Hamilton Naki, South African surgeon (b. 1926)
Hamilton Naki (26 June 1926 – 29 May 2005) was a laboratory assistant to cardiac surgeon Christiaan Barnard in South Africa. He was recognised for his surgical skills and for his ability to teach medical students and physicians such skills despite not having received a formal medical education, and took a leading role in organ transplant research on animals.A controversy arose after his death in that at least five periodicals and the Associated Press retracted statements in their obituaries of Naki that claimed that he participated in the world's first human-to-human heart transplantation in 1967; the incident has been cited as an example of inadequate fact checking by the newsmedia and delayed corrections of the errors.
