Sheaths were first described by American physicist Irving Langmuir. In 1923 he wrote: "Electrons are repelled from the negative electrode while positive ions are drawn towards it. Around each negative electrode there is thus a sheath of definite thickness containing only positive ions and neutral atoms.
