Extractions: Ferdinand Braun Historia-Photo in full KARL FERDINAND BRAUN (b. June 6, 1850, Fulda, Hesse-Kassel [now Germany]d. April 20, 1918, Brooklyn N.Y., U.S.), German physicist who shared the Nobel Prize for Physics in 1909 with Guglielmo Marconi for the development of wireless telegraphy. Braun was recognized by the Nobel committee for his improvement of Marconi's transmitting system. In early wireless transmission, the antenna was directly in the power circuit and broadcasting was limited to a range of about 15 kilometres. Braun solved this problem by producing a sparkless antenna circuit (patented in 1899) that linked transmitter power to the antenna circuit inductively. This invention greatly increased the broadcasting range of a transmitter and has been applied to radar, radio, and television. Braun's discovery of crystalline materials that act as rectifiers, allowing current to flow in one direction only, led to the development of crystal radio receivers. Braun is also known as the developer of the cathode-ray oscilloscope . He demonstrated the first oscilloscope (Braun tube) in 1897, after work on high-frequency alternating currents. Cathode-ray tubes had previously been characterized by uncontrolled rays; Braun succeeded in producing a narrow stream of electrons, guided by means of alternating voltage, that could trace patterns on a fluorescent screen. This invention, the forerunner of the television tube and radarscope, also became an important laboratory research instrument.

Extractions: (A very good biography of Braun, reprinted with permission) Ferdinand Braun shared the 1909 Nobel prize with Marconi "in recognition of their contributions to the development of wireless telegraphy". While Marconi was tenacious and ingenious in the development of wireless telegraphy, it was Braun who hammered out the theory on the anvil of science. Some of the discoveries made by Braun and utilized by Marconi are: Combining a Leyden Jar with an enlarged coil. Thus lowering the frequency of oscillation to a more manageable range. While this is a very simplistic treatment of a complex subject I feel that F. Braun has received very little recognition (especially outside of Europe) of his contributions to wireless telegraphy. (As compared to Marconi) For more information I highly recommend Friedrich Kurylo's Biography of Ferdinand Braun. The forward can be viewed

Extractions: Dr. Karl Ferdinand Braun - 1850 - 1918 The German physicist Karl Ferdinand Braun, b. June 6, 1850, d. Apr. 20, 1918, shared the 1909 Nobel Prize for physics with Guglielmo Marconi for his work in developing the radio. Braun, who spent his career as a professor of physics at German universities, increased the range of Marconi's transmitter, invented the crystal rectifier ( a device that allows current to flow in only one direction, and improves radio transmission ), and later invented the oscilloscope, a cathode-ray-tube laboratory device that was the forerunner of today's television and radar tubes. Source: The New Grolier Multimedia Encyclopedia Although German physicist Braun's main contributions were in pure science, he is best known for developing the first cathode-ray ( the 'Braun tube' ) oscilloscope in 1897. This device produced line graphs of rapidly varying electrical signals and was the ancestor of today's television screen.

Extractions: Nach Schulbesuch und Abitur in seiner Heimatstadt Fulda studierte Ferdinand Braun Mathematik und Physik in Marburg und Berlin. Am 23. November 1874 gelang ihm als Lehrer an der Thomas-Schule in Leipzig der erste große wissenschaftliche Erfolg seines Lebens. Er entdeckte den Gleichrichtereffekt der Halbleiter , auf dem die heutige Elektronik beruht. Mit 26 Jahren wurde Braun zum außerordentlichen Professor für theoretische Physik nach Marburg berufen. Mit 35 Jahren ging Braun nach Tübingen. Hier entwickelte er unter anderem das Braunsche Elektrometer (1891). Im Jahre 1895 ging Braun nach Straßburg und wurde dort 1905 Rektor der Universität. 1896 entstand seine berühmteste Erfindung, die Braunsche Röhre , eine Kathodenstrahlröhre zur Untersuchung der Form elektrischer Schwingungen, aus der sich die heutige Fernsehbildröhre entwickelte. Eine weitere bedeutende Erfindung glückte Braun 1898 auf dem Gebiet der drahtlosen Nachrichtentechnik. Er konstruierte den Braunschen gekoppelten Sender , eine noch heute in allen Sendern und Empfängern gebräuchliche Ankopplung eines geschlossenen Schwingkreises an die Antenne.

Karl Ferdinand Braun was born in Fulda, Germany, on June 6, 1850, the son of Konrad and Franziska (Gohring) Braun. Upon graduation from his local gymnasium, he entered the University of Marburg, later completing his Ph.D. at the University of Berlin in 1872 with a dissertation on the vibrations of elastic rods and strings. Braun next took a lectureship at the St. Thomas Gymnasium in Leipzig, a post he also held for two years. Then, from 1876 to 1880 he was extraordinary professor at the University of Marburg, his
