W. B. Henning, who died at Berkeley, California, on 8 January 1967, at the early age of 58, was one of the small group of outstanding scholars drawn to Middle Iranian studies in this century by the wealth of new material discovered in Chinese Turkistan. The challenge of the unexplored attracted others also of the finest calibre, notably, among his contemporaries, H. W. Bailey and E. Benveniste; but Henning alone chose to concentrate his splendid gifts within this particular field.
