Cornelius Van Til (1895–1987) was born in Grootegast, the Netherlands, and immigrated with his family to America in 1905. He attended Calvin College and Calvin Seminary before completing his studies at Princeton Theological Seminary and Princeton University with the ThM and PhD degrees.
Drawn to the pastorate, Van Til spent one year in the ministry before taking a leave of absence to teach apologetics at Princeton Seminary. When the seminary reorganized, he was persuaded to join the faculty of the newly founded Westminster Theological Seminary. He remained there as professor of apologetics until his retirement in 1972.
Van Til wrote more than twenty books, in addition to more than thirty syllabi. Among his best-known titles are The Defense of the Faith, A Christian Theory of Knowledge, and An Introduction to Systematic Theology.
