Four PIONEERS Jany, Pierre, Claude, Jacques Olivier HARDOUIN DUPARC LSI (CNRS-CEA-X) École Polytechnique, Palaiseau IIB 2013 (Greece) 24 th June
Four PIONEERS we knew Four pioneers we knew Jany Thibault-Pénisson Pierre Delavignette Claude Goux Jacques Lévy (1947-Oct2011) (1931-Dec2011) (1925-March2012) (1937-March2012) Pioneer: someone who opens new areas of thought, of research or development
Jany Thibault (1947-28Oct2011) Born near Paris (Fontainebleau), higher education in Grenoble, PhD with Alain Bourret: High Resolution Electron Microscopy. First observations of the atomic columns of a dislocation core, in Germanium: Dislocations at atomic scale, Nature 1978 Studies of Grain Boundaries, at the atomistic level, using the Sutton-Vitek Structural Unit approach with associated core Burgers b and step h (homophase disconnections), coupled with atomistic calculations (OHD), in Ge, Si, Ni, Cu, Symmetrical TGBs and Asymmetrical TGBs Studies of interactions of GBs with crystal dislocations (plasticity), in Si, then in Cu with JP Couzinié, L. Priester, Sylvie Lartigue) Studies of metallic multilayers, of Carbon nanotubes Jany

Jany Phil Mag 2013 "For me, the most original and important results concern defects in semiconductors" Jacques Friedel in his Preface to the special P.M. issue celebrating the Career of Jany Thibault- Pénisson in the microscopy of defects and interfaces. Guest Editors: Louisette Priester, Uli Dahmen, Sylvie Lartigue, and Manfred Rühle
"Jany taught me [in 1981] to perform HREM with a pleasant smile and many useful tips. For example, never drink an espresso at lunch if you want to perform HREM in the afternoon." David Seidman (personal email 2013) (a JAP 1984) Jany, Fare Well! The many of us who kew her know how cheerful and educated (she loved painting) she was. Fare [= travel] Well, Jany!
Pierre Delavignette (1931-29Dec2011) Born near Charleroi (in Belgium), higher education in Brussels, (after the Athénée Royale of Uccle, Brussels). Pierre Theoretical Physics, Advanced Crystallography, Experimental Physics Pierre worked at Mol (SCK-CEN) with Severin Amelinckx TEM observation of dislocations in non-metallic layered structures, as tellurides, muscovite, talc, and graphite: Nature 1960 "He educated me [early 1970's] in electron microscopy. As a tutor, he was simply fantastic" Staf van Tandeloo (personal email 2013) Pierre worked on defect structures and particulary twin interfaces: twinned materials were his favourites. Pierre got invited at Caen in 1968/9 to help developments in TEM, with Robert Cadoret, Yves Monfort, Gérard Nouet,,.
Pierre Delavignette Pierre Pierre got invited at Caen in 1968/9 to help developments in TEM, with Robert Cadoret, Yves Monfort, Gérard Nouet,,. Mol - Caen - Thessaloniki connexion Gérard Nouet, Serge Hagège, Sabine Lay, Georges Bleris, Theo Karakostas, Philo Komninou, Transmission E.M., Use of Stereoprojection nets (Wulf nets) for crystal and bicrystal orientation determination (a must), Generalization of Ranganathan's CSL generating function to noncubic crystals, hexagonal, with Georges Bleris and Gérard Nouet, in parallel with Hans Grimmer in Switzerland (PSI).

Claude Goux (1925-10March2012) Claude Goux Born in Saint-Marcel (Burgundy), higher education in Paris, X 1945, + School of Mines Paris (State Corps). C. G. started to teach at the School of Mines of Saint-Étienne while doing a PhD work at the CNRS Metallurgical Chemistry Center of Studies in Vitry near Paris, under Georges Chaudron - Use of high purity aluminium (G. Chaudron's point) - Preparation of well oriented bicrystals - Observations and analyses of the bicrystals (using Georges Friedel CSL and Index formalism. No dislocations, because of G. C. ) First CRAS in 1958, 59, his PhD work in the Revue de Métallurgie in 1961 (defended in April 1962), in French (good old time). C. G. simultaneously settled a laboratory at Saint-Étienne (with many transportations from Vitry!) and created the St-Étienne group.
Claude Goux Claude Goux C. G. created the Saint-Étienne group, with brillant students: B. Baroux, J-Y. Boos, I. Herbeuval, Michel Biscondi, Jean-Bernard Guillot, Jacques Lévy, Jean Le Coze, Jean Rieu, Gilbert Hasson, who worked on several subjects, among them GB's. (including atomistic calculations) The 1975 St-Étienne Intern. Coll. on GBs in Metals, 16-20 June, organized by Michel Biscondi and Claude Goux. But after 1975, Claude Goux proved unable to keep up with the leading of his group (which survived, thanks to Biscondi et al.) "I remember him as a very cultured person" Bob Pond (email 2012) "C.G. made a great impression on me as a very honorable, sincere character, and intelligent scientific reasoning" Siegfried Hofmann

Jacques Lévy (1937-9March2012) Jacques Lévy Born in Constantine, higher education in Paris, X 1956, + School of Mines (State Corps). Named Professor at the School of Mines of Saint Étienne in 1962. One of Claude Goux's first PhD students. - Technique of thinning metallic samples for Transmission Electronic Microscopy observation of Grain Boundaries, in Aluminium, first low angles GBs, then high angle GBs. First publications in CRAS in 1966-68, in French, but old time was gone. First publication in English in 1969 (phys. stat. sol.), probably a little too late. J. L. also became an expert in metallic phase transformations and exerted more and more important positions, at Saint-Étienne and in Paris
Jacques Lévy Jacques Lévy J. L. became Director of the School of Mines of Paris, 1984-2001, and was member of several Administration Boards: École Polytechnique 1987-1994 École Normale Supérieure 1989-1997 Vice-President of Technion France 1989-1997 J. L. kept on participating to IIB's, like Minakami 1985 (4th JIM) Yoichi Ishida ( 1996) IIB89: At the School of Mines of Paris, thanks to Him (4-8 Sept.) Marc Aucouturier & Jean-Yves Laval
Jacques Bernard Lévy Jacques Lévy "I remember his humour and vigour" Bob Pond (email 2012) "He knew a lot about Science and Techniques, and also about what human scientists are, so to become an excellent director" Jean Le Coze (email 2013)
Elyseans Fields Jany, Pierre, Claude, Jacques, we wish you a good travel in the Elysean Fields, ' Ηλυσιον πεδιον, the Champs Élysées, in our Scientific Pantheon, And We will try to follow Your Scientific Excellence. All my thanks to a whole theôriâ of Collegues and Friends who helped me, and are interested in theory and praxis at interfaces. Olivier
