Peter Allt, late of Trinity Coll., Dublin. - Russell K. Alspach in "The variorum edition of Yeats's plays": In 1956, shortly after completing the manuscript of The Variorum Edition of the Poems of W. B. Yeats, I began working on a variorum edition of the plays of Yeats that I finished in the spring of 1964. The book is dedicated to the memory of Peter Allt with whom I had collaborated on the poetry-variorum from 1947 until his tragic death in 1954
