An award given to a scientist for distinguished research in radio propagation & the development of satellite technology.
The International Union of Radio Science (Union Radio-Scientifique Internationale), based in Belgium, is a non-governmental and non-profit organization under the International Council for Science responsible for stimulating and co-ordinating, on an international basis, studies, research, applications, scientific exchange, and communication in the fields of radio science. The John Howard Dellinger Gold Medal is one of the awards URSI presents for distinguished research in radio science (Ref. 1) . John Chapman was the recipient of a number of awards and honours for his work in aero-space technology: 1966 - the Royal Society of Canada/ 1966 - the Engineering Medal of the Association of Professional Engineers of Ontario (2006.0011)/ 1966 - the Dellinger Gold Medal of the International Union of Radio Scientists (2006.0007)/ 1966 - the McCurdy award from the Canadian Aeronautics and Space Institute (2006.0008)/ 1967/68 - the Charles Chree Medal and Prize of the Physical Society & Institute of Physics (2006.0009)/ 1977 - Canada's Queen Elizabeth II Silver Jubilee Medal (2006.0010)/ 1979 - the McNaughton Medal of the Institute of Electrical and Electronics Engineering, Canada (2006.0006)/ 2005 - inducted into Canada's Telecommunications Hall of Fame as a pioneer (2006.0005) in the Servants of the Public category (Refs. 2-5).
John Chapman (1921-1979) from London, Ontario was a pioneer in Canadian telecommunications and a researcher, innovator and leader of the Canadian space program whose work set a course for the Canadian space industry which is still being followed today. From 1949 to 1968 Chapman was scientist, superintendent and deputy chief superintendent in the Defense Research Telecommunications Establishment in Ottawa and then assistant deputy minister for research in the federal Department of Communications. From 1958 to 1971 Chapman played a key role in initiating and directing the successful Alouette/IS scientific Earth satellite program. In 1966 he was appointed chairman of a government study group to examine the upper atmosphere and space programs in Canada. The resulting report was a landmark contribution to space policies and plans in Canada and led to the redirection of Canada's space program from scientific to applications satellites. Chapman was also the prime mover behind Canada's co-operative program with NASA and the European Space Agency to design, build and demonstrate the Hermes Communications Technology Satellite which would provide Canadians in remote areas with direct-to-home television by satellite. Chapman was a member of the Royal Society of Canada. He was also part of the National Research Council (NRC) Associate committee on Space Research, a council of the top Canadian space scientists. He also served on the International Union of Radio Science and the American Geophysical Union. In the1990's the headquarters of the Canadian Space Agency was renamed the John H. Chapman Space Centre to commemorate Chapman's accomplishments in the space industry. Since 2000, the Canadian Space Agency has awarded the John H. Chapman Award of Excellence to celebrate remarkable contributions to the advancement of the Canadian Space Program & a lifetime of achievement in space science and technology (Refs. 2-5.
