Overview
In Nov 1703, with the passing of Robert Hooke (1635-1703), Newton returned to the Royal Society, and appointed Hauksbee as the new Royal Society curator of experiments.

In 1705, Hauksbee, inspired by Jean Picard (Ѻ), who discovered that if he shook a mercury-containing barometer it would produce a glow (Ѻ), placed mercury inside of a Guericke generator, which he built, shown below, which he then evacuated, with a vacuum pump, to make a mild vacuum inside, then rubbed the glass ball to build up a charge, and observed that a glow was visible when he placed his hand on the outside of the globe.
