The Reverend Percy Dearmer MA (Oxon), DD, (1867-1936) was an English priest and liturgist best known as the author of The Parson's Handbook, a liturgical manual. A lifelong socialist, he was an early advocate of the ordination of women to public ministry but not to the priesthood, and very concerned with social justice. He had a strong influence on the music of the church and, with Ralph Vaughan Williams and Martin Shaw, is credited with the revival and spread of traditional and medieval English musical forms. In 1901, after serving four curacies, Dearmer was appointed the third vicar of London church St. Mary-the-Virgin, Primrose Hill, where he remained until 1915. His works include: Christian Socialism and Practical Christianity (1897), The English Liturgy (1903), The English Hymnal (1906), Socialism and Religion (1908), The Church and Social Questions (1910) and Reunion and Rome (1911).
