Teddy Bear Clinic director Dr Shaheda Omar says Xolani Gwala had a natural love for children.
Gwala died on Friday morning after a long battle with cancer.
In 2017, the journalist and broadcaster ran the London Marathon as part of an on-air campaign with Virgin Atlantic, to raise awareness around the Teddy Bear Clinic and secure funding for the organisation.
Omar says Gwala's vision was to ensure the safety of children.
That speaks about a legend and somebody who really cared and went beyond the call of duty. He did this because he was just a passionate soul that cared far too much.— Dr Shaheda Omar, Director - Teddy Bear Clinic
