Other notable work included relating the incidence of Burkitt's lymphoma to climatic conditions[2] 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.
[3] 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.
Caught mosquitoes were typically separated over one-hour intervals, allowing Haddow to identify the biting cycles and vertical distributions of different species.
Haddow had a keen interest in traditional Highland Bagpipe music – he was a prominent member of the Glasgow Piobaireachd Society[12] and wrote a book on the subject, published posthumously, titled The History and Structure of Ceol Mor.
[13] The University of Glasgow's Hunterian Museum also holds numerous artefacts donated by Haddow that represent his varied interests, including sketches of monkeys, game heads, ethnographic items from Uganda and archaeological finds from the Antonine Wall.
