Gates added that he personally met the South African leader through the fight against HIV/AIDS. He also shared a photo showing Mandela, his father and former president Jimmy Carter holding infants infected with HIV.

Gates said the photo was intended to allay fears and stigma surrounding touching people with HIV. He called the photo his favorite photo.

“Mr Mandela exemplified how we can fight for progress, break down stigma and spread hope. He has played a critical role in the progress we have made against HIV/AIDS to date,” Gates said. “I will never forget the example he set.”
