Hamilton Naki was a black South African man who played a key role in the world's first heart transplant surgery in 1967, removing the donor heart, but was not given credit due to apartheid policies. Despite facing racial discrimination and low pay, Naki taught himself surgery by observing doctors and became a highly skilled surgeon, performing operations and lecturing students, though secretly due to his race. Naki dedicated his life to helping others through medicine despite facing injustice and lived quietly after apartheid ended.
