Dr. John C. Whitcomb has been a professor of Old Testament and theology for more than 50 years, and is widely recognized as a leading Biblical scholar. He taught at Grace Theological Seminary in Winona Lake, Indiana, from 1951-1990, and gained much recognition for his work on The Genesis Flood (Presbyterian and Reformed Publishing Company), which he co-authored with Dr. Henry Morris in 1961. This book has been credited as one of the major catalysts for the modern Biblical creationism movement.

Among Dr. Whitcomb's other published works are The Early Earth and The World That Perished (Baker Book House), and commentaries on Esther and Daniel (Moody Press). Additionally, he has authored six comprehensive Bible charts, numerous multi-media slides, and countless Biblical and theological articles. Major emphases in his teaching have been Biblical creationism, dispensational theology, premillennial eschatology, and presuppositional apologetics.
