Amram
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).
Based on an article from 1911 Encyclopedia Britannica.
Amram was a Levite, the husband of Jochebed and father of Aaron and Moses. Amram means "friend of the most high" i.e. friend of God.
