John Edgar McFadyen B. A. (Oxon), M. A., D. D. (17 July 1870-1933) a Scottish theologian, was professor of language, literature and Old Testament theology in the University of Glasgow. He was born in Glasgow and died in 1933.
He produced translations of a number of books of the Bible in what he labelled "modern speech". His translations of Job and Psalms strove to be metrical, to reflect their poetic originals. He learned Esperanto in 1907 during a stay in Chautauqua, New York, and was a prominent proponent of that language.
