Dr. René Bovey
Dr René Bovey passed away on 13 March 2018 in his 99th year. Our organisation lost its prominent founder member and a wise and rigorous first secretary. René Bovey got his degrees at the University of Lausanne and begun his scientific career in England before joining in 1951 the Federal Agricultural Research Station of Changins, Switzerland where he developed plant virology and electron microscopy. From 1959 until his retirement in 1984 he directed the Plant Protection department. He greatly contributed to the development of the Institute and regional plant protection services, besides being an associated professor at the University of Lausanne. He introduced schemes for the production of healthy plant propagation material with a particular focus on viral diseases of grapevine and fruit trees. He authored hundreds of scientific and popularized publications. His academically prized contributions to the editing of journals and books such as “La Défence des plantes cultivées” or “Virus and Virus-like Diseases of Grapevines” are only part of his legacy to the international scientific community and farmers. The unique bibliographic compilations remain invaluable for ICVG. His warm personality, classical education, open mind and deep interest in sciences made of René Bovey a most recognized and respected leader, colleague and friend.

Dr. Antoine Caudwell
Dr. Antoine Caudwell passed away in 2019 at the age of 91. After graduating from an agriculture school, he worked shortly on barley genetics at the French National Research Institute for Agriculture or Institut National de la Recherche Agronomique (INRA) in Versailles. Then he investigated the nature of flavescence dorée at INRA in Bordeaux in the late 1950s. This newly emerging disease was devasting vineyards of the Gascogne region in the southwest of France. Based on his research on the biology and epidemiology of flavescence dorée, A ntoine Caudwell earned a PhD from the University of Poitiers in 1965. Next, he integrated INRA at Colmar where he identified herbaceous hosts of the phytoplasma causing flavescence dorée -currently named Candidatus Phytoplasma vitis- and demonstrated its transmissibility to broad beans. In 1972, he transferred to INRA in Dijon where he established a phytoplasma laboratory. Antoine Caudwell pioneered research on grapevine phytoplasma diseases such as flavescence dorée and bois noir. His work primarily focused on phytoplasma-host and phytoplasma-leafhopper vector relationships and the development of serological diagnostic assays for phytoplasmas. He published many articles in scientific and trade journals. Antoine Caudwell retired from INRA in 1993. He attended numerous ICVG meetings, contributed several literature reports on graft-transmissible agents of grapevines that were appreciated by ICVG members and served on the ICVG Steering Committee for many years.
William Boright Hewitt
William "Bill" Hewitt was born July 17, 1908 in Fayetteville, Arkansas, and died in Sequim, Washington, on July 3, 1998.
Hewitt had a life-long association with the University of California at Davis. He finished his BS in pomology (1933), his MS in pomology (1934) and his PhD in plant pathology (1936). In 1937, Bill joined the Department of Plant Pathology at Davis. He served the department as chairman from 1968 to 1969. In 1969 he was appointed director of the San Joaquin Valley Agricultural Research and Extension Center, Parlier. He held this position until his retirement in 1974. During his tenure at Davis, he contributed greatly to the strength and international reputation of his department.
Professor Hewitt had an active research program and worked with a spectrum of pathogens and hosts. He published over 100 papers on his own research. His primary interest was in the etiology, epidemiology and control of diseases of the grapevine. He is known especially for the separation and identification of several viruses in grapevines and is called the father of modern grapevine virology. He was instrumental in establishing the International Council for Study of Viruses and Virus Diseases of the Grapevine and he served as its president for six years. He was deeply concerned with control of these viruses and developed protocols for detecting virus-infected plants as well as methods for eradicating viruses from these plants by thermotherapy. These virus-free plants were made available to the industry through what is now the Foundation Plant Services. He also directed a similar program by which foreign vines could be imported under federal quarantine. These activities attracted numerous visitors as well as providing many opportunities for him to travel and advise on the establishment of similar clean stock programs around the world. His curiosity about soil-borne grapevine viruses led to the identification of nematodes as vectors of plant viruses with colleagues Raski and Goheen in 1958. This research earned them the Ruth Allen Award from the American Phytopathological Society. Bill was the recipient of a number recognitions and awards throughout his career. He also served in leadership positions in the American Phytopathological Society and as a member of numerous committees at the departmental, college and campus level.
Professor Hewitt taught undergraduate and graduate classes between 1949 and 1968 and served the department as graduate advisor from 1960 to 1968. He demonstrated his faith in his department and in graduate education by establishing the W. B. Hewitt scholarship for graduate students in the Department of Plant Pathology upon his death.

Giovanni Paolo Martelli
Giovanni Paolo Martelli, President of the International Council for the Study of Viruses and Virus Diseases of the Grapevine (ICVG) from 1987 to 2018, passed away on January 8, 2020 at the age of 84. He dedicated his long-lasting academic and scientific career to the advancement of knowledge, contributing outstanding achievements in plant virology, with a relentless commitment and generous vision.
In 1956, he graduated cum laude in Agricultural Sciences from the University of Bari, where he spent most of his career. At Bari, he established a plant virology laboratory which soon became one of the leading units in Italy and remains internationally renowned to this day. Martelli investigated viruses and virus diseases of Mediterranean crops and was a recognized authority on viruses and virus diseases of grapevines. He co-authored the description of more than 50 new virus species, genera and families, and characterized many other viruses. In the late 1980s, Martelli set up a biotechnological research unit for plant virus diagnostics based on the use of recombinant DNA and monoclonal antibodies. He also established a unit for the sanitation of grapevines and fruit trees, and the production of virus disease-free material, and was active in the planning and implementation of plant certification programs. Martelli was an active member of the International Committee on Taxonomy of Viruses (ICTV) since 1978. In the recent extension of the virus taxonomy structure to 15 ranks, the name "Martellivirales" was ratified by ICTV to acknowledge Professor Martelli's outstanding contribution to plant virology and virus taxonomy. Professor Martelli published more than 300 research papers in international refereed journals and many additional written contributions for a total over 600 scripts, including six books. He served on many esteemed virology committees and was awarded numerous prizes, among which the "F. Maseri-Florio World Prize for Distinguished Research in Agriculture." Professor Martelli served as an associate editor of Phytopathology, European Journal of Plant Pathology and Vitis. Since 2002, he was the Editor-in-Chief of the Journal of Plant Pathology.
Giovanni Paolo Martelli will be always remembered as an excellent scientist and a pioneer with a broad, far-sighted vision. He was an exceptional mentor and a guide for his coworkers, always open to challenging discussions, and invariably listening to different opinions and to sharing of ideas and thoughts for maintaining his scientific curiosity. He passionately thought, practiced and defended rigorous, honest and high-quality research. His passing is a great loss for those who had the honor and privilege of working with him and benefited from his constant support and help.
