Stefaans was born in the early 1950s at Eenhand, Namibia. His father was a hunter. Both parents died when he was a child. As a young man he worked on a cattle farm in Okahandja.

Moving back to Eenhand, Stefaans became a subsistence farmer, cultivating mealies, mahango and other vegetables. He continued to hunt when possible. During the late 1970s, he received his military training at Omega in Namibia and worked for the South African Defence Force until leaving for Schmidtsdrift in 1990.

Working as an artist, Stefaans established himself as the one of the leading Bushmen artists. His works are extremely sought after both locally and internationally.

He used to remember the times when he was young, ‘In those days we would walk almost naked, just with a skin. It was only much later, when I was a young man, that I worked on a farm and bought clothes to wear. Then I traded my bow and arrow for a gun in the army. I was in face-to-face combat with the Swapo.

Stefaan’s art work was selected as the major art piece that is being displayed at Cape Towns’ International Convention Centre. It was decided that three of Samcuia's linocuts would be used and translated into three enormous, three-dimensional metal panels. This ended up being 28 metres in length and 7 metres high. It is probably the largest relief sculpture in South Africa.

Stefaans has sadly passed away from tuberculosis in June 2003. He leaves his wife, Teresia, five daughters and two sons.
