T'Klaas

From Memory Alpha, the free Star Trek reference.

T'Klaas was a Vulcan student of Surak and one of the first Kolinahr masters who died 1,800 years prior to the 22nd century.

His mummified body was entombed in the catacombs of the T'Karath Sanctuary. Since there was no inscription, the identity of his remains, in terms of origin of his bloodline, were unknown until 2154, when Captain Jonathan Archer, holding the katra of Surak, identified him. (ENT: "Awakening")
