The first electrostatic generators are called friction machines because of the friction in the generation process. A primitive form of frictional machine was invented around 1663 by Otto von Guericke, using a sulphur globe that could be rotated and rubbed by hand.
Otto von Guericke (UK: / ... His electrostatic generator was created using a sulphur globe attached to an iron rod. By rubbing the sphere with a dry hand, von ...
Around 1650, Otto von Guericke built a crude electrostatic generator: a sulphur ball that rotated on a shaft. When Guericke held his hand against the ball and turned the shaft quickly, a static electric charge built up. This experiment inspired the development of several forms of "friction machines", which greatly helped in the study of ...
In 1663, Otto von Guericke generated static electricity with a device that used a sphere of sulfur. [1] Francis Hauksbee developed a more advanced electrostatic generator around 1704 using a glass bulb that had a vacuum.
German scientist Otto von Guericke invented a device that creates static electricity. This is the first ever electric generator. 1705: English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand 1720: English scientist Stephen Gray made the distinction between insulators and conductors. 1745

German physicist Otto von Guericke beside his electrical generator while conducting experiment. In 1663, German physicist Otto von Guericke created the first electrostatic generator, which produced static electricity by applying friction. The generator was made of a large sulfur ball inside a glass globe
By 1705, Hauksbee had discovered that if he placed a small amount of mercury in the glass of his modified version of Otto von Guericke's generator, evacuated the air from it to create a mild vacuum and rubbed the ball in order to build up a charge, a glow was visible if he placed his hand on the outside of the ball. This remarkable discovery ...
