Walter Bruch

[2] In addition to his research activities Walter Bruch was an honorary lecturer at Technische Hochschule Hannover.

At his father's request he attended a business school, but then trained as a machinist apprenticeship in a shoe factory.

The Summer Olympic Games of 1936 in Berlin became a milestone for audiovisual technology and Bruch was able to field test the first Iconoscope camera, developed by Emil Mechau based on a tube by Walter Heimann [de].

His work led him and co-workers like Gerhard Mahler [de] 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.
