Rav Avraham bar Sherira מר רב אברהם בן מר רב שרירא
Gaon of Pumbedita from 816, twelve years in office through the schism of the rival nesi'im Daniel and David — when his av beit din Yosef bar Chiya was also acclaimed gaon, until Yosef publicly renounced the title and Avraham blessed him for the world to come.

| No source names his teacher. Per this atlas's succession roster, Rav Menashe bar Yosef held the headship of his academy during his formative window (c. 4541–4561 AM), making reception from him the likeliest reconstruction.
Derived by era-and-institution inference, not attested. The formative window is computed from this entry's schematic dates, hence the low confidence.
