Petru Maior
Petru Maior was a Romanian writer who is considered one of the most influential personalities of the Age of Enlightenment in Transylvania. Maior was a member of the Greek-Catholic clergy, a historian, philosopher, and linguist.
The Buda Lexicon, a book published in 1825, included two texts by Petru Maior, Orthographia romana sive latino-valachica una cum clavi and Dialogu pentru inceputul linbei române, in which he introduced the letters ș for and ț for, which have since been in use in the Romanian alphabet.
