Dr. Philip E. S. Palmer was educated in England and gained his medical and radiological training at London University. He practiced diagnostic radiology in England for 8 years and then spent the next 15 years in Africa, first as a government radiologist in Matebeleland, in the then Federation of Rhodesia and Nyasaland, and then for 4 years as Professor and Chairman of Radiology at the University of Capetown, South Africa. During those years he traveled widely, especially in Africa, visiting, lecturing, and studying at almost all of the universities south of the Sahara. He also lectured in Cairo and Alexandria in Egypt, in Ethiopia and at many of the other major African medical centers.

He was an invited speaker at conferences in Jamaica and many major American universities, usually choosing tropical diseases as his subject. In 1967 he was appointed Professor of Radiology at the University of Pennsylvania and after 2 years became the first Professor and Director of Diagnostic Radiology at the University of California, Davis, where he later became Chairman, a position he held until his retirement in 1993. He has been an invited speaker at many American universities and radiological societies, the American Society of Tropical Medicine, the AFIP, and many universities and international and national meetings in different parts of the world.

Dr. Palmer was appointed more than 30 years ago as an Advisor and Consultant to the World Health Organization Headquarters in Geneva, Switzerland. Since then he has often been asked to advise and teach in small and large hospitals and medical centers in the Pacific and Southeast Asian, European, African, Eastern Mediterranean (Middle East), and American Regions of the WHO. He has chaired or been a member of numerous WHO Expert committees and is editor, senior author, or co-author of the popular WHO Manuals of Ultrasound, Radiological Interpretation, Darkroom Technique, and Radiographic Technique. These are available world-wide in more than 11 languages. He was for many years a member of the International Education Committees of both the International Society of Radiology and the Radiological Society of North America. He spent sabbatical years working and teaching in East and Southern Africa. He has been an examiner for the specialist degrees in Radiology for universities and colleges in West, East, and South Africa, as well as being an editor, guest editor, or reviewer for several journals. His publications include more than 220 articles in peer-reviewed journals, numerous textbook chapters, including contributions to textbooks of tropical diseases and parasitology. Dr. Palmer is an elected Honorary Fellow of the Romanian Society of Radiology and Nuclear Medicine, and of the West African and East African Radiological Societies. In 1993 he received the German International Roentgen Award (Roentgen Plakette) and in 1996 was the first Antoine Beclere Lecturer of the International Society of Radiology at their meeting in Beijing China.

Dr. Palmer is currently Emeritus Professor of Radiology at the University of California, Davis, and continues to be an Advisor to the World Health Organization.

In 2000 the President of the Radiological Society of North America honored him with a Special Presidential Award for his 'Significant Contributions to the field of Radiology and the Radiological Sciences'.


Dr. Maurice M. Reeder was educated at Loyola High School and College and the University of Maryland School of Medicine in Baltimore, and then spent 20 years as a career officer (Colonel) in the U.S. Army Medical Corps. He has worked as a radiologist in East Asia for 3 years, and for 3 years was a staff radiologist at the Registry of Radiologic Pathology at the Armed Forces Institute of Pathology in Washington, D.C. There he began to assemble what has become a vast collection of radiological and pathological material on tropical diseases, contributed by military and civilian radiologists from all over the world. There are currently over 5000 images of tropical diseases covering more than 50 diseases in this collection. He has lectured and written extensively on this subject, and has become well known as an expert in all aspects of tropical imaging. He has visited and taught in South America, Mexico, Canada, the Caribbean, Europe and Asia and has had continuing experience in tropical diseases as Chief of the Department of Radiology at the Walter Reed Army Medical Center and Radiology Consultant to the Army Surgeon General from 1972 to 1977 and as Chairman of the Department of Radiology at the University of Hawaii School of Medicine and Radiology Consultant at Tripler Army Medical Center in Honolulu from 1978 to 1997.

While an Adjunct Professor of Radiology at the Uniformed Services University of the Health Sciences in Bethesda, Maryland, he developed a permanent collection of Tropical Imaging for the U.S. Military with the 10,000 image Reeder and Palmer collection as its core. In the process, he founded the International Registry of Tropical Imaging (IRTI) housed at USUHS and served as its first Registrar. He has recently overseen the development of this DVD and an internet website at USUHS and the ACR based on "The Imaging of Tropical Diseases" text, with the kind permission of the publisher, Springer-Verlag Heidelberg Berlin New York.

