Howe: A Biography".




Bertrand L. Goldschmidt

         Dr. Bertrand Goldschmidt, born in Paris in 1912, was the last personal assistant of Marie Curie who engaged him in 1933 (the year before her death) at the Radium Institute where he got his Ph.D. and worked until 1940.

During the war, he participated in the atomic projects in North America as a member of the British team to which he had been seconded by the Free French.   He worked in Glenn Seaborg's group on plutonium extraction at Chicago during the summer of 1942.   Then he joined the Anglo-Canadian project, from its beginning at Montreal, as section leader of the Chemistry Division, which he directed in Chalk River before returning to France in 1946.

         One of the founders of the French Atomic Energy Commission in 1946, he was in charge of its Chemistry Division until 1960 and of its International Relations Division until his retirement.   Bertrand Goldschmidt is noted for his expertise in the chemistry of radioactive elements, the extraction of plutonium and the metallurgy of uranium.   He is the author of a number of books on the history of the development of nuclear technology, the latest being "Pionniers de l'Atome".

         Co-Laureate of the "Atoms for Peace" Award in 1967, he was the French Governor on the Board of the International Atomic Energy Agency from 1958 to 1980 and Chairman of this Board in 1980.




Leslie G. Cook

        Born in Paris, Ontario in 1914 and educated at the University of Toronto, the University of Berlin and Cambridge University, Leslie Cook has had a distinguished career as a chemist and energy analyst.   He has held positions of Research Chemist and Manager of Physics Research at the Aluminium Research Laboratories of the Aluminium Company of Canada; Director of Research of the Chemistry & Metallurgy Division of Atomic Energy of Canada; Manager of Research Program Planning at the General Electric Research Laboratory in Schenectady; Vice-President for Research Programs at the National Research Council of Canada, and Manager of Research Planning for Exxon Corporate Research in Linden, New Jersey.   Dr. Cook now owns the consulting firm of L.G. Cook Associates in New Jersey and continues his enjoyment for music and piano.   He brings to the Special Symposium the unique perspective of one who was in Otto Hahn's laboratory in 1936-1938 during the time that fission was discovered.




Geoffrey C. Hanna

        Born in Stretford, Lancashire, England in 1920, Geoff Hanna was educated at Cambridge University.   He started his career as a physicist working on radar development during the Second World War with the British Ministry of Supply and came to Canada in 1945 as part of the United Kingdom mission first in Montreal and later at the Chalk River laboratories.   He joined the staff at Chalk River in 1950.   Geoff Hanna has had a distinguished career in nuclear physics where he is an authority on alpha radioactivity; ionization from the slowing down of particles ranging from electrons to fission fragments; nuclear fission; and on neutron cross section measurements.   He is noted for his development of instrumentation in particular the multi-channel pulse height analyzer.   Since 1962 he has shouldered an increasing administrative load as Head of Nuclear Physics, Director of Physics Division and Director of Research at the Chalk River Nuclear Laboratories.   In addition to these duties Dr. Hanna has played an active role in the funding of physics in universities through Canadian funding agencies.   Geoff Hanna is a fellow of the Royal Society of Canada, has an honorary D.Sc. from McGill University, and has been president of the Canadian Association of Physicists.   Now officially retired, Geoff continues as an advisor for Canadian physics.




Alvin M. Weinberg

        Alvin M. Weinberg joined the original group that developed the first chain reactors at the University of Chicago in 1941.   He has since been a leading figure in the development of nuclear energy: among his accomplishments was the proposal to use pressurized water reactors for nuclear submarine propulsion.   He served as Research Director and then Director of the Oak Ridge National Laboratory from 1948 to 1973.   In 1974 he was Director of the Office of Energy Research & Development in the Federal Energy Administration.   From 1975 to 1985 he was the Director of the Institute for Energy Analysis of the Oak Ridge Associated Universities.   He is now a Distinguished Fellow at the Institute.

        Alvin Weinberg, a native Chicagoan, received his B.S., M.S., and Ph.D. degrees in physics at the University of Chicago.   He collaborated with Eugene Wigner to write the standard book on nuclear reactor theory, "The Physical Theory of Neutron Chain Reactors".   In addition to his strictly scientific and administrative work, he has been a prolific writer on the interaction between modern technology and society.   Characteristic of these writings has been his coining of phrases that have become part of our everyday language: "Big Science", "Technological Fix", and "Faustian Bargain" are words that have flowed from his pen.   Many of his early essays were published in 1967 in a collection entitled "Reflections on Big Science".

        For his contributions to the development of nuclear energy, Alvin Weinberg has received the Atoms for Peace Award, the Harvey Prize, the Heinrich Hertz Award, and the Fermi Award.   He is a member of the National Academy of Sciences, the National Academy of Engineering, the American Academy of Arts & Sciences, the American Philosophical Society, and a Foreign Member of the Royal Netherlands Academy of Sciences.

        Dr. Weinberg lives in Oak Ridge, Tennessee with his wife Gene.   When not engaged in his scientific work, he can usually be found playing the piano or perfecting his backhand on the tennis court.




John S. Foster

        John Foster was educated at Dalhousie University and the Technical University of Nova Scotia, graduating with degrees in Mechanical and Electrical Engineering.   He served as an engineering officer in the Canadian Navy during World War II and was later with Montreal Engineering as a design and field engineer on thermal power plant projects in Canada and Latin America.

        In 1954, John Foster became a member of the team that performed the conceptual studies for NPD, Canada's first nuclear power plant, and for the next 20 years headed engineering and project management for CANDU nuclear power plants in Canada and abroad.   He was also responsible for the first phase of the Bruce Heavy Water plant and the Nelson River HVDC Transmission Facilities.   He was President of Atomic Energy of Canada Limited from 1974 to 1977.   He returned to Monenco in 1978 and was a Vice-President of Monenco Companies until 1983, when he retired.

        Dr. Foster served on the Council of the Association of Professional Engineers of Ontario from 1970 to 1973.   He was a member of the Executive Committee of the Canadian Nuclear Association for several years and Chairman in 1980.

        Dr. Foster has long been active in the World Energy Conference.   A member of the Executive Committee of the Canadian National Committee for many years, he was Chairman from 1979 to 1982.   He was Vice-Chairman of the Conservation Commission and Chairman of the Program Committee before election this year to the office of Chairman of the International Executive Council, the first Canadian to be so honoured.

        Dr. Foster has honorary degrees from the Technical University of Nova Scotia and Carleton University and is the recipient of the W.B. Lewis Medal from the Canadian Nuclear Association, the Gold Medal of the Association of Professional Engineers of Ontario and the Julian C. Smith Medal of the Engineering Institute of Canada.   He is a Fellow of the Royal Society of Canada, the Canadian Academy of Engineers and the Engineering Institute of Canada.




Sylvia Olga Fedoruk
