THE RAPPER THAT WAS DISCOVER BY DRE WAS EMINEM "THE BEAST " SLIM SHADY , marshal mathers.
it is probably Eminem, Lil Wayne, or Dr. Dre
Eminem
Dr. Dre signed Eminem to his record label, Aftermath.
Between Eminem and Dr. Dre, nether are the better rapper, Em attributes his success to Dre but I personally do not think that one is better than the other.
Dr. Dre was Eminem's mentor
Proof was Eminem's friend. Dr. Dre is Eminem's mentor (and friend, too though) So Eminem would likely admire Dre most for rap.
Dr. Dre
Dr dre is a rappre and a record producer. shady is eminem himself
dr dre and proof
Dr. Dre is currently the richest rapper in the world. Until May of 2014, Diddy was the richest rapper. He was overtaken by Dr. Dre in part due to sales of Beats by Dre.
Eazy - E founded Dr. Dre. Dr. Dre founded Eminem. If it wasn't for the God-father of Gangsta Rap/Hip-Hop, Eazy muthaphukkin E, (rip) Nobody would have a clue who Dr. Dre or Eminem is.
