Jacques Lewiner is a Physicist and Inventor. He is Professor and Honorary Scientific Director of Ecole Supérieure de Physique et de Chimie Industrielles de la Ville de Paris (ESPCI ParisTech). He has filed a large number of patent applications leading to industrial development, either through licenses granted to industrial companies or through start-up companies often created with former students or researchers.

Jacques Lewiner has carried out basic and applied research in various domains of Physics. After his PhD he taught at Catholic University of America and specialized in the study of the electrical properties of solid matter. Back in France in 1968 he was first nominated Research associate with the CNRS and then in 1973 Professor in charge of the Electromagnetism Chair at ESPCI ParisTech where Georges Charpak arrived in 1980. In 1987 Pierre-Gilles de Gennes asks him to become Scientific Director of ESPCI ParisTech, a position he will keep until 2001.

His works have been devoted to electrical insulators and particularly electrets, instrumentation and sensors, for instance in medical imaging, or on the improvement of telecommunication networks. He has published more than 80 scientific papers in International Journals and has presented at numerous international conferences.

In parallel with his research, Jacques Lewiner has developed many practical applications of his work. He has filed over 170 patent applications, many being extended beyond France to foreign territories. A significant number of these patents have been either licensed or sold.

Jacques Lewiner has participated in the creation of various technology oriented start up companies, for instance Inventel, specializing in Telecommunications, Finsécur which develops and markets fire detection systems, Roowin in the field of chemical synthesis and Cynove in embedded electronics devices, Cytoo which develops and manufactures cell system analysis and Inventel, which was the French leader for multimedia gateways. Most of these companies have experienced a strong (and in some case spectacular) growth. For instance Inventel was bought by Thomson in 2005.

Jacques Lewiner is active in building bridges between research and industry, and in convincing researchers of the importance of filing patents in parallel with their scientific activities and helping in their implementation.

Finally, conscious of the importance of making science accessible to the general public, he founded with Pierre-Gilles de Gennes l'Espace des Sciences de Paris (recently renamed “Espace Pierre-Gilles de Gennes”). Conferences for non specialized audiences are organized as well as short internships for children. It has become one of the pillars of the “la main à la pâte,” a new approach to teaching science to children, initiated in France by Georges Charpak.

He also founded in 1991 with Jacques Lévy, Director of the École des Mines de Paris, and Jacques Lagardère, Director of the École des Ponts et Chaussées, the Groupe des Ecoles d'Ingenieurs de Paris (Paris-GEI), which became ParisTech in 1999. In 2007, ParisTech became a public establishment of scientific cooperation. It now comprises 12 prestigious institutions: Agro ParisTech, Arts et Métiers ParisTech, Chimie ParisTech, École des Ponts ParisTech, Ecole Polytechnique ParisTech, ENSAE ParisTech, ENSTA ParisTech, ESPCI ParisTech, HEC ParisTech, Institut d'Optique, Mines ParisTech, Télécom ParisTech.
