Electricity has been a subject of scientific interest since at least the 17th century. A friction machine was constructed at about 1663 by Otto won Guericke, using a rotating sculpture globe rubbed by hand .lsaac Newton suggested the use of a glass globe instead of a sulphur one. In the latter part of the 18 century, Benjamin Franklin, Ewald jurgen, George von Kleist, and Pieter van Musschenbroek (the last two the inventors of the Leyden jar) made several important discoveries concerning electrostatic machines.
The first suggestion of an influence machine appears to have grown out of the invention of Alessandro Volta's electrophorus .
"Doublers" were the first rotating influence machines .Abraham Bennet, the inventor of the gold leaf electroscope, described a "doubler" or "machine for multiplying electric charges".
