The University of North Carolina Herbarium (NCU) has catalogued only about half a dozen specimens collected by Don E. Eyles. They were collected in 1940 and 1941, and about half were collected with Mary S. Eyles.  Eyles was by profession a parasitologist, but was a serious student of ornithology and botany.

Don Eyles was born 4 September 1915 to Francis L. and Mory A. Eyles. The 1920 US Federal Census lists the Eyles family as living in Atlanta, Georgia, and consisting of parents Francis L. (age 37), Mory A. (35), Francis L. (11), Don E. (4), and Ruth (1 month).

Don Eyles died on 4 October, 1963, and was buried in Arlington National Cemetery (Section 35, Site 2147) in Virginia.

Dr. Don E. Eyles died on October 4, 1963, of coronary thrombosis on board ship in Penang, Malaysia, a few hours before he and his family were due to return to the United States. This sudden death of an outstanding scientist and excellent colleague was particularly tragic, as Dr. Eyles was about to retire after twenty-four years' work for the U.S. Public Health Service to join the Lahore (Pakistan) Unit of the Institute of International Medicine of the University of Maryland School of Medicine.

Dr. Eyles was born in 1915 in Atlanta, Georgia, and obtained his M.S. (Biology) at Emory University and his Sc.D. at the Johns Hopkins University in Baltimore.

During the early period of his academic life he was interested in ornithology and medical entomology, but later much of his work was connected with investigations on malaria imported into the United States by returning Service-men, and with curative action of drugs against relapsing malaria infections. The difference between the effect of pyrimethamine and primaquine on the tissue forms of malaria parasites became clear as a result of this work. The curative action of pyrimethamine and sulphadiazine, and the synergistic effect of these drugs in toxoplasmosis, were reported by Eyles et al. in 1952, and these findings were promptly confirmed in acute and chronic forms of the disease. Much knowledge of the epidemiology of toxoplasmosis was due to the work of Eyles on the relationship between the infection in domestic animals and its transmission to man.

In 1960 Dr. Eyles, taking a clue from his accidental laboratory infection, showed that Plasmodium cynomolgi bastianellii of monkeys can be transmitted to man through a mosquito. This stared much now and still expanding research on the possibility of simian malaria as an anthropozoonosis.

In 1961 Dr. Eyles was given the task of establishing a research unit of the U.S. Public Health Service in Malaya and he went to the Far East companied by his wife and three children. The research unit was set up at the Institute for Medical Research in Kuala Lumpur and within less than three years Eyles and his Malaysian, American, British and Australian colleagues produced a remarkable series of investigations which have greatly extended our knowledge of simian malaria. Five new species of malaria parasites of Malaysian monkeys and of a moose-deer were discovered and their relationship to a number of anopheline vectors was established.

A new area for further research of considerable fundamental and practical importance was thus opened in a field that until recently seeded to be uninspiring and well-trodden. The impetus given in this was to the investigation of simian malaria was characteristic of Eyles’s vision, determination, leadership and phenomenal energy. During the past year Eyles was greatly interested in the problem of resistance of human plasmodia to synthetic drugs and particularly 4-aminoquinolines. He left a number of papers which are now awaiting publication.

Some of us who saw Eyles in September at the International Congresses of Tropical Medicine in Rio de Janeiro and who heard his summary of the work carried out in Malaya could not help saying that he seemed to be in a hurry to complete one job and to start another. He was in a hurry, indeed for this “appointment in Penang”.

Eyles’s work resulted in more than a hundred publications. He has demonstrated his qualities as an administrator of a research laboratory and his brilliance and versatility as an investigator of general and specific problems in parasitology. One of Eyles’s most important assets was his ability to work with a team; he has undoubtedly stimulated in others as much research as he has been personally responsible for. His proficiency in experimental work in parasitology was equaled by his general knowledge of ornithology, botany and entomology. He was an intensely live individual – an inveterate collector of almost anything, biological or otherwise – universally liked and admired by those who have had the good fortune to know him during his short, happy and fruitful life.
