The Man Who Invented Vaping: A Homage to Hon Lik. We need to start off by acknowledging another manâHerbert A. Gilbert from Beaver Falls, Pennsylvania. In 1963, heavy smoker Gilbert came up with the idea of a battery-powered device with a heating element that could produce vapourâa rudimentary e-cigarette. But the idea never came to fruition. Hon Lik, on the other hand, not only devised a working e-cigarette 40 years later in 2003, he patented the idea and brought it to market in China. He and other companies started exporting to the USA and Europe in 2009, and the rest is history.
