Braun contributed significantly to the development of radio and television technology: he shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy". ==Biography== Braun was born in Fulda, Germany, and educated at the University of Marburg and received a PhD from the University of Berlin in 1872.
In 1874, he discovered that a point-contact semiconductor rectifies alternating current.
He became director of the Physical Institute and professor of physics at the University of Strassburg in 1895. In 1897, he built the first cathode-ray tube (CRT) and cathode ray tube oscilloscope.

In 1897, Braun joined the line of wireless pioneers.
Around 1898, he invented a crystal detector .
Braun's full attention in 1898, and for many years after that he applied himself almost exclusively to the task of solving its problems.
In 1899, he would apply for the patent Wireless electro transmission of signals over surfaces.
Also in 1899, he is said to have applied for a patent on Electro telegraphy by means of condensers and induction coils . Pioneers working on wireless devices eventually came to a limit of distance they could cover.
In spring 1899, Braun, accompanied by his colleagues Cantor and Zenneck, went to Cuxhaven to continue their experiments at the North Sea.
On 24 September 1900 radio telegraphy signals were exchanged regularly with the island of Heligoland over a distance of 62 km.

The resultant stronger and less bandwidth consuming signals bridged a much longer distance. Braun invented the phased array antenna in 1905.

In 1909, Braun shared the Nobel Prize for physics with Marconi for "contributions to the development of wireless telegraphy." The prize awarded to Braun in 1909 depicts this design.
