Walter Bruch (2 March 1908 – 5 May 1990) was a German
Biography
He was born in Neustadt an der Weinstraße in the German Empire. At his father's request he attended a business school, but then trained as a machinist apprenticeship in a shoe factory. From 1928 he attended the university of applied science Hochschule Mittweida in Saxony. After that, he was a guest student at the Technical University of Berlin, where he met Manfred von Ardenne and the Hungarian inventor Dénes von Mihály.
From the early 1930s Bruch was involved in the development of television technology: in 1933 he presented a "people's television receiver" with a self-built
In 1950, Telefunken commissioned him to develop the first post-war television receivers. Some time later, he returned to physics research and later colour television. He studied and thoroughly tested the American NTSC system and what would later become the French SECAM system. His work led him and co-workers like Gerhard Mahler and Dr. Kruse to devise a new colour television system that automatically corrected for the differential phase distortion that can occur along the transmission channel.
On 3 January 1963, he gave the first public presentation of the Phase Alternation Line System to a group of experts from the European Broadcasting Union in Hannover. This is considered to be the date of birth of the PAL-Telefunken system, which was later adopted by more than thirty countries (at present, more than one hundred). When interviewed by German talk show host Hans Rosenthal on why he had named it the "PAL system", Bruch replied that certainly no German would want to have a "Bruch-System" had his family name been used as the eponym; Bruch in German is synonymous with "broken".
