A brief bio of Herman Bavinck, a continuing Reformer in the Protestant Reformation:
In the late 1800s and early 1900s, one of the most influential Reformed theologians was Herman Bavinck. He was a theology professor at Kampen Theological School (1883-1902) and the Free University of Amsterdam (1902-1921) in The Netherlands. John Bolt, former Professor of Systematic Theology at Calvin Theological Seminary in Grand Rapids, Michigan, called him “the real theologian of the nineteenth-century Dutch Calvinist revival.”
Bavinck’s development of Reformed theology was made popular in the United States through the influence of Louis Berkhof (1873-1957). Berkhof was a Professor at Calvin Theological Seminary for 38 years and was its first President. His most influential work was his Systematic Theology that became a popular textbook for Bible college and seminary students across the United States and Canada.
