Rev. Percy Dearmer (1867–1936) was an English priest and liturgist who was dedicated to social justice throughout his life. He was ordained to the diaconate in 1891 and to the priesthood in 1892 at Rochester Cathedral. As a member of the Alcuin Club, he campaigned for a revived English Catholicism that was rooted in pre-Reformation ritual. His best-known work, The Parson’s Handbook, was the product of his work in that area. Dearmer served as chaplain to the British Red Cross ambulance unit in Serbia during WWI, as secretary of the Christian Social Union, and as a canon of Westminster Abbey in 1931. He died in 1936 and his ashes are interred in the Great Cloister at Westminster Abbey.
