From East African fieldwork to Cambridge
Thomas Risley Odhiambo was born in Mombasa, Kenya, on 4 February 1931. He attended Maseno School and studied botany and zoology at Makerere University College in Uganda. Agricultural research work followed in Kenya and Uganda. It brought him into contact with insects as subjects of classification and as practical problems for growers.
His early work identified new genera and species of East African Miridae bugs. That taxonomic research preceded the laboratory physiology for which he became better known. At Cambridge he completed a PhD in insect physiology in 1965 under Vincent Wigglesworth. The shift from describing insects to investigating their internal regulation broadened his research without removing its foundations in careful observation.
Testing the effects of an insect hormone
Odhiambo’s 1965 Nature communication investigated the corpus allatum hormone in the desert locust, Schistocerca gregaria. The question concerned the relationship between a hormone associated with reproductive development and the insect’s energy stores. This placed his work within an existing experimental debate, rather than making him the discoverer of insect hormones.
A fuller 1966 study examined spontaneous movement in adult male locusts. Removing the corpora allata produced persistent inactivity; implanting active glands could reverse it. Removing the reproductive organs did not produce the same effect. He proposed that the hormone influenced movement through the central nervous system and that reduced movement helped explain accumulated fat and glycogen. The proposed mechanism was an interpretation of the experiments, not a demonstrated universal rule for every insect.
Reproduction as a research problem
His research also examined the accessory reproductive glands of male desert locusts. A 1969 paper used microscopic and chemical staining techniques to distinguish nine gland types by their cells and secretions. The work linked anatomical structure to the different materials produced during reproduction, rather than treating all of the glands as interchangeable.
Tsetse flies raised another problem: a female retains her offspring as it develops from egg to larva. In a 1971 study of Glossina pallidipes, Odhiambo separated egg development from ovulation. Virgin females could mature eggs, but mating was needed to initiate ovulation. That distinction gave a specific experimental account of reproductive regulation. It also shows the substance of his scientific work beyond his better-known leadership of a research centre.
Research institutions for problems in Africa
After returning to Kenya he joined zoology at the University of Nairobi. His 1967 Science article, East Africa: Science for Development, argued for research capacity relevant to the region’s needs. icipe’s institutional history connects that argument with agricultural production, vector-borne disease and training African researchers.
The International Centre of Insect Physiology and Ecology opened in 1970. Odhiambo’s founding leadership worked alongside Carl Djerassi and supporters in national science academies. The institution sought to bring strong fundamental research into contact with practical questions about insects and livelihoods. Its later programmes and discoveries belong to successive teams; they should not all be assigned retrospectively to its founding director.

Building a wider scientific public
Odhiambo helped create scientific networks beyond icipe. He was a founding fellow of the Third World Academy of Sciences, now the World Academy of Sciences, in 1983 and became the first president of the African Academy of Sciences, established in 1985. These organisations aimed to recognise researchers, support scientific work and strengthen institutions across national borders.
Publishing formed part of that effort. An African Academy case study describes the development of scholarly publishing and production capacity in Nairobi. TWAS’s memorial also records Odhiambo’s interest in books for children and in bringing scientists into discussion with political leaders. Such activities addressed the conditions in which research could circulate, gain support and become part of public life.
A scientific and institutional legacy
Odhiambo died in Nairobi on 26 May 2003. Contemporary scientific memorials remembered both his experimental work and his efforts to build African research capacity. Those dimensions reinforce each other: his argument for institutions came from experience of conducting research, while the institutions enabled other scientists to pursue problems he could not solve alone.
His career is therefore best followed through particular contributions: identifying insects, testing hormonal effects in locusts, investigating reproduction and creating settings for collaborative research. It offers a concrete account of scientific leadership, in which laboratory results, training, publishing and institutional negotiation each require their own evidence and their own share of credit.

Contemporary memorial is useful for TWAS membership, public communication and children’s books. Its printed/OCR AAS date of 1995 conflicts with the 1985 academy record and National Academies history; 1995 is rejected. Director-retirement dates also vary, so the draft does not assert an exact final year.