Dr. Reeder is a Fellow of the American College of Radiology and a member of seven other Radiological and Tropical Disease Societies. He is the author of Reeder and Felson's "Gamuts in Radiology" (4 editions, 2 CD-ROMs and 3 spinoffs) and of over 60 journal articles and book-chapters. He has lectured at over 225 universities, meetings, and conferences in different parts of the world, and has been the founder and course director for 20 Masters Diagnostic Radiology Conferences held in Hawaii and Europe prior to 2000.


Born in Canada, where he spent his early years, Dr. Daniel H. Connor graduated from Queen's University, receiving his M.D., C.M. in 1953. He trained at Emergency Hospital (now Washington Hospital Center) and did his residency training in pathology at Emergency Hospital and George Washington University. He served in the US Army as Chief, Laboratory Service at Irwin Army Hospital and the 47th Field Evacuation Hospital. On leaving the Army he joined the permanent civilian staff of the Armed Forces Institute of Pathology, becoming Chairman, Department of Infectious and Parasitic Diseases and Registrar, Registry of Geographic Pathology in 1970. He continued in these positions until his retirement from Federal Service in 1987. Beginning in January 1988, he was a Visiting Professor, Department of Pathology at Georgetown University until his retirement in 2001.

Dr. Connor's research interests have focused on infectious, parasitic, and tropical diseases. In pursuing these interests he has lived in tropical Africa for 5 years while studying onchocerciasis, buruli ulcer, endomyocardial fibrosis, and other diseases of the African hinterland. He has authored and coauthored 180 published papers and a variety of chapters for textbooks, and he co-authored and co-edited two definitive texts - Pathology of Tropical and Extraordinary Diseases (American Registry of Pathology, 1976) and Pathology of Infectious Diseases (Appleton & Lange 1997). He has served the World Health Organization as a consultant, temporary advisor, and as a member of various expert committees and scientific working groups. He served also the American Board of Pathology from 1972 through 1981, first as a consultant and then as a member of the test committee on medical microbiology, and he continues to serve the board as consultant. Other services include Chairman, U.S. National Committee, International Council of Societies of Pathology, and the editorial boards of two peer-reviewed internationally orientated scientific journals.

Teaching has played a prominent role in his career. He has trained research fellows supported by the World Health Organization and the Pan American Health Organization as well as civilian consultants and scientists on sabbatical leave. These include Deans, Chairmen and distinguished scientists in Western countries, Asia, and Africa. At Georgetown University he received the best teaching award three times.


Ian J. Dunn became interested in tropical diseases while he was an undergraduate studying zoology at the University of British Columbia. In 1979 he went to graduate school at the University of Toronto, at first in the Masters course, then to complete his PhD in Parasitology in 1984.

Stimulated by his lecturers, he became interested in teaching and, while studying Diagnostic Parasitology, worked in the Tropical Disease Unit of the Toronto General Hospital. There he joined clinical teaching rounds in tropical medicine and gave laboratory courses at the University of Toronto.

He gained his medical degree from the University of Calgary and at the same time took a postdoctoral fellowship in intestinal physiology in the Intestinal Disease Research Unit. In 1986/1987 he was awarded a Health-Exchange Scholarship, which allowed him to study tropical diseases at the internationally recognized Christian Medical College in Vellore, India. He also spent time at Tribhuvan University in Kathmandu, Nepal and was able to visit a rural hospital in Pokhara. His scholarship travels ended at the Hospital for Tropical Diseases in Bangkok.

His radiology training was at the Dalhousie University in Halifax, Nova Scotia, and was followed by a Fellowship in abdominal imaging and intervention at the University of British Columbia, with additional training in angiography and cardiac imaging at the University of Toronto.

He is currently a Clinical Assistant Professor in the Radiology Department of the University of British Columbia and a consultant radiologist in Vancouver. He continues to write on parasitology and imaging. .
