History of electrochemistry
In 1789, Franz Aepinus developed a device with the properties of a "condenser" (now known as a capacitor.) The Aepinus condenser was the first capacitor developed after the Leyden jar, and was used to demonstrate conduction and induction. The device was constructed so that the space between two plates could be adjusted, and the glass dielectric separating the two plates could be removed or replaced with other materials.
Benjamin Franklin Bailey
He became professor of electrical engineering at the University of Michigan in 1913 and was department chairman from 1922 until his retirement in 1944. In the 1920s, he invented the capacitor motor.
