Boris Rosing
Boris Rosing Lvovitch (Russian Борис Львович Розинг, scientific transliteration Boris L' vovič Rozing; * 23 Apriljul / 5 May 1869greg in Saint-Petersburg, .. † April 20, 1933 in Arkhangelsk ) was a Russian physicist, engineer and pioneer in the field of television.
Biography
Rosing graduated in 1887, the high school studies with a Gold Medal ( highest award ) and in 1891 to study at the Faculty of the University of Saint -Petersburg Physics and Mathematics with a diploma of the first degree. He stayed first at the university in order to prepare for a professorship and taught at the St. Petersburg Technological Institute, from 1895 to the Konstantinovsky Artillery School. At the same time he continued actively for higher education for women and was a lecturer at the Polytechnic in 1906 opened courses for women who were converted in 1916 into the Petrograd Polytechnic Institute.
Boris Rosing invented the first mechanism for displaying the television picture way, using the system of row-wise transmission and reception device, a cathode ray tube (developed by German inventor Ferdinand Braun) einbaute. He defined de facto the main principle of modern television. In July 1907 his invention was officially registered as a " method of electrical transmission of images across distances ." He got the patent No. 18076 and were honored by the Russian Technical Society.
1908 and 1909, the invention of the new method of image reception was confirmed by additional patents that received Rosing in England and Germany. Rosing 1911 patented an improved television apparatus in Russia, England, Germany and the USA. On May 9, 1911 he succeeded in his laboratory by a self-constructed kinescope of the reception of the simplest geometric figures, what the world's first television transmission meant and ushered in the era of television.
1920 organized Rosing in Yekaterinodar a physical- mathematical society of which he became president. The Company was a member of the Russian Association of Physics and worked actively in spite of civil war turmoil and famine in Russia's south. Rosing published numerous works on the subject of vector analysis, photoelectric relays and transformations of the electric field. In 1922 he took part in the physicists meeting in Nizhny Novgorod and gave a presentation on the behavior of photons as a function of electromagnetic fields. A year later he published in Petrograd his major work called Electric Tele copy ( TV ) - Role and achievements.
Among the students Rosings counted another Russian pioneer of television Vladimir Zvorykin. He emigrated to the United States and invented there on the basis of Rosing's experiments, the Ikonoskop tube that modern kinescope tube and worked on the development of the electron microscope.
1931 Rosing was arrested for alleged " financing counterrevolutionary activities " because he had a friend who was arrested previously borrowed money. For this he was banished for three years in a labor camp OGPU Ulag to Kotlas, a small town in the far north. However, he could be moved thanks to the intercession of the Soviet and foreign scientific public in 1932 to Archangel, where he worked at the Institute of Physics of the Arkhangelsk Forestry Institute. On April 20, 1933 Rosing died at the age of 64 of a cerebral hemorrhage. On November 15, 1957, the Presidium of the Leningrad City Court ruled that the allegations against Rosing were baseless and rehabilitated him posthumously.
