Rescuing the Rivonia Trial recordings
A recording of Nelson Mandela’s remarkable speech delivered during the notorious Rivonia Trial of 1963-4, frequently quoted since his death last night at the age of 95, was heard for the first time in 2001 thanks to the British Library.
Speaking from the dock on 20 April 1964 during the Trial in Pretoria’s Palace of Justice, Mandela gave a spellbinding three-hour speech in his defence. Mandela (‘Accused Number One’) was charged with acts of sabotage designed to ‘foment violent revolution’.
His defiant closing words -
“the ideal of a free and democratic society in which all persons will live together in harmony and with equal opportunities…is an ideal for which I am prepared to die”
were widely reported in print and sent shockwaves around the world, leading to worldwide condemnation of South Africa’s racial policies. Mandela escaped the death penalty, but began a life sentence at Robben Island prison in June 1964. He was not released until 11 February 1990.
In 2000, during a visit to South Africa, a chance conversation between the British Library’s Oral History Curator Rob Perks and colleagues at the South African Broadcasting Corporation (SABC) and the National Archives of South Africa revealed that rare ‘Dictabelt’ recordings of the trial existed, but that no means had been found to replay or transfer the sound. Knowing that the British Library’s Sound Archive still owned one of the rare recorders, Rob offered to make the transfers.

Seven of the blue Dictabelts were loaned to the British Library and later returned to the custodianship of the National Archives of South Africa who retain all copyright in them. Discovering that the belts had been recorded at lower than normal speed in order to extend the recording time, Sound Archive audio engineers Peter Copeland and Adrian Tuddenham modified the Sound Archive’s Dictabelt machine to allow correct playback speed, which could be determined from low level mains hum, inadvertently recorded onto the belts at the time. By replaying the hum at the correct pitch it follows that the recording itself was replayed at the correct pitch. They also found they had to apply heat to the belts to smooth out the creases and allow playback with minimal groove-jumping.
The sound was then passed to Sound Archive engineer Nigel Bewley, who corrected the frequency response, carefully edited the sound to repair the groove-jumps and the reduced the surface noise using CEDAR (Computer Enhanced Audio Restoration). The resultant audio quality is remarkably clear considering the recording technology used, allowing Mandela’s speech to be heard again for the first time since the Trial.
The Rivonia Trial of 1963-4, one of the most important political trials of the twentieth century, marked a turning point in South Africa’s history and the struggle against apartheid. Attracting huge international attention at the time, ‘Rivonia’ led to the world-wide condemnation of South Africa’s racial policies.
On 9 October 1963 at the Palace of Justice in Pretoria, Nelson Mandela, Walter Sisulu, Dennis Goldberg, Govan Mbeki, Ahmed Kathrada, Lionel Bernstein, Raymond Mhlaba, James Kantor, Andrew Mlangeni and Elias Motsoaledi - leading members of the African National Congress (ANC) - were charged under the General Law Amendment (Sabotage) Act and the Suppression of Communism Act with acts of sabotage designed to foment ‘violent revolution’ and overthrow the state. Named ‘Rivonia’ after the Johannesburg suburb where sixteen ANC leaders had been arrested in July 1963, the full trial began on 3 December 1963 and culminated on 12 June 1964 in life sentences for eight of the accused. Nelson Mandela was the last to be released on 11 February 1990 after 27 years in jail.
