Prof Alexander John Haddow CMG FRS FRSE FRCPSG FRES (27 December 1912 – 26 December 1978).
FRS CMG was a Scottish entomologist recognised for his work at the Uganda Virus Research Institute, including the discovery of the Zika virus, and research into the insect vectors of the yellow fever virus.
Other notable work included relating the incidence of Burkitt's lymphoma to climatic conditions and the discovery of several previously unknown viruses in east Africa, particularly arboviruses.
Haddow spent most of his research career in Uganda, where he pioneered a method for studying the prevalence and habits of biting insects (particularly mosquitoes) known as the 24-hour catch.
In 1953, Haddow was appointed the Director of the Institute and he remained in this position until his return to the University of Glasgow in 1965, where he took up largely administrative posts for the remainder of his career.
