Whether or not a landowner has the right of possession of any archaeological resource that may exist on his land differs from country to country. Here in the United States the law favors the property rights of the landowner, in Italy - my native country - it does not.
Albert Viereck was born at his family farm at Neuhof-Kowas, not far from the city of Windhoek. A man with many interests, Viereck introduction to archaeology happened later in life after a visit to the painted shelters in the Brandberg mountains. Since South Africa then favored the rights of landowners (I don't know if the law had since changed) Viereck began collecting and recording artifacts and archaeological features on his farmland. He spent the following three decades researching and studying those artifacts and also ventured to investigate further away from his property; he recorded 129 archaeological sites, presented his results to international conferences and published papers and reports; all the while self-educating himself in the field. His largest collections were donated to the South West Africa Scientific Society a few years before his passing in 1982.
This quartzite point was presented to the museum by Viereck himself; I imagine through the auspices of prof. Clark who had joined the faculty at UC Berkeley in 1961 after his tenure at the National Museum of Zambia. The two men met in 1960 when Viereck participated to the Archaeological Winter School in Livingstone.
This type of tool is called a Stillbay point, after the prehistoric period during which it was made and used. It is the "type" point for the Stillbay period. The makers of similar points were hunter-gatherers of the Middle Stone Age who lived in southern Africa around and possibly before 65,000-70,000 years ago.
PAHMA has 17 Stillbay points and other tools, mostly from the Republic of South Africa and Kenya.
