Death of Professor Yasunosuke Suzuki August 8, 2011It is with great sadness that the Collegium Ramazzini informs its Fellows of the death of one of its most illustrious and beloved colleagues, Professor Yasunosuke Suzuki. Professor Suzuki was an influential member of the Collegium and was honored with the Ramazzini Award in 1993 for his contribution to the scientific knowledge on the pathology of mesotheliomas among asbestos-exposed workers. Upon his retirement from the Mount Sinai School of Medicine in 2006, the Collegium Ramazzini again honored Professor Suzuki with the Irving J. Selikoff Award to recognize his many years of work as a pathologist who meticulously studied the diseases caused by asbestos and who also ventured forth courageously from his laboratory, as a true follower of Ramazzini and Selikoff, to press the urgent need in nations around the world for the banning of all production and use of all forms of asbestos. In fact, Dr Suzuki played a critical role in the decision by the Government of Japan to ban all use of asbestos in Japan.
Collegium Ramazzini President Philip Landrigan remembers the occasion of the Selikoff award noting "(It) was a bittersweet occasion. Dr. Suzuki served as a member of the faculty of the Department of Community and Preventive Medicine at Mount Sinai for 40 years. While there are many of us still at Mount Sinai who worked with Dr. Selikoff as junior faculty, students and trainees, Dr. Suzuki is the last member of the "Selikoff generation" the group of age peers who worked most closely with Dr. Selikoff for so many years in Dr. Selikoff's pioneering studies of other asbestos and other occupational hazards."
Professor Suzuki received his M.D. degree from the Keio University School of Medicine in Tokyo in 1953. He completed one year internship in Tokyo at the Setagaya National Hospital, and was licensed in 1954 by the Japanese Government.
In 1954 he joined the Department of Pathology in the Keio University School of Medicine starting as an "Assistant of Pathology". Dr. Suzuki's early work on the kidney he proved the presence of the mesangium, the third structural element of renal glomerulus. Working with new technology - the electron microscope, he was able to further define the structure of the mesangium.
In 1959, he was awarded the Doctorate of Medical Sciences in the field of Pathology. In 1960 he was sent abroad as an International Post Doctoral Research Fellow at the U.S. National Institutes of Health (NIH) training at New York University School of Medicine under Professor Johannes Rhodin. In 1961 he trained at the Mount Sinai Hospital Renal Pathology Division under Dr. Churg. He returned to Keio University 1962 as a faculty member. In 1966, Dr. Suzuki was invited to re-join Mount Sinai as a Research Associate. In addition to renal pathology with Dr. Churg, he started to investigate pathology of asbestos related diseases with Dr. Dr. Irving J. Selikoff.
The research on asbestos related diseases included seminal work on pulmonary asbestosis, the development and formation of asbestos bodies and electron microscopy of human malignant mesothelioma. In 1973, Dr. Suzuki again returned to Japan to serve as Chairman and Professor of Anatomy at Fujita-Gakuen University School of Medicine.
He returned to Mount Sinai in 1975 as Research Professor of Community Medicine and Research Associate Professor of Pathology. For the next 31 years, from 1975 to 2006, he devoted his time solely to the investigating the pathology of asbestos related diseases. One of his most significant contributions was providing support to Selikoff's ground-breaking epidemiological study on asbestos insulation workers. Slide by slide, he reviewed the pathologic autopsy and biopsy samples taken from approximately 5,000 cases of insulation workers and confirmed the diagnosis of asbestos related diseases.
He was promoted to Professor of Pathology in 1989 and in 1991 to Professor of Community and Preventive Medicine.
Dr. Suzuki published 171 peer review scientific papers. Dr. Suzuki estimated that over the course of his career in research, he had examined and written up approximately 538,000 individual slides.
Suzuki received several honors in addition to those conferred by the Collegium Ramazzini. Other awards include the honorary title of Guest Professor at Tokai University School of Medicine (1993-1996) and Honorary Visiting Professor of Pathology at Keio University School of Medicine (1999-2000).
