A Dutch-American Reformed theologian. Berkhof was born in the Netherlands but moved to the United States as a child. He studied for several years under B. B. Warfield and Geerhardus Vos at Princeton Seminary and was ordained in the Christian Reformed Church. After several years of pastoral experience, he taught biblical studies and systematic theology at Calvin Theological Seminary, later serving there as president until his retirement in 1944. His most influential academic work was Systematic Theology (1938), which drew heavily from Reformed scholasticism; it became a widely accepted and utilized summary of Reformed theology.
