Who help eminem become a rapper?

Answer 1

Eminem (Marshall Bruce Mathers III) was built on his own ground. He was quick to get famous after his two first albums, his first won him a Grammy for best rap album and his second was the fastest selling hip-hop album in history, The slim shady LP and The Marshall Mathers LP.

No one helped him at all.

Answer 2

it is said he was discovered, signed and mentored by Dr dre.

so i guess he would have been the one who helped him become a rapper.
