  Braun
Karl Ferdinand Braun was born on June 6, 1850 in the German city of Fulda.
Braun's first investigations were concerned with oscillations of strings and elastic rods, especially with regard to the influence of the amplitude and environment of rods on their oscillations.
Braun then reduced the number of antenna wires and poles to three and was able to excite the wires from a common transmitter by arranging the poles in an equilateral triangular pattern.

In 1897 he built the first cathode-ray tube oscilloscope, the CRT is still called the "Braun tube" at the University of Karlsruhe, Germany.

 VIAS Encyclopedia: Karl Ferdinand Braun
Karl Ferdinand Braun was born on June 6, 1850, in Fulda as a son of a court official.
The principle of his transmitter, on which the modern communications technology, including radio and television, drew, was based on the separation into a non-radiating primary system (consisting of resonant circuit and spark gap) and a secondary system for radiation over an antenna.
In 1913, Braun conducted the first absolute field strength measurement with a coil aerial of the transmitter on Paris Eiffel Tower.

 Karl Ferdinand Braun Summary
Karl Ferdinand Braun was born in Fulda, Germany, on June 6, 1850, the son of Konrad and Franziska (Gohring) Braun.
Braun found his answer in the creation of a sparkless antenna circuit--power from the transmitter was magnetically coupled through the transformer effect to an antenna circuit rather than directly linking it to the power circuit.
Braun was educated at the University of Marburg and received a Ph.D from the University of Berlin in 1872.

Karl Ferdinand Braun, German physicist and Nobel Prize winner was born on 6 June 1850 in the German town of Fulda.
As an experimenter and physicist, Braun is most famous for his invention of the cathode ray oscilloscope (the forerunner of the television tube and radar tubes) and for his contributions to wireless telegraphy (that is, radio).
Braun discovered that a stream of electrons emanating from a negatively charged electrode inside a vacuum tube—a cathode ray—could be focused to a point at the end of the tube.

Braun, who was born in 1850 in Fulda, Germany, was awarded the Nobel Prize in physics in 1909.Vladimir Zworykin and Boris Rosing built on Braun’s work when they were trying to transmit pictures by wire in a physics laboratory.
Braun died in 1918 in New York, but is remembered by the Karl Ferdinand Braun Prize.

 OTB - "Forgotten" Pioneers of Wireless, Part 5 - Karl Ferdinand Braun
This information was all Braun needed in 1897 to build what he called his "cathode ray indicator tube." (The term "cathode ray tube" without the word "indicator" included was often used in those days to refer to any evacuated tube used for studying the effects of cathode rays.) [2, 6].
Braun knew that having an improved receiver also was critically important to achieving a truly commercially successful system of wireless telegraphy.
Braun's crystal detector, however, was "rediscovered" and improved in a few years by others for use as an inexpensive and reasonably reliable detector for radiotelephony [2].

 June 1997 Newsletter - Page 3
Karl Ferdinand Braun (1850-1918) is credited with inventing the modern CRT in 1897 while he was a professor of physics at the University of Strasbourg.
Braun’s tube contained all of the basic functions of today’s CRT, and, unlike most of its predecessors—notably those built by Sir William Crookes and Wilhelm Roentgen—Braun’s tube had a purpose beyond that of a laboratory research device.
Braun’s invention, and the CRT technology it spawned, was the subject of an exhibit entitled From the Braun Tube to the Information Age, 1897-1997 sponsored by the Society for Information Display, May 13-15 in Boston, Massachusetts.
