Donald Campbell McLaren was born in New York City, October 2, 1794. Graduating from Union College, Schenectady, New York, he studied theology under Dr. John M. Mason. In 1813, he was licensed to preach by the Saratoga Presbytery, of the Associate Reformed Synod of New York. In April, 1819, he was ordained the pastor of the Associate Reformed congregation, in Cambridge, New York. During his long career, he served as the moderator of the General Synod of the A.R. church, in 1858; and, again, as moderator of the Synod of New York, in 1864. He was an able debater in matters that came before the courts of the church. He published several shorter works together with a metrical version of the Psalms. His work, on the subject of Psalm singing, is his most enduring work. He retired to Geneva, New York, where he died, May 7, 1882.
