Charles Caldwell Ryrie (March 2, 1925 – February 16, 2016) was an American Bible scholar and Christian theologian. He served as professor of systematic theology and dean of doctoral studies at Dallas Theological Seminary and as president and professor at what is now Cairn University. He is considered one of the most influential theologians of the 20th century. He was the editor of The Ryrie Study Bible by Moody Publishers, containing more than 10,000 of Ryrie's explanatory notes. First published in 1978, it has sold more than 2 million copies. He was a notable advocate of classic premillennial dispensationalism.
Ryrie was born to John Alexander and Elizabeth Caldwell Ryrie in St. Louis, Missouri, and grew up in Alton, Illinois. After graduating from high school in 1942, he attended Stony Brook School on Long Island for one semester, where he became acquainted with headmaster Frank E. Gaebelein.
Ryrie attended Haverford College, intending on following his father into a banking career. However, during his junior year, while meeting with Dallas Theological Seminary founder Lewis Sperry Chafer, Ryrie dedicated his life to Christian ministry, and left Haverford to study theology at Dallas Theological Seminary. Haverford conferred his B.A. (1946) on the basis of his studies at Dallas. A year later, he earned his Th.M. (1947), and two years following that his Th.D. (1949). He went on to complete his Doctor of Philosophy (1953) at the University of Edinburgh. He also earned a Litt.D. from Liberty Baptist Theological Seminary, now Liberty University School of Divinity.
