Ronald Stephen McCoy: Enduring legacy of courage, compassion and hope

DATUK Dr Ronald Stephen McCoy, the renowned Malaysian obstetrician and gynaecologist, physician, humanitarian and lifelong campaigner for nuclear disarmament, passed away on Sept 1, 2026 at the age of 96. With his passing, Malaysia lost an extraordinary doctor whose lifelong career was dedicated to two seemingly different causes — the noble calling of bringing new life into the world and advocating for the global struggle against the catastrophic consequences of nuclear war. Born in Seremban in 1930, McCoy was educated at Victoria Institution in Kuala Lumpur, where he distinguished himself not only academically but also on the sporting field. He later entered the University of Malaya in Singapore in 1949 as part of its first intake of medical students. Medicine became his life's vocation. He trained in obstetrics and gynaecology and went on to serve at Kuala Lumpur General Hospital, Assunta Hospital and Pantai Medical Centre, becoming one of the founding members of Pantai Medical Centre. Over approximately four decades of medical practice, he delivered 20,000 babies — an extraordinary legacy measured not in statistics alone, but in the thousands of Malaysian families whose lives he touched with the miracle of birth. He retired from clinical practice in 1996. However, McCoy's conception of a doctor's responsibility was far reaching. His experiences during the Second World War, and particularly his reflections on the atomic bombings of Hiroshima and Nagasaki, left him deeply concerned about the destructive effects of nuclear weapons. He believed that doctors had a special mission to warn humanity about a catastrophe for which medicine could offer no adequate response. In 1987, he founded the Malaysian Physicians for the Prevention of Nuclear War, linking Malaysian doctors to the international movement against nuclear weapons. He subsequently became vice-president of the International Physicians for the Prevention of Nuclear War (IPPNW) for the Asia-Pacific region and served as its co-president for eight years. IPPNW had itself been awarded the 1985 Nobel Peace Prize for its efforts to raise awareness of the medical consequences of nuclear war. McCoy's most enduring contribution to the global peace movement, however, came after the failure of the 2005 review of the Nuclear Non-Proliferation Treaty. Frustrated by the lack of progress, he proposed a new international grassroots campaign modelled on the successful campaign against landmines. He suggested the name International Campaign to Abolish Nuclear Weapons (ICAN). The idea was subsequently developed into a worldwide movement. Launched in 2007, ICAN grew into a coalition of hundreds of organisations campaigning for a legally binding prohibition of nuclear weapons. In 2017, its extraordinary efforts were recognised when ICAN was awarded the Nobel Peace Prize. For McCoy, however, the campaign was never about personal recognition. It was about the future of humanity — particularly the future of children, some of whom he had helped bring into the world. He often connected his anti-nuclear activism to his work as an obstetrician, arguing that the thousands of babies he had delivered deserved to grow up in a world free from the threat of nuclear annihilation. His contribution to public life certainly extended beyond medicine and nuclear disarmament. He served as president of the Malaysian Medical Association and participated in Malaysia's delegation to the International Court of Justice in 1995 during its consideration of the legal status of nuclear weapons. He was also a member of the Canberra Commission on the Elimination of Nuclear Weapons. McCoy's legacy is undoubtedly profound. He was a Malaysian who carried his country's voice onto the international stage, a peace activist who refused to accept nuclear annihilation as an inevitable part of humanity's future. Twenty thousand babies entered the world through his hands. His life's work was to ensure that they, and the generations that followed them, would inherit a world worthy of them. McCoy leaves behind a legacy of courage and compassion. He is survived by children Stephen, David and Ruth and grandchildren Lara, Miraya, Sacha and Hannah. May he rest in peace.
