Percival Dearmer (1867–1936) was an English Anglican priest and liturgist best known as the author of The Parson's Handbook, a liturgical manual for Anglican clergy, and as editor of The English Hymnal. A lifelong socialist, he was an early advocate of the public ministry of women and concerned with social justice. Dearmer, with Ralph Vaughan Williams and Martin Shaw, helped revive and spread traditional and medieval English musical forms. His ideas on patterns of worship have been linked to the Arts and Crafts Movement, while The English Hymnal reflects both folkloric scholarship and Christian Socialism. At his death, he was a canon of Westminster Abbey, where he ran a canteen for the unemployed.

Martin Edward Fallas Shaw was an English composer, conductor, and theatre producer. His over 300 published works include songs, hymns, carols, oratorios, several instrumental works, a congregational mass setting, and four operas including a ballad opera.
