Nicholas Sims-WilliamsGeorg Morgenstierne (1892-1978), Emeritus Professor of Indian philology in the University of Oslo, was recognised as the uncontested master of Iranian and Indo-Iranian dialectology. Many of his numerous publications were devoted to the languages of Afghanistan and to the "Indo-Iranian Frontier languages", the little-known dialects spoken on the border between Afghanistan and Pakistan, some of which he was the first to describe. The compilation and edition of this posthumous work by Morgenstierne was initiated by the late D. N. MacKenzie (Professor Emeritus of Oriental Philology, University of Gottingen) and has been completed by Josef Elfenbein and Nicholas Sims-Williams. Read More Read Less
