Jean-Marie Friedt - 1940-2008
It is with deepest sadness that the French Group of Mössbauer Spectroscopy announces the passing of Dr Jean-Marie Friedt in November 2008.
Jean-Marie Friedt, who was born in 1940, graduated in Strasbourg, France, with a degree in engineering. As a volunteer to non-active military service, Jean-Marie went to Brazil (the Centro Brasileiro de Pesquisas Físicas, or CBPF, in Rio de Janeiro) and then joined Centre National de la Recherche Scientifique (CNRS) as a researcher, returning to the Nuclear Research Centre of Strasbourg-Cronenbourg, where he worked until 1986. He received his Ph.D. degree in 1969 from the University of Strasbourg, with a thesis devoted to "Mössbauer spectrometry of Fe from electronic capture of 57Co in cobalt alloys." While at CNRS, Jean-Marie was awarded the CNRS Bronze Medal.
Jean-Marie developed a Mössbauer laboratory with wide experimental facilities, giving rise to various isotopes including rare earth and actinides (57Fe, 119Sn, 151Eu, 121Sb, 129I, 161Dy, 155Gd, 169Er, 170Yb, 197Au, 231Pa, and 237Np). The main topics were oriented to metallurgy, disordered solid states (oxide glasses, rare earth-based metglasses, spin glasses), magnetism of rare earth and actinide systems, and density of charge and of spin in insulating and conducting systems. Jean-Marie and his coworkers, including Jean-Pierre Sanchez and Marc Maurer, worked in collaboration with different French institutes (including the Recherche sur la catalyse in Lyon, Curie in Paris, CEA in Saclay, and ENSC and Le Bel in Strasbourg) and also internationally, including researchers at the Technical University of Munich (M. Kalvius, F. Wagner, and J. Litterst), Bochum University (H. Micklitz), Kyoto University (T. Shinjo), the CBPF in Rio de Janeiro (J. Danon and E. Baggio-Saitovitch), and the Nuclear Physics Institute and the University of Krakow (A. Hrynkiewicz and K. Tomala).
His scientific activities are recognized through about 80 publications and book chapters, and he was a very active member of the French Group of Mössbauer spectroscopy during the 1980s.
Jean-Marie was invited for long stays at Argonne National Laboratory in the United States and in Munich, and many scientists were his guests at Strasbourg in the frame of international bilateral scientific agreements, among them J. Danon, G. Shenoy, H. Micklitz, J. Litterst, A. Hrynkiewicz, M. Pasternak, and A. Vasquez.
After 1986, Jean-Marie moved from CNRS to the Air Liquide Company, first in Paris and then in Japan, where he became the Manager of the Technological Development.
Our thoughts are with his family.
