Lewis Sperry Chafer (1871–1952) was a Presbyterian clergyman, an educator, and the founder of Dallas Theological Seminary (originally Evangelical Theological College) in 1924, where he served as president and professor of theology until his death in 1952. Chafer was ordained in 1900 and traveled as an evangelist for 14 years before becoming a Bible lecturer from 1914–1924. Some of his most notable students include C. C. Ryrie, J. Vernon McGee, John Walvoord, and many others.
Chafer authored the eight-volume Systematic Theology, which was the first dispensational, premillennial systematic theology ever published. Several of Chafer’s other writings, such as Dispensationalism, Satan, and The Kingdom in History and Prophecy, can be found in the Lewis Sperry Chafer Collection (9 vols.). He also served as the editor of Bibliotheca Sacra, which was acquired by Dallas Theological Seminary in 1933.
