Austin Marsden Farrer was a theologian and philosopher whom many consider to be an outstanding figure of 20th century Anglicanism. He served as Fellow and Chaplain of Trinity College, Oxford, 1935–1960.
He was the progenitor of the eponymous "Farrer hypothesis" suggesting that the Gospel of Mark was written prior to, and influenced, those of Matthew and Luke, in contradistinction to the "Q" theory of textual analysis more widely held outside Britain.
