He returned to South Africa to complete his degrees, MB and ChB, in 1948. He was an intern at Groote Schuur Hospital, and then a lecturer at the University of Cape Town Medical School. He married his first wife, Margaret Rosenberg in 1949, and they lived in Newlands. They had two sons.
He spent some time serving under Albert Schweitzer at Lambaréné in French Equatorial Africa (now Gabon), and travelled to the United States in 1957–8 under a Carnegie Fellowship, and started to specialise in endocrinology. He obtained his MD in 1957 and PhD in 1968. He was a lecturer at the Department of Medicine at the University of Cape Town from 1955 to 1967. He also continued to practise medicine at Groote Schuur Hospital, where he was involved preparing for Christiaan Barnard's first heart transplant operation in 1967.
He ran into political difficulties in South Africa.[1] He opposed the apartheid policies of the National Party, and supported Alan Paton's Liberal Party,[1] which he had joined in 1953. He had been a friend of Paton and of the party's chairman, Peter Brown, since they were students together in Cape Town. He supported the National Union of South African Students, and was chairman of the Defence and Aid Fund, which funded the defence of those accused of political crimes and supported their families, until it was banned in 1966.
In July 1967, the Prime Minister John Vorster imposed a banning order under the Suppression of Communism Act which prohibited him from all political and social activity for 5 years. By now, he had an international reputation as a leading endocrinologist, and the banning order led to widespread protest.
He and his family were given an "exit permit" to leave South Africa in 1968, on condition that they did not come back. He moved to the United Kingdom, where he continued to lend support to the campaign against apartheid. The exiled Oliver Tambo was a patient for many years.
He retired in 1993, and he and his wife joined his two sons in Australia. He moved to Queensland, where he was professor of medical ethics at the University of Queensland from 1993 to 1995.
Death and legacy
After the death of his first wife in 2005, he married Countess Madeleine Douglas in 2006. He died in Oxford. He was survived by his second wife, and his two sons from his first marriage.
