Born of Dutch parents on the farm Melkhoutskraal, Volschenk started painting when still a child and was largely self-taught.
James Reitz, the Government Land Surveyor, saw some of his drawings and suggested that his brother Gysbert, a Riversdale lawyer, take an interest.
His home district around Riversdale and the Langeberg, was his inspiration and subject matter, and he became a master of the subtle colours and tones of the Karoo mountains.
Volschenk's keen powers of observation spilled over into natural history - he amassed a collection of more than 4 000 beetle specimens.
When 45 years old, Volschenk married another Riversdale resident, Helen Smalberger, and they produced a family of nine daughters.
