Rav Aharon Halevi was born in Gerona in 1235, and studied under his father and brother, as well as [[Ramban]]. He published critical notes on [[Rashba]]'s ''[[Torat HaBayit]]''[[, which he entitled ''[[Bedek HaBayit]]''. He also wrote a commentary on the Talmud, select parts of which have been published. There are those who believe that he is the author of the ''[[Sefer HaChinuch]]'', although this claim has been rejected by many. [[Ritva]] was one of his students.
