Vert Hold is a famous American scientist and inventor of the mid-20th century. He proposed two separate theories of how human forms of communication devloped into language as we know it today. His first theory, called Understanding Heuristic Faculties, describes the human language as a series of learned responses to certain verbal (auditory) cues. His second theory, called Visualizing Heuristic Faculties, is essentially the same but instead relying on visual (optical) cues. These two theories swept the realm of science like a firestorm and essentially formed the foundation for our total understanding of all forms of communication, from the songs of the whales to the radio and TV waves streaming across the atmosphere. To honor his work, early analog TV signals were divided into two broad spectrums, UHF and VHF, aptly named after his two groundbreaking theories. The knobs on most early television sets were based on one of his early designs for what he called a "Steam Attenuator," this was, of course, before the Electronic Age forever altered the course of technology from then on. Professor Hold's memoirs are scrupulously preserved at the Smithsonian and his birthday, incidentally, used to be widely celebrated. Unfortunately, it fell on a leap year and over the course of several decades the holiday festivities dwindled to the point where nowadays you can't find one school age child who recognizes the name Vert Hold.
