Karl-Ludwig von Bezing

from Wikipedia, the free encyclopedia

Karl-Ludwig "Ludi" von Bezing (* 1945 in Klagenfurt , Austria ) is an Austrian-South African mineral collector and amateur mineralogist . Von Bezing is a radiologist by profession . As a mineralogist he is self-taught and a specialist in minerals from Africa south of the Kunene and Limpopo , especially from South Africa and Namibia . He lives in Kimberley , the capital of the South African province of North Cape .

Live and act

After his parents emigrated to South Africa in 1949 and settled on a farm near Lydenburg, today's Mashishing in the Mpumalanga Province (the former Eastern Transvaal Province ), von Bezing began collecting minerals in the area at the age of ten the Drakensberg near Lydenburg. After high school and medical studies at the University of Cape Town from 1964 to 1969, von Bezing worked as a family doctor . Shortly before his specialization as a radiologist, an aunt died in Germany and left him a small mineral collection and a specialized mineralogical library. This was the beginning of a lifelong interest in mineralogy and minerals .

After completing his training as a radiologist, von Bezing started a private radiological practice in Kimberley - not least because of the city's proximity to the Kalahari manganese ore fields just 250 km further north.

As a result of his intensive occupation with the minerals from the Kalahari manganese ore fields, von Bezing was involved in the discovery and description of several new minerals from these sites, all of which were found by him for the first time. These include:

The processing of unknown dark brown crystals of a found in the early 1980s and to the American Museum of Natural History in New York City , New York State in the United States sent to identify the mineral from the "N'Chwaning II Mine" and the "Wessels Mine “Remained incomplete for a long time. After completing the information and sending the data for recognition as a new mineral to the International Mineralogical Association (IMA) in 1991, it turned out that the same mineral had just been recognized as Mozartite by an Italian site .

In addition to the minerals from the Kalahari manganese ore fields in South Africa, he is interested in the minerals from Namibia and especially the pegmatite minerals. This is expressed in the book he initiated, "Namibia: Minerals and Findings", for which he visited deposits and mineral deposits in Namibia countless times. This included a two-week excursion with Professor Paul Keller from the University of Stuttgart , during which the most important pegmatites in pegmatite-rich Namibia were visited.

At the age of ten, while playing on his parents' farm, he discovered fragments of terracotta masks, which are now known as Lydenburg Heads . Six years later, he presented these fragments to Ray Inskeep of the University of Cape Town, who identified them and confirmed their importance. After assembling the fragments, there were two life-size and five smaller masks that were later dated to an age of 500 BC. Were dated. They represent one of the earliest evidence of an Iron Age settlement in this area and remain unique in South Africa to this day.

Another field of activity for Ludi von Bezing is painting, whereby he mainly confines himself to motifs in the mineral kingdom and to landscapes. He is currently portraying minerals and their occurrences, mainly with watercolor and colored pencil.

Karl-Ludwig von Bezing has been married since 1972. The marriage had two children.
