Neil Hamilton Fairley KBE FRCP FRS (1891–1966): An outstanding tropical physician in the twentieth century

In the late nineteenth and early twentieth centuries, British physicians led the way in tropical medicine research. Several years later scientific advances had slowed, and Fairley’s numerous contributions were thus most welcome. Neil Hamilton Fairley was born of Scottish parents at Victoria, Australia. After qualification at Melbourne, he joined the Australian Army Medical Service (AAMS) and after several minor research projects, made valuable contributions to the understanding of tropical sprue at Bombay (now Mumbai), India. However, Fairley’s major researches were carried out during World War II (1939-45). Together with J S K Boyd he demonstrated the great value of sulphaguanidine in bacillary dysentery. Working in northern Australia and the south-Pacific region, he both contributed to elucidation of the Plasmodium vivax life-cycle, and more importantly demonstrated the value of alternative anti-malarial compounds to quinine (which was not readily available). Back in London after the war, Fairley briefly occupied the Wellcome Chair of Tropical Medicine, strongly supported London’s clinical tropical medicine, and was subsequently knighted in 1950.
