REFERENCES: Inculet II et al.: The Modern Problems of Electrostatics with Applications in Environment Protection, p. 14: "Romania also brought his contribution to the historical development of the elctrostatics through the studies of Dragomir Hurmuzescu who was the author of the most correct experiment of that time for establishing Maxwell's constant confirming with a high precision degree, that this ratio, equals the value of light velocity. These studies made the object of Hurmuzescu's doctoral thesis 'Sur une nouvelle détermination du rapport entre les unités électrostatiques et électromagnétiques' made under the guidance of Gabriel Lipman a future Nobel Prize Winner. Hurmuzescu's electroscope insulated with 'dielectric' material (insulator avoiding power losses) become the favorite equipment of the gretest experimenters of the time, such as Marie and Pierre Curie, Brcquerel, who made use of it in the measurements of electric charge state."; Banabic D: History of Romanian Technology and Industry, vol. 2, p. 13: "In his doctoral thesis, defended at the Sorbonne, Dragomir Hurmuzescu builds upon an idea first advanced by Maxwell to determine, based on an original method, the most accurate value of the v ratio (ratio of the electromagnetic and electrostatic units of charge) from which the speed of light is obtained. Rosa and Darsey from the American Bureau of Standards mention that the result determined by D H is the most accurate, 300,000 per second (1895) as compared to the one calculated by Maxwell, which was 280,000 km per second (1868)."; Teodoresc HN: The importance of an initiator - the case of the school of sensors in Iasi, Romania, Memoirs of the Scientific Sections of the Romanian Academy, 2018:?Even after one century, Hurmuzescu's contributions are cited and his work highlighted in reviews such as that of Roberto de Andrade Martins, The rise of magnetochemistry from Ritter to Hurmuzescu (in "Foundations of Chemistry", July 2012). Hurmuzescu developed studies on various issues in magnetism, including topics such as: the electromotrice force of magnetisation; the mechanical, physical, and chemical changes induced by magnetization, and the connections between the electrostatic and electromagnetic units.".
