William Dool Killen

William Dool Killen (1806–1902). Born on April 16, 1806, in Ballymena, County Antrim, Ireland, to John Killen, a grocer, and Martha Dool, William Dool Killen was a Presbyterian minister, church historian, and educator. The third of nine children, he attended Ballymena Academy and, in 1821, entered the Royal Academical Institution in Belfast, studying under James Thomson. Licensed to preach in 1827 by the Ballymena Presbytery, he was ordained in 1829 as minister of Raphoe, County Donegal, where he served diligently while immersing himself in church history. In 1841, he became professor of church history, ecclesiastical government, and pastoral theology at the Presbyterian College in Belfast, succeeding James Seaton Reid, and was appointed president in 1869, retiring from teaching in 1889 but continuing as president until his death. Killen’s preaching, notably in a 1839 Derry debate defending Presbyterianism against prelacy, earned him recognition, with his sermon published in The Plea of Presbytery (1840). A prolific author, he wrote The Ancient Church (1859), Continuation of Reid’s History of the Presbyterian Church in Ireland (1853), and The Old Catholic Church (1871), blending meticulous research with evangelical zeal. Married to Anne Young in 1830, he had three sons and five daughters; Anne died in 1886. Killen died on January 10, 1902, in Belfast, buried in Balmoral Cemetery, saying, “The history of the church is the history of God’s truth.”
