The Rev. Dirk Postma was not only the founder of the Reformed Church of South Africa (Gereformeerde Kerk), but also made significant contributions in the field of education. In this article the leading role he played with regard to the promotion of Christian education in the Netherlands (IH4H-1859) and in South Africa (1859-1890) is outlined. He was responsible for the establishment of the first Christian school in Zwolle and his dynamic involvement in education in South Africa had the result, among others, that the Potchefstroom University for Christian Higher Education came into being. His worthwhile activities in the sen’icc of Christian education are an example for present-day Christian educators in South Africa to tackle the educational problems which are rife at present and possibly to solve them in a like manner.
