Jacob of Nehar Pekod
Jacob HaKohen of Nehar Peḳkod was the Gaon of Sura from 712 to 730.
Born in the late 7th century, Jacob was one of several community members who settled in Nehar Pekod. It was here that Jacob attained most of his schooling. He later migrated back to Sura, where he was elected head of the Gaonate, succeeding Rav Sheshna. Most scholars agree that Jacob served as Sura Gaon for eighteen years, although others state sixteen.
