Alex Boraine had cancer and was in remission from the dreaded disease. He had a fall a week back and discontinued taking foods. His son Jeremy Boraine said that he was asleep when he died, so the exact time of death was not known.
After the end of white-minority rule in 1994, Nelson Mandela, South Africa's first democratically elected president, appointed Archbishop Desmond Tutu to chair the TRC with Mr Boraine as his deputy, BBC noted.
The TRC was set up to investigate the crimes committed by all sides during the apartheid regime - and to recommend whether people confessing their involvement should receive amnesty.
Alex travelled to many countries that are in transition from dictatorship to democracy, at the invitation of governments and NGOs, to share the South African experience. He was also a member of Advisory Board of Directors and a Global Visiting Professor of Law at the NYU School of Law's Hauser Global Law School Program.
