Nicholas ‘Fink’ Haysom, a key figure in South Africa’s constitutional process and a United Nations diplomat, died on 18 March 2026 in New York City after a short illness. He was 73 and serving as the UN special representative for South Sudan. Haysom leaves behind his wife Delphine, five children and a sister.
Nicholas “Fink” Roland Leybourne Haysom was born on 21 April 1952. His nickname originated from a hospital mix-up at birth, when he was briefly swapped with another infant and returned wearing a Finkelstein label. Educated at Michaelhouse, the University of Natal and the University of Cape Town—where he served as Students’ Representative Council president and National Union of South African Students leader in 1976—Haysom faced detention without trial multiple times, including solitary confinement, and a two-year banning order during apartheid repression following the Soweto uprising. He co-founded the human rights law firm Cheadle Thompson & Haysom and worked as an associate professor at Wits University’s Centre for Applied Legal Studies, handling cases on vigilante violence, labour law and forced removals. In 1987, he won South Africa’s Playwright of the Year award for The Native Who Caused All the Trouble. Haysom mediated truces in Thokoza, contributed to South Africa’s interim and final Constitutions, and advised President Nelson Mandela on legal and constitutional matters. Zelda la Grange, Mandela’s private secretary, noted that Mandela entrusted him with resolving complex processes. Later, he supported democracy efforts in Zimbabwe, as recalled by David Coltart, who praised his steadfastness and humility. Haysom’s UN career included roles in Burundi, Iraq—where he aided constitutional drafting—Afghanistan, Timor-Leste, Sri Lanka, Colombia, Myanmar, Indonesia and Sudan-South Sudan peace processes. UN Secretary-General António Guterres described him as devoting his life to justice, dialogue and reconciliation with deep legal insight. Tributes highlighted his listening skills and humanity, from Jay Naidoo on his solidarity to Abdul Mohammed on dignifying diplomacy. The illness’s nature remains undisclosed.
