Amram (d. 875), a famous Gaon or head of the Jewish
Academy of Sura (
Persia) in the 9th century. He was author
of many
Responsa, but his chief work was liturgical.
He was the first to arrange a complete liturgy for the
synagogue, and his Prayer-Book (
Siddur Rab `Amram) was
the foundation of most of the extant rites in use among the
Jews. The
siddur was published in
Warsaw in two parts (1865).
