Bruynzeel House Painting by Hérine Fourie

Hans was an independent author and translator of scientific books. He also worked as consultant for lasers in Medicine and had his own company, Stellenbosch Scientific Instruments CC. Together with his sons he wrote a complex planning program for proton - radiotherapy: Proteus. It was the best of its kind for many years.
The story how this project was sabotaged by a jealous colleague, a mediocre physicist, still needs to be told.

Hans was married to Rosemarie, née Berg since 1967. They had three sons, Klaus (1968-2013), Hannes and Florian.

Hans is co-author of the book: Sailing with Piff and Mauz, 2012.
