...that one person who claimed to be the inventor of the television is Russian emigre Vladimir Zworykin?

Before his death in 1982 at the age of 92, Zworykin said of his invention: "The technique is wonderful. It is beyond my expectations. But the programs! I would never let my children even come close to this thing."
