The Kaisers recognised the need to support the development of cadre of black medical professionals to serve the majority of people who were denied access to quality health care because of their race. Dr Nthato Mothlana, a prominent South African physician, assisted in taking the initiative forward.

At that time, George Soros contributed $250 000 to MESAB after meeting Dr Motlanthe. Support continued until 2002. George Soros remains one of MESAB’s largest donors. By the time MESAB concluded its work in 2007, it had helped to train more than 10 000 black health professionals in South Africa.
