Culture of South Africa originated in South Africa. The first human-to-human heart transplant was performed by cardiac surgeon Christiaan Barnard at Groote Schuur Hospital in December 1967. Max Theiler developed a vaccine against Yellow Fever, Allan McLeod Cormack pioneered x-ray Computed tomography, and Aaron Klug developed crystallographic electron microscopy techniques. These advancements were all (with the exception of that of Barnard) recognised with Nobel Prizes. Sydney Brenner won most recently, in 2002, for his pioneering work in molecular biology. Mark Shuttleworth founded an early Internet security company Thawte, that was subsequently bought out by world-leader VeriSign. South Africa has cultivated a burgeoning astronomy community.
Nobel Peace Prize the prize, profoundly influenced his decision to include peace as a category. Some Nobel scholars suggest it was Nobel's way to compensate for developing destructive forces. His inventions included dynamite and ballistite, both of which were used violently during his lifetime. Ballistite was used in war and the Irish Republican Brotherhood, an Irish nationalist organization, carried out dynamite attacks in the 1880s. Nobel was also instrumental in turning Bofors from an iron and steel producer into an armaments company. It is unclear why Nobel wished the Peace Prize to be administered in Norway, which was ruled in union with Sweden
