Cairns Craig, Glucksman Professor of Irish and Scottish Studies, recounts the influence of the first holder of the chair in English Literature at Aberdeen University, Professor H.J.C. Grierson. Grierson was closely involved with major poets of the early twentieth century, such as W.B. Yeats and T.S. Eliot, because of the influence of his edition of the poems of John Donne (OUP, 1912), which set the standard for the critical analysis of poetry for next half century.
