Open Stellenbosch, a movement of mostly black students and staff, wants the university to investigate the activities of staff and guest lecturers during apartheid. The call was made in the wake of revelations that apartheid-era chemical warfare expert Wouter Basson tutored Stellenbosch University students earlier this year. Basson, who works at a private hospital, gave tutorials to fourth-year medical students at the company's Durbanville premises, in Cape Town.In 2013, the Health Professions Council of SA found Basson guilty of unprofessional conduct on four charges related to his role in the apartheid security apparatus."It is immoral for the university to be associated with Basson and allow someone who carried out biological warfare to make contact with students," said Simone Cupido, the movement's spokesman.Cupido said the university had been evasive about its relationship with Basson.A medical student who asked not to be named said she attended Basson's tutorial in February."I was extremely uncomfortable with him teaching us.
