Seems there was! I'm just wondering, since thermionic valves and
semiconductors were yet to be invented, just what the hell they were
generating curves of? Anyone care to hazard a guess?
Must have been some interest in non-linear resistances. There were
electrolytic rectifiers around about that timeframe too, I recall a 1908
book describing them for battery charging.
