Which rapper founded Aftermath Entertainment in 1996?

The rapper who founded Aftermath Entertainment in 1996 was Dr. Dre. The label emerged after Andre Young left Death Row Records and established a new imprint through Interscope Records.

Aftermath began as a boutique label intended to focus on a small number of carefully developed artists and releases. Its first major project was the compilation album Dr. Dre Presents the Aftermath, released in November 1996. Although that early period was commercially uneven, the label later became one of hip-hop’s most influential homes.

A turning point came when Dr. Dre signed Eminem in 1998. Eminem’s The Slim Shady LP, released in 1999, became a major commercial success, followed later that year by Dr. Dre’s 2001. Aftermath subsequently became associated with artists including 50 Cent, Kendrick Lamar and Anderson .Paak.

The question asks who founded the label, not who distributed or later popularized it. Aftermath has operated through Interscope and is part of the Universal Music Group structure, but those companies are not its founder.
