wait....Jimmy Olsen knows the dynamic duo's identities, but not Supes?
Even in the frequently wacky "Weisingerverse" I always thought this was extremely far-fetched.
Batman and Robin tell Jimmy Olsen their secret identities, but otherwise not even their closest friends, including Commissioner Gordon?
Yeah, right.
I think Edmond Hamilton, in the pages of
World's Finest Comics in the mid-1960s came up with this dumb idea.
Much as I greatly admire Hamilton as probably the greatest Superman (and better than average Batman and Legion author) writer of the 1950s and 1960s - he wrote a high proportion of the best Superman stories of this era, in my opinion - I think this is one of his few failings.
I can't recall any post-1970 story where Jimmy displayed this knowledge, so the idea may have been quietly dropped ...
