation and its instruments labeled simply as "Electro". In 1934 the name of Rickenbacker" was added in honor of the company's principal partner, Adolph Rickenbacher.
