Romanian professor "True patriarch of Romanian chemistry, with a figure of a prophet" - was characterized Nicolae Teclu, by Nicolae Iorga, his colleague Academy, in one of his admirable portraits. At the beginning of modern chemical science in our country were the figures of three prominent figures: Nicholas Teclu, Petru Poni and Constantin Istrati. Poni remembers how, for nearly four decades, Teclu, living in Vienna, came to the country to take part with great regularity at major academic sessions (he was elected member of the Romanian Academy in 1879). Born in Brasov, Teclu followed education at the Polytechnic School in Vienna and at the Academy of Fine Arts in Munich and Berlin, and later studied at the University of Vienna general and analytical chemistry. After teaching briefly at the Romanian secondary school in Brasov, his value imposed in the capital of the Austrian Empire, where he became (in 1871) professor of technical chemistry at the Academy of Commerce and teaches pigments chemistry at the Academy of Fine Arts. Nicolae Teclu’s work as a chemist and inventor brought early international reputation. He elaborated, for example, new methods for resistance and paper gluing degree determination, built a device for measuring atmospheric electricity, designed a motor flying vehicle (this one had not been achieved, due to lack of funds), had made significant contributions in the study of combustion and flame, had invented a indicator device, measuring the concentration of "fire damp", as is called, life-threatening miners, explosive gas mixture. He had also developed new methods of chemical analysis and various laboratory equipments: for ozone and carbon dioxide preparation, for determination of bodies transparency, for the study the gas flow through the vessels, etc.; most famous and valuable of these was the so-called bulb Teclu (1892). It is actually a gas burner fitted with regulator, widely introduced in European laboratories, higher efficient as all previous devices used. He was also a pioneer of modern forensic science, creating, among other things, methods for reading signs printed or written on charred papers (bills, acts, letters), who allowed spectacular resolution of controversial court cases . This coryphaeus of science was at the same time, a great lover of beauty, nature and arts. He A crossed often mountain shepherds paths, organized training and gymnastics societies (in Brasov and Vienna). For Romanian culture, Teclu remains primarily one of the greatest inventors; asserted on the national and world science orbit, whose creation was stated in manuals, handbooks and encyclopedias worldwide. Laboratory apparatus designed by him, remarkable for their ingenuity, were donated to the University of Bucharest, where are still preserved, as a symbol of his commitment to the Romanian people. |
