One man who claimed to in
One man who claimed to invent this object derived inspiration for it by looking at a potato field in Idaho. That man's progress was delayed when his laboratory burned down twice. Another man (*)  who claimed to have invented this device said of it: "I never let my children near the thing". A doll's head was used in the first demonstration of this device, and Johann Hittorf used a Crookes Tube to discover a type of radiation key to the functioning of this device. A process called "degaussing" had to be used on early versions of this device. For ten points, name this device that originally used a Cathode Ray Tube to send visual signals.
