Renfrew Christie was a white South African scientist and member of the paramilitary wing of the African National Congress. He went to Oxford University and studied South Africa's history of electrification "so I could get into the electricity supply commission’s library and archives, and work out how much electricity they were using to enrich uranium," he told the BBC. That in turn let them figure out how much enriched uranium South Africa had, and many bombs it could build.
When he returned to South Africa, he was arrested and, after 48 hours of torture, wrote a forced confession, which he told the BBC was the best thing he ever wrote
noting that he had made sure the confession included “all my recommendations to the African National Congress” about the best way to sabotage Koeberg and other facilities.
“And, gloriously, the judge read it out in court,” Dr. Christie added. “So my recommendations went from the judge’s mouth” straight to the A.N.C.
Christie died of pneumonia last month, at the age of 76.
