Born November 20, 1911, Cernauti (Austro-Hungary). Studies in Chemistry (1931) and in Physics (1933) in the University of Cernauti (Romania). After finihing his high studies Radu Grigorovici was appointed as assistant in the Department of Experimental Physics of the University (Department leader: Professor Eugen Badarau). In 1937 he moved to the University of Bucharest. There he finished his Ph. D. Thesis (1938) entitled: Disruptive potential in Hg vapour. Scientific Advisor: Prof. E. Badarau. In 1960 he occupied the position of tenure in the Faculty of Mathematics and Physics of the University of Bucharest and teached optics for the students of the Physical Section.Radu Grigorovici was appointed in 1960 as Chief of Department in the Institute of Physics – Bucharest, and, three years later, in 1963, was appointed Vice-Director of the Institute. Professor Grigorovici retired in 1973 but continued to work in the institute with his pupils for more than 20 years. After the revolution of December 1989, he was elected as Vice-President of the Academy of Sciences of Romania.Professor Grigorovici is now continuously interested in the research in the physics of condensed matter. Professor Grigorovici published a high number of papers in the field of: electrical discharges in gases, high frquency torch, flame spectral analysis, trichromatic colorimetry, thin metallic films and, last but not least, amorphous semiconductors.The main achievement of Prof. Grigorovici was in the field of amorphous semiconductors. He and his collaborators developed the first structural model for an amorphous semiconductor (germanium) in 1969 and put the basis of the amorphous semiconductor field in the world research. His contribution in this field was mentioned in the Nobel Conference by Sir Nevil Mott, the recipient of Nobel Prize in Physics for 1977.
