Rabbeinu Yona
From Wikinoah English
Born in the late 12th century in Gerona, Spain, Rabbeinu Yonah is best known for his Sha'arei Teshuva, a work on ethics and repentance. He also wrote a commentary on Rif's Sefer HaHalchot, although only the section on tractate Berachot survives. He wrote several smaller works, including a commentary on Avot. He studied under Rav Shlomo Montpelier, and he taught, among others, Rashba.
