AMRAM GAON

'Amram Gaon' (Hebrew: 'עמרם גאון') (d. 875) was a famous ''Gaon'' or head of the Jewish Talmud Academy of Sura (Persia) in the 9th century. He was the author of many ''Responsa,'' but his chief work was liturgical.
He was the first to arrange a complete liturgy for the synagogue. His Prayer-Book (''Siddur Rab Amram'' or ''Seder Rav Amram''), which took the form of a long responsum to the Jews of Spain, is still extant and was the foundation of most of the current rites in use among the Jews. The ''siddur'' was published in Warsaw in two parts in 1865.
Later editions are:

★ ''Seder Rav Amram Gaon'', ed. Hedegard: Lund 1951

★ ''Seder Rav Amram Gaon'', ed. Goldschmidt: Jerusalem 1971

★ ''Seder Rav Amram Gaon'', ed. Kronholm: Lund 1974

★ ''Seder Rav Amram Gaon'', ed. Harfenes: Bene Berak 1994
No early manuscripts of this prayer book survive, and later manuscripts appear to be heavily edited to conform with the rites in use at the time: we therefore cannot be certain of the exact wording preferred by Amram Gaon himself.
