Hetty Cohen-Koster was present at Cleveringa’s speech

'I belong here.' This is what the young Jewish law student Hetty Koster felt when she attended the memorable protest speech given by Professor Cleveringa on 26 November 1940. She managed to survive the war by going into hiding. She married Dolf Cohen, later Rector Magnificus of Leiden University, and had two sons: Floris and Job Cohen, now Professor of the Thorbecke chair.

These professors also stood up for their Jewish colleagues

With his speech in protest against the sacking of his Jewish colleague, Rudolph Cleveringa, Dean of the Faculty of Law, became the foremost symbol for Leiden’s resistance against the Nazis. But there are also other brave professors who should not be forgotten: what are the stories of Ben Telders, Ton Barge and Lambertus van Holk?
