Frederick B. Macnutt (September 26, 1873 – July 17, 1949) was an English preacher, Anglican priest, and author whose ministry bridged parish service and wartime chaplaincy, influencing early 20th-century Anglicanism. Born in Brighton, England, to George Augustus Macnutt, a former doctor turned Baptist minister, and Isabella Ridge, he was one of seven children in an Irish-descended family that moved frequently, including stints in Canada and Australia. Educated at St. Paul’s School, London, and Trinity College, Cambridge (B.A. 1897, M.A. 1901), he earned an Athletics Blue before ordination as a deacon in 1898 and priest in 1899 at Canterbury Cathedral. Macnutt’s preaching career began as curate at Holy Trinity, Beckenham (1898–1901), and St. James’s, Piccadilly (1901–1902), followed by curate-in-charge at Christ Church, Wimbledon (1902–1903), and vicar roles at St. John’s, Cheltenham (1903–1907), and St. Matthew’s, Surbiton (1907–1918), where he also served as a canon of Southwark Cathedral (1909–1918). During World War I, he was a Temporary Chaplain to the Forces (1915–1918), preaching at the Chaplains School in St. Omer and on the Western Front. He later became vicar of St. Martin’s, Leicester (1918–1927), archdeacon of Leicester (1920–1927), and the first provost of Leicester Cathedral (1927–1938), then a residentiary canon at Canterbury Cathedral (1938–1946). Author of The Church in the Furnace (1917) and The Prayer Manual (1951), he preached on faith amidst adversity. Married twice—first to Hettie Sina Bullock (died 1945), with whom he had two children, Derrick and Margaret (died 1939), then to Evelyn May Oliver in 1946—he died at age 75 in Horsham, England.
