Shall we say a fond farewell to Russell Johnson, 'The Professor' from TV's "Gilligan's Island"?

I remember him better as a frequent guest actor on TV, dince I came to loath ”Gilligan”. From the ”Twilight Zone” to ”Newhart” he seemed a better actor that what he was ever given credit for.

RIP, ‘The Professor’, Russell Johnson. Ginger and MaryAnn are the only members yet to join the rest of the cast.
