by E. G. P. (Edward Gerald Penfold) Wyatt
Edward Gerald Penfold Wyatt, born in 1869, wrote under the name E. G. P. Wyatt. Catalog records and digitized editions connect him with books on liturgy, ceremonial practice, and church music, including St. Gregory and the Gregorian Music, English or Roman?, and The Eucharistic Prayer.
His work shows a strong interest in the traditions of Christian worship, especially the history and use of plainsong and ceremonial forms. He was also linked in publication records with the Plainsong and Mediaeval Music Society, which fits the focus of his writing on Gregorian chant and older liturgical practice.
Little biographical information appears to be readily available in the sources I could confirm, so the personal side of his life remains obscure. Even so, his books leave a clear impression of a careful, scholarly writer whose interests lay in the meeting point of music, devotion, and church tradition.
