Jan Rudolph Deiman

Jan Rudolph Deiman or Johann Rudolf Deimann (29 August 1743 – 15 January 1808) was a German-Dutch physician and chemist who was among the first to examine electrolysis of water, and examine the application of electricity for medical uses along with Adriaan Paets van Troostwijk.

His mother died when he was a year old, and after the death of his father around 1758 he lived with his older brothers and apprenticed as an apothecary in Leer before studying medicine and philosophy in Halle with Adolph Böhmer.

In 1770 he graduated after writing a Dissertatio inauguralis de indicatione vitali generetium and soon moved to practice medicine in Amsterdam.

He studied philosophy and participated in discussions of learned societies, becoming a member of the Hollandse Maatschappij der Wetenschappen te Haarlem in 1783, and began to collaborate on experiments along with Adrian Paets van Troostwijk.
