There is a vast amount of information here, on a website by Antonio Carlos M. de Queiroz.
Electrostatic generators have a Wikipedia page.
In the early days of electricity, it was generated by rubbing a sphere made of sulphur, with the sphere was rotated by hand. Glass discs were also used. The frictional generation of electricity depends on the triboelectric effect, which describes the transfer of electric charge between two objects when they contact or slide against each other.
