John Cuthbertson (instrument maker)

John was the second son of the inn keeper and yeoman Jonathan Cuthbertson and his second wife, Mary Fisher.

It had disks with a diameter of 1.65 m (5 ft 5 in) and was connected to a battery of Leyden jars to store the charge produced.

The machine was based on a smaller model produced by Jonathan Cuthbertson shortly before, but with some significant changes, such as glass poles instead of wooden ones.

[3] Sometime between 1793 and 1796 he returned to England, living in Poland Street in London (contrary to his brother Jonathan who remained in Rotterdam), probably due to the political unrest in the Dutch Republic.

Almost all conditions, including gout, fever, hydrocephalus, blindness, deafness and genitor-urinary infections were supposed to be treatable by the application of electricity.
