At one point in his life, Howard was shocked by a 6000 volt generator.
When his nephew John T. Johnson was about 15, Howard gave him some transformers to experiment with. Unknowingly, John connected one backward to a safe voltage, making it step the voltage up to about 300 volts. John touched the wires and got "stuck" on the wire because of the high voltage. He was dying, when his mom Alice Parker Johnson saw what was happening and "knocked him off the wire. He has a scar on his right thumb where the thumb was charred by the voltage.
