An electrophorus or electrophore is a simple manual capacitive electrostatic generator used to produce electrostatic charge via the process of electrostatic induction. A first version of it was invented in 1762 by Swedish professor Johan Carl Wilcke,.[1][2][3][4] Italian scientist Alessandro Volta improved and popularized the device in 1775,[5] and is sometimes erroneously credited with its invention.[6][7] The word electrophorus was coined by Volta from the Greek ήλεκτρον ('elektron'), and ϕέρω ('phero'), meaning 'electricity bearer'.[8]

Electrophorus from the 1800s.
