TengwarTengwar - The earliest Elvish script was created by a Noldor named Rúmil.  A generation later, Fëanor perfected Elvish writing with the invention of Tengwar.


"He became of all the Noldor, then or after, the most subtle in mind and most skilled in hand.  In his youth, bettering the work of Rúmil, he devised those letters which bear his name, and which the Eldar used everafter..." ~The Silmarillion, chap. 6 (Of Fëanor)
