From an article in The Electrical Experimenter (1920), where note is made that -
Bre’r Rabbit taking a trifling 500,000 volts at 20 kilowatts, and liking it well, thank you! He held still for 20 seconds, only blinking once in awhile. He was not chained nor held down otherwise…He is still alive, so Sis needn’t worry that we killed him.”SciFi enthusiasts will know (or be pleased to learn) that the editor of The Electrical Experimenter was none other than Hugo Gernsback.
