While Percy Dearmer’s influence on Anglican liturgy through The Parson’s Handbook and The English Hymnal are well known, his lectures on The Art of Public Worship, given in 1919 when he was visiting professor at Berkeley Divinity School in Connecticut, USA, introduce a different phase of his liturgical thought. A new emphasis on modernizing language, brevity of form, and alternative forms of worship would later have expression in England via his association with the Guildhouse in London, and in the hymnal Songs of Praise. Comparing The Art of Public Worship with the later Prayer Book Interleaves by Berkeley Divinity School’s Dean William Palmer Ladd leads to the suggestion that this ‘second Dearmer’ also had an afterlife in the American liturgical movement.
