Wheaton College has graduated several students who’ve eventually assumed the presidencies of schools and agencies. Less common is the fact that one Wheaton College teacher, Dr. C. Raymond Ludwigson, serving on staff as Associate Professor of Bible and Philosophy, departed its faculty to accept a college presidency; then, after a six year stint, returned to Wheaton College, resuming his teaching position. An alumnus of Moody Bible Institute and Wheaton College, Ludwigson earned his graduate degree from Chicago Lutheran Seminary and his doctorate from the University of Iowa. Dr. Ludwigson taught at Wheaton College until his appointment in 1949 to the presidency of Trinity College and Seminary in Chicago (now Trinity International University in Deerfield, IL). However, he returned to Wheaton College in September 1955. Throughout his teaching career and after he served as interim pastor at various churches, including Westminster Presbyterian Church in Elgin, IL. Ludwigson was known for a warm, devotional teaching style. He retired from Wheaton College in 1969 and in 1973 published A Survey of Bible Prophecy for Zondervan.
