The honorary doctorate of Nelson Mandela
29 May 2018
2018 will mark the centenary of the birth of Nelson Mandela (1918-2013), former President of South Africa. Mandela received an honorary doctorate from Leiden University in 1999. The then Rector Magnificus Willem Wagenaar honoured Mandela as ‘a true defender of freedom’. We celebrate the legacy of Nelson Mandela by organising a lecture on 1 June 2018. More information here.
