George Delmetia Beauchamp (//; March 18, 1899 – March 30, 1941) was an American inventor of musical instruments. He is known for designing the first electrically amplified stringed instrument to be marketed commercially. He was also a founder of National Stringed Instrument Corporation and Rickenbacker (originally Rickenbacher) guitars.
He was born in Coleman County, Texas on March 18, 1899. Beauchamp performed in vaudeville, playing the violin and the lap steel guitar, before he settled in Los Angeles, California. During the 1920s, he experimented with the creation of electric lap steel guitars, electric guitars, electric bass guitars, electric violins, and instrument amplifiers. In 1931, he joined with Paul Barth and Adolph Rickenbacker to form the Ro-Pat-In Corporation to produce and sell electrified string instruments. The most notable of these, the Rickenbacher A-22 (and A-25) lapsteel guitar – known as the "frying pan" – is widely regarded as the first mass-produced electric guitar. Production of the instrument began in 1932. In 1937, Beauchamp secured a United States patent for his version of the electric guitar.
