Denis Goldberg, who was the only white to be jailed with Nelson Mandela, has been dubbed “the forgotten Rivonia man”. While Mandela and the other black Rivonia trialists were jailed together on Robben Island, Goldberg was sent to a whites-only jail in the shadow of the gallows at Pretoria Central, where he suffered twenty years of abuse from the white warders and fellow prisoners who branded him a traitor.
