Amram Gaon, or Amram of Sheshna, was a ninth-century gaon, or head of the talmudic academy in Sura, Babylonia. He authored responsa and was the first known author to compile a set liturgy to be recited in prayer services. This work, known as Siddur Rav Amram or Seder Rav Amram, was an important influence on the development of Jewish liturgy.
