In 2008, Unisa lecturer Annet Wanyana Oguttu became the first black woman in South Africa to complete a Doctorate in International Tax Law. In 2010, she became the first black female professor at Unisa’s College of Law.

In 2012, Oguttu was the second runner-up in the Distinguished Women in Science Awards (Social Sciences and Humanities category) for her “outstanding contribution to building South Africa’s scientific and research knowledge base”. This was a characteristic achievement in an already exemplary career. Born in Uganda, Oguttu achieved her first legal qualifications at Makerere University, Kampala. In 1993, she became an advocate in Lesotho’s High Court and in 2001, began her doctorate through Unisa, later moving to Pretoria to combine her doctoral studies with lecturing at Unisa. Her ongoing research towards developing tax law has won honours, including an award for academic excellence from the University of Michigan where she pursued her postdoctoral studies, as well as Unisa’s Top Performer award in 2010 and a Unisa Women of the Year award in 2011.
