Atlantic Recording Corporation (simply known as Atlantic Records) is an American record label founded in October 1947 by Ahmet Ertegün and Herb Abramson. Over its first 20 years of operation, Atlantic Records earned a reputation as one of the most important American recording labels, specializing in jazz, R&B and soul recordings by African-American musicians including Aretha Franklin, Ray Charles, Wilson Pickett, Sam and Dave, Ruth Brown and Otis Redding, a position greatly enhanced by its distribution deal with Stax Records. In 1967, Atlantic Records became a wholly owned subsidiary of Warner Bros.-Seven Arts, now the Warner Music Group, and expanded into rock and pop music with releases by bands such as Led Zeppelin and Yes. In 2004, Atlantic Records and its sister label Elektra Records merged into Atlantic Records Group. Craig Kallman is currently the chairman of Atlantic Records. Ahmet Ertegün served as founding chairman until his death on December 14, 2006 at age 83. In 1944, brothers Nesuhi and Ahmet Ertegun elected to remain in the United States when their mother and sister returned to Turkey, following the death of their father Munir Ertegun, who had been the first Turkish Ambassador to the United States. The brothers had become ardent fans of jazz and rhythm & blues music, amassing a collection of over 15,000 78 RPM records. Ahmet ostensibly stayed on in Washington to undertake post-graduate music studies at Georgetown University but immersed himself in the Washington music scene and decided to enter the record business, then enjoying a resurgence after wartime restrictions on the shellac used in manufacture. He convinced the family dentist, Dr Vahdi Sabit, to invest $10,000 and recruited Herb Abramson, a dentistry student.
