Summary/Abstract: Physicist Dragomir Hurmuzescu obtained his Bachelor’s and Doctoral degrees at the University of Paris, under the guidance of famous Gabriel Lippmann, winner of the Nobel Prize in Physics in 1908. The Romanian physicist is the one who established, in 1894, the electromotive voltage formula of a galvanic cell with metal poles. Together with the Frenchman Louis Benoist, Hurmuzescu discovered that X–rays had the property of discharging electrified bodies. The Romanian physicist invented dielectrine, an electrical insulating material based on sulfur and paraffin, used in the invention of the “Hurmuzescu electroscope”, with the help of which Pierre and Marie Curie discovered radium. Hurmuzescu is also considered the “father of Romanian broadcasting”, under his guidance being built, in Bucharest, in 1926, the first broadcasting station in Romania. Professor Hurmuzescu was also active in other fields such as ensuring radio links of Romania with other countries, through radio waves, an objective achieved in 1914 by Emil Giurgea, his collaborator, expanding the field of broadcasting, accelerating the establishment of the first national broadcasting station, supporting and popularizing the amateur radio movement. Professor Dragomir Hurmuzescu took care of the training and guidance of some outstanding specialists, who activated under his guidance.
