Kirsopp Lake (7 April 1872 – 10 November 1946) was an English New Testament scholar, Church historian, and Winn Professor of Ecclesiastical History at Harvard Divinity School. He had an uncommon breadth of interests, publishing definitive monographs in textual criticism of the New Testament, Greek palaeography, theology, and archaeology. He is probably best known for the massive five-volume work The Beginnings of Christianity—an edition, translation, commentary, and study of the Acts of Apostles—that he conceived and edited with F. J. Foakes-Jackson and, among palaeographers, for the 10-volumes series of Dated Greek Manuscripts to the year 1200—edited with his second wife, Silva New—, one of the leading repertoires of facsimiles of Greek manuscripts.
