Tecuci Gheorghe Tecuci Romanian Academy George Mason University Mihai Dr˘ag˘anescu With outstanding contributions in Electronics, Informatics, and Philosophy, and as Professor, Re- searcher, and Manager, Acad. Mihai Drag˘ anescu˘ is the most important encyclopedic personality of contemporary Romania. Educated in the nascent Romanian school of electronics, Acad. Mihai Drag˘ anescu˘ creates a world- class school of electronic devices and microelectronics. Envisioning the evolution of the modern society, becomes initiator and promoter of the informatics revolution in Romania, conceptually defining it and coordinating its development. Generalizing the concept of information, creates an original philosophy that leads to the development of a new type of science, called structural-phenomenological, with major implications for the understanding of the world and its future. First president of the Romanian Academy renaissance, he leads both its return to its role and traditional sources, and its renewal and adaptation to the evolution of the civilization. Promoter of the scientific and humanistic culture, brings back the deserved recognition to major personalities of the Romanian spirituality. Mentor and life model, he lightens and encourages many young generations with an extraordinary generosity. Any of these achievements would be enough to place Acad. Mihai Drag˘ anescu˘ among the greatest Romanian personalities. Their combination, impressive through their diversity and unity, creates the image of a personality of a rare complexity and creativity. 1 Founding Father of the Romanian School of Electronic Devises and Mi- croelectronics Acad. Mihai Drag˘ anescu˘ was educated as an electronics engineer, and climbed through all the pro- fessional levels, from assistant professor to academician. Despite the unsupportive research environment of an isolated Romania, he succeeded in obtaining truly outstanding results. At the beginning of his scientific career, as a young assistant professor, Mihai Drag˘ anescu˘ is among the very few Romanian electronics engineers with world-class research results, author of the first Romanian PhD in the area of Copyright °c 2006-2009 by CCC Publications A Life Dedicated to the Science, Philosophy and Romanian Society 317 electronic devises, entitled “The Capacities of Electronic Tubes and Their Dependence of the Function- ing Conditions”.
