Hank Mahler, father of SMPTE colour bars and developer of triax, dead at 84

October 5, 2021 marked the passing of a true motion picture and television engineering icon, Henry (Hank) Mahler at age 84. Mahler played a key role in developing a number of industry standards and systems, including SMPTE colour bars and the triax cable system. After graduating from Stevens College in the US with a BSEE, Mahler joined the CBS Technology Center in Stamford, Connecticut. One of his first projects at the technology center was destined to become one of the most widely used audio processing technologies: the CBS Laboratories Audimax and CBS VoluMax, which were considered the “gold standard” for audio processing used in the AM/FM and television broadcasting industry.
