who was the teacher of Siddhartha's?​

Answer 1

Answer:

Alara Kalama

After Gautama became an ascetic, he went to Alara Kalama, who was a teacher that taught a kind of early meditation at Vessali. Alara taught Gautama Buddha meditation, especially a dhyānic state called the "sphere of nothingness" (Pali: ākiñcaññāyatana).
