Sir Samuel Layinka Ayodeji Manuwa was one of the most important Nigerian medical figures of the twentieth century. His career belonged to a period when Nigeria was still under British colonial rule and senior administrative positions were largely controlled by expatriate officials. Through training, discipline, surgical excellence, and public service, Manuwa rose into the highest levels of medical authority and became a major figure in the transformation of Nigerian healthcare.
Early Education in Lagos
Manuwa was born in 1903 and received his early education at King’s College, Lagos, one of the leading schools that trained many members of Nigeria’s early professional class. His education placed him among a generation of Nigerians who used scholarship and professional training to challenge the limits imposed by colonial society.
Medical Training in Britain
He later travelled to Britain for medical training at the University of Edinburgh, where he qualified in medicine in 1926. He also studied tropical medicine in Liverpool, a field of great importance for doctors working in West Africa, where diseases and medical conditions were often shaped by climate, poverty, sanitation, and colonial public health systems.
Return to Nigeria
In 1927, Manuwa returned to Nigeria and joined the Colonial Medical Service as a medical officer. This was not an easy environment for African professionals to advance. Nigerian doctors could serve within the system, but the most senior posts were still dominated by Europeans.

Manuwa’s rise was not only a personal success. It reflected the gradual opening of professional space for Nigerians in a colonial structure that had long limited African authority. His career showed that medical excellence could become a pathway into leadership, even within a system shaped by racial hierarchy.
A Reputation Built in Surgery
For many years, Manuwa worked mainly as a surgeon. This part of his career is essential to understanding his later influence. He first built a reputation through direct medical work, and his skill in surgery earned him respect among colleagues and administrators.
Manuwa continued practising medicine and surgery for more than eighteen years before accepting senior administrative responsibilities. This long period of clinical service gave weight to his later leadership because he understood the realities of medical work from the operating theatre and hospital ward, not only from government offices.
The Tropical Ulcer Knife
One of his best known medical contributions was his invention of an excision knife used in the treatment of tropical ulcers. Tropical ulcers were a serious health problem in West Africa, and Manuwa’s work showed his practical concern with the medical realities of the region.
A Published Medical Contribution
His 1946 article, “An excision knife for tropical ulcers,” published in the British Medical Journal, remains one of the clearest documentary traces of this contribution. It shows that his reputation was not based only on later memory, but on recorded professional achievement.
In 1948, Manuwa became Deputy Director of Medical Services. This appointment placed him among the senior figures in Nigeria’s medical administration at a time when few Nigerians held high offices within the colonial public service.
First Nigerian Director of Medical Services
In 1951, he became Director of Medical Services, widely recorded as the first Nigerian to hold that position. He later served as Inspector General of Medical Services and Chief Medical Adviser to the Federal Government of Nigeria.
Medical Leadership Before Independence
These appointments placed Manuwa at the centre of medical administration during a period when Nigeria was moving towards self government. His position gave him influence over health policy, medical planning, and the development of institutions that would shape Nigerian medicine after independence.
The Meaning of Nigerianisation
His rise was part of the wider process often described as Nigerianisation. This was the gradual movement of Nigerians into senior public service positions that had previously been reserved mainly for expatriate officers.
Nigerianisation did not happen at once, and it did not immediately remove inequality from colonial administration. It was slow, uneven, and shaped by political pressure, professional qualification, and administrative caution. Manuwa’s career became one of the clearest examples of that transition in the medical service.
A Major Figure in Medical Education
Manuwa’s importance also lies in his connection to medical education. He was strongly associated with efforts to establish a modern university teaching hospital in Nigeria, especially the development of University College Hospital, Ibadan.
His Role in UCH Ibadan
Manuwa was a major advocate and senior medical figure in the movement that helped bring such an institution into being. His influence belonged to a wider process that involved several government, university, medical, and colonial bodies.
University College Hospital, Ibadan, developed through a wide institutional process involving government authorities, University College Ibadan, the University of London, medical boards, advisers, architects, and administrators.
Development in the 1950s
The Colonial Office Report on Nigeria for 1955 shows that work on the future teaching hospital was still in progress that year. Several major blocks had been structurally completed, and plans were being made for the transfer of hospital services from Adeoyo and Jericho hospitals.
The Beginning of Clinical Teaching
Clinical teaching in the new hospital was expected to begin in 1957 after inspection by the University of London. This development helped create a stronger foundation for local medical education, specialist training, research, and public health planning in Nigeria.
Manuwa’s role in this development placed him within one of the most important transitions in Nigerian medical history. Before institutions such as University College Hospital, Ibadan, became fully established, Nigerian medical training depended heavily on overseas qualifications and colonial medical structures.
Public Service Beyond Administration
His later public service extended beyond ordinary medical administration. He became associated with professional organisations and public bodies in Nigeria and beyond West Africa, reflecting the respect he had earned across medical and public life.
Professional Recognition
Manuwa was elected a Fellow of the Royal College of Physicians of Edinburgh in 1960 and was knighted for his contribution to medicine. These honours reflected both his professional standing and the wider recognition of his service.

His Final Years
Sir Samuel Manuwa died on 16 September 1975. By the time of his death, he had become one of the defining names in Nigerian medical history. His life had moved from colonial medical service to national medical leadership.
Manuwa’s achievement was complex and historically valuable. He worked within a colonial system, rose through its ranks, and helped prepare the ground for Nigerian leadership within medicine. His success came through professional excellence and reflected the changing political atmosphere of late colonial Nigeria.
He belonged to a generation that helped shift Nigeria from dependence on expatriate officials towards local professional leadership. His career showed that Nigerians could not only practise medicine at the highest level, but also direct medical policy, advise government, support teaching hospitals, and shape national healthcare institutions.
A Lasting Legacy
Sir Samuel Manuwa’s legacy remains powerful because it connects medical skill with institutional change. He was a surgeon, an inventor, an administrator, and a public servant. He helped make visible a future in which Nigerian medicine could be led by Nigerians themselves.
Author’s Note
Sir Samuel Manuwa’s story is a reminder that the making of modern Nigerian medicine was shaped by men and women whose skill and service challenged the limits placed before them. His career moved from the operating theatre to the highest levels of medical administration, showing how professional excellence could become a force for national change. He remains one of the key figures in the history of Nigerian healthcare because his life helped bridge the gap between colonial medical control and Nigerian medical leadership.
