Biography

The future scientist was born in June 1850 on the sixth in the "cradle of Catholicism", the small German town of Fulda. Little Karl's father was an official in Hesse, which made it possible to attach the boy to the local gymnasium without any problems. After completing his secondary education, Brown went to Margsburg in 1868, where he entered the Philip University, Germany's first Protestant university. The very next year, Brown received an offer to work in the laboratory from Heinrich Magnus, the young scientist accepted this offer without hesitation and moved to Berlin.

Career

After graduation, the promising physicist had many ideas and even more financial problems. In order to somehow rectify his plight, Karl in 1873 passed the exam for the position of a gymnasium teacher. From the following year, he began work as a mathematics teacher at St. Thomas's School in Leipzig. The workload at the school was relatively low, which allowed the scientist to carry out his main activity - the study of electric current oscillations.

In 1874, he made the first discovery in the field of electricity - he was the first to notice that different metals have different resistance and conductivity of electric current, and he carefully studied this phenomenon.

In 1877, Brown returned to the University of Marburg, where he became professor of theoretical physics. After working there for only three years, he moved again. This time in Strasbourg, where he gets a job at the University of Karlsruhe. Despite frequent travels, Brown has always won the attention and respect of his students. Largely due to a simple and understandable form of presentation of the material even for an amateur. In 1875 he even published his own textbook, Young Mathematician and Natural Scientist. His most famous students were Leonid Mandelstam and Nikolai Papaleksi, who later became pioneers of the Russian school of high-frequency technology.

Karl Brown gained real fame and recognition thanks to his invention - the Brown tube, which became the basis for the creation of picture tubes. The first use of Brown tubes began with the creation of oscilloscopes, but after changes and improvements in the design, picture tubes became the main and integral part of televisions. In addition, the scientist's works were used in the development of intelligent antennas and radars.

Personal life and death

Brown devoted his whole life to science, his wife, Amelie Buehler, supported her husband in everything and bore him two sons. In recent years, he has worked especially hard. In 1915, despite the outbreak of the First World War, Brown reached the United States, where he tried to defend his rights to the Telefunken radio station, but this was not done. In 1917, the United States entered the war and took over the radio station in favor of the US military. Karl Brown died at the age of 67 on April 20, 1918 in the city of New York at the house of his son Konrad, where he spent the last years of his life.
