*Dr. Daniel Jackson holds a Ph.D. in Anthropology as well as in Linguistics. He is an expert in ancient cultures, and speaks over 20 languages including ancient Egyptian. Jackson was originally contracted by the military to decipher a mysterious hieroglyphic cartouche, and his subsequent translation of it enabled the Stargate to be reactivated. He married Sha're, an off-world human and native of Abydos, after he chose to stay behind on the planet following the first mission. His humanistic, liberal outlook is often in conflict with O'Neil's ,ilitaristic approach.
