Roy Claxton Acuff (September 15, 1903 – November 23, 1992) was an American country music singer, fiddler, and promoter. Known as the King of Country Music, Acuff is often credited with moving the genre from its early string band and "hoedown" format to the star singer-based format that helped make it internationally successful.
Acuff began his music career in the 1930s, and gained regional fame as the singer and fiddler for his group, the Smoky Mountain Boys. He joined the Grand Ole Opry in 1938, and although his popularity as a musician waned in the late 1940s, he remained one of the Opry's key figures and promoters for nearly four decades. In 1942, Acuff co-founded the first major Nashville-based country music publishing company—Acuff-Rose Music—which signed acts such as Hank Williams, Roy Orbison, and The Everly Brothers. In 1962, Acuff became the first living person inducted into the Country Music Hall of Fame
