Born at
Vlissingen, around the age of six he moved with his parents to the
South African Republic. When British forces occupied
Pretoria in 1900 he was deported to the Netherlands, where he took classes and qualified as a mining engineer at the
technical university in Delft. He later received his doctorate with a thesis on the structure of the
Silurian strata of
Gotland (1910). He then returned to South Africa, where from 1910 to 1921, he worked as a paleontologist at the
Transvaal Museum. Within this time period, he focused his attention on fossil reptiles of the
Karoo. From 1922 to 1950 he served as director of
National Museum, Bloemfontein. He is credited with collecting thousands of
invertebrate fossils from the
Cretaceous strata of Zululand. He died at
Johannesburg. == Taxa ==
