Nikola Tesla’s Remarkable Experiments With Wireless Lamps and Vacuum Tubes Shown Before the Franklin Institute and the National Electric Light Association in 1893
“These were the most striking results I showed in the transmission of energy… You see how far I have gone into the mastery of electrical vibrations in 1893. I stand here [Fig. 190] in the hall, holding a lamp in my hand, and the energy transmitted lights it. Here again [Fig. 191] I hold a phosphorescent bulb in my hand, and here [Fig. 192] a vacuum tube.
“These experiments, I remember, were made in St. Louis. There was a hall with 6,000 or 7,000 people. When I explained how I had shown a phosphorescent bulb to Lord Kelvin in England, and told them that the bulb was going to spring into light, and the current was turned on and it did burst into light, there was a stampede in the to upper galleries and they all rushed out. They thought it was some part of the devil’s work, and ran out. That was the way my experiments were received.”
