Born in 1950 and raised in a traditional Afrikaans home, Johan was instilled with the fear of God and respect for His Word, the Bible, from a very young age. However, his faith was challenged when he sought advice from one of his ‘agnostic’ zoology lecturers at university—asking if it was possible to ‘reconcile’ the Bible with evolution.
Over the next 10 years—and while reading up on both sides of the creation/evolution controversy—he completed an M.Sc. in animal reproductive physiology in 1982, and a Ph.D. in nematology in 1986. He also worked as a technical/research assistant, and then as a postdoctoral research fellow.
Later, as a senior zoology lecturer at a local university, he was responsible for Human and Sports Physiology courses, and also developed Biology courses for a teachers training program. He has authored/co-authored 22 research articles which have been published in peer-reviewed scientific journals.
As the founder of Creation Ministries International (South Africa), Johan desires to see biblical foundations restored to the church. He is fully persuaded that the ministry’s uncompromising approach, i.e. upholding the authority of God’s Word, the Bible, from the very first verse (connecting it to all of reality and pointing out that God, not man, determines truth) will motivate and equip Christians to defend their faith against the evolutionary indoctrination that is so prevalent in society today. He also believes that this will awaken Christians to the wonders of God's creation, the evidence of design in nature, and most of all, the urgent need to proclaim the Gospel of Jesus Christ-as Sovereign Creator, Redeemer and Judge.
Johan and his wife Dianne (a nursing sister) live in Aurora, Durbanville. They have no children of their own.
