George Beauchamp created the “Frying Pan” in 1931, and it was subsequently manufactured by Rickenbacker Electro. The instrument Rickenbacker Electro A-22 earned its nickname because its circular body and long neck make it resemble a frying pan.
It was designed to capitalize on the popularity of Hawaiian music in the 1930s. The instrument was made of cast aluminum, and featured a pair of horseshoe magnets that arched over the strings.
Beauchamp and machinist Adolph Rickenbacker began selling the guitar in 1932, but Beauchamp was not awarded a patent for his idea until 1937, which allowed other guitar companies to produce electric guitars in the same period.
