Adriaan Paets van Troostwijk (1752-1837) and Jan <Jahan> Rudolph Deiman<n> (1743-1808) where Dutch researchers who observed water decomposition under electric discharge. We can assume that the observed process was plasma-induced, probably with some contribution of the real electrolysis. This follows from information about Cuthbertson generator used in these experiments in combination with Leyden jars, and also from ….
