Dénes Mihály

Dénes ( born 7 July 1894 in Gödöllő (Hungary ); † August 29, 1953 in Berlin) by Mihály was a Hungarian physicist and engineer. He was the developer of a mechanical television system.

Dénes Mihály already dealt to transmit the images of thought electrically over long distances as a student in Budapest. According to his own statements, he 's with his Telehor have succeeded for the first time on July 7, 1919 said apparatus, as he claims to have transferred silhouettes of the moving scissors and forceps three miles through a wire. His apparatus is said to have worked with a Nipkow disk, ie with mechanical scanning.

Laboratory studies show Mihalys allegations of successful TV trials in 1919, however.

In Berlin

Beginning of 1923, Mihály in Berlin- Wilmersdorf the Telehor AG, which operated a television technical laboratory; he published in the same year the first book, which dealt exclusively with the television industry: The electric television and the Telehor. From February 1925, the company also collaborated with the imperial post; so get three years later the first image transfers from the Telehor lab to telegraph Technical Office of the Reich. At the 5th radio show then you could show the public a television picture: The Telehor continued to work with mechanical scanning, he was only 4 x 4 cm, contemplative with a magnifying glass to frame. It consisted of 30 lines and a total of 900 points. 10 image changes per second did not allow for fluid movement. Mihály offered the device as Telehor people television receiver; but it was hardly sold due to the low image quality, especially as no sound transmission was provided. On the night of 8 March 9, 1929 converted by Telehor - image scanner image was broadcast on medium wave, so that it could receive the television technical laboratories in the area of the Reich Post Office Central. Here, too, the limits of a mechanical television became noticeable.

Mihaly found in the cemetery Wilmersdorf his final resting place.
