Rabbi Aharon HaLevi was a student of Ramban and a descendant of R. Zerachiah HaLevi (the Ba'al HaMaor). He was involved in the talmudic discussions of the Spanish rabbis of his time. This led him to write a gloss on Rashba's Torat HaBayit called Bedek HaBayit and commentaries on several volumes of the Talmud. Most scholars deny the claim that he was the anonymous author of Sefer HaChinukh.
