Aaron ibn Sargado
Aaron ibn Sargado or Aaron ben R. Joseph ha-Kohen (Hebrew: אהרן הכהן בן יוסף - כלף סרג'דו)) was a tenth-century AD gaon (Jewish religious leader) in Pumbedita, Babylonia. He was a son of Joseph ha-Kohen.
Rav Shrira continues to note that Rabbi Ahron HaKohen was not of a family of scholars, but of wealthy merchants, he was elevated to the gaonate (presidency of a rabbinical academy) through the influence of his family. Caleb ibn Sargado, the determined opponent of Saadia, who spent 60,000 zuzim in order to bring about the deposition of the gaon of Sura, was probably identical with Aaron, as Harkavy has shown (see Seder 'Olam Zuṭṭa in "Anecdota Oxoniensia," ii. 83).
Four of Sargado's legal decisions on religious problems are preserved, and are printed in the collection, "Ḥemdah Genuza," Nos. 37-40. One of these, it appears, was the answer to an inquiry from Kairouan.
