Nicoll was born in Lumsden, Aberdeenshire, the son of Rev Harry Nicoll, a Free Church minister of Auchindoir, and his wife, Jane Robertson. He was educated at Aberdeen Grammar School and graduated MA at the University of Aberdeen in 1870, and studied for the ministry at the Free Church Divinity Hall there until 1874, when he was ordained minister of the Free Church at Dufftown, Banffshire. Three years later he moved to Kelso, and in 1884 became editor of The Expositor for Hodder and Stoughton, a position which he held until his death. In 1885, Nicoll was forced to retire from pastoral ministry after an attack of typhoid had badly damaged his lung. In 1886, he moved south to London, which became the base for the rest of his life. With the support of Hodder and Stoughton he founded the British Weekly, a Nonconformist newspaper, which also gained great influence over opinion in the churches in Scotland. Nicoll secured many writers of exceptional talent for his paper, to which he added his own considerable talents as a contributor. He began a highly popular feature, "Correspondence of Claudius Clear", which enabled him to share his interests and his reading with his readers. He was also the founding editor of The Bookman from 1891, and acted as chief literary adviser to Hodder and Stoughton. Among his other enterprises were The Expositor's Bible and The Theological Educator. He edited The Expositor's Greek Testament. He also edited a series of Contemporary Writers, and of Literary Lives. He projected, but never wrote, a history of The Victorian Era in English Literature, and edited, with T. J. Wise, two volumes of Literary Anecdotes of the Nineteenth Century. He was knighted by King Edward VII in 1909, ostensibly for his literary work, but in reality probably more for his long-term support for the Liberal Party. He was appointed to the Order of the Companions of Honour in the 1921 Birthday Honours. Nicoll was the father of Maurice Nicoll, a leading British psychologist and author who studied under Carl Jung and became a leading expositor of the teachings of the Greco-Armenian spiritual master G.I. Gurdjieff. He died on 4 May 1923 at his home, Bay Tree House in London.
