The Elongated Man - Technically Batman told him in Detective Comics #331, but Bats only did that knowing that EM would lose his memory of everything he learned at that time.

Hawkman & Hawkgirl - Brave & The Bold #70 - This story showed that Batman did know Hawkman & Hawkgirl's secret identities & I'd assume they knew his because of the Absorbascon when they came to Earth (they'd just have to concentrate about it to bring up the info.)

Ka-Thar - World's Finest Comics #81 - a historian from 5956 knows who they are.

Lance Bruner - Brave & The Bold #83 (the "Punish not my Evil Son" story already mentioned) Lance discovered the Batcave & figured it out.

Mr. Jupiter - While not specifically stated, he had to know by Teen Titans #35. In that story the Titans & Mr. Jupiter are in Italy. Robin appears out of costume & Mr. Jupiter calls him Robin. Now in Teen Titans #25 when Mr. Jupiter first appeared Robin recognizes Mr. Jupiter as a friend of Bruce Wayne & would doubtless know who Dick is.

Doubtful Cases & Near Misses

Aunt Harriet - Detective Comics #351 - she found the elevator to the Batcave & believed Bruce & Dick were B&R, but by the end of the story they convinced her she was mistaken.

Balthazar T. Balthazar aka The Collector - Brave & The Bold #70 - his computer figured it out, but later Bats & Hawkman confused the heck out of him.

Commissioner Gordon - Batman Family #11 - while not explicitly stated the story has Gordon putting the clues together & ends implying that he knows the truth.

Governer Andrew Warner - Batman #165 - after being mutated into a future man he gave clues to a way that he could be defeated, clues that only his friend Bruce Wayne would have known so Bats suspected he had learned the secret telepathically, but didn't know for sure. Warner was sent off in a rocket in suspended animation.

Elwood Pearson & Mr. Incognito - Batman #173 - Pearson had a special camera & mirror that could show what someone looked like under a mask. Both saw Bruce & Dick's faces, but didn't recognize them. B&R hoped they didn't have time to commit their faces to memory.

Come to think of it, I forgot to mention Slade and Addie's kid who eventually became a Titan in good standing, Jericho, didn't I? [i]Oops![/i]

(Although looking back on it, I have to conclude that if Pre-COIE Mxy didn't know who Superman was, it could only mean he didn't really want to know!)

Bernard the Poet -- about that gender-reversed world which you want to see again . . . did you see how Jeph Loeb gave us glimpses of something very similar in the last story arc he did for the "Superman/Batman" title? (I imagine he too has read that old Pre-COIE story, because his version also had Mxy involved in all the weirdness happening in that story arc.)

At that point in time, there's not much evidence that Denny had his later hang-ups about people knowing the identity. After all, O'Neil created Talia and Ra's as recurring characters who specifically knew The Secret, had the Shadow know it, and probably one or two more examples I'm forgetting without looking back up at the list.

DC should definitely bring it back. It deserves its own series.

This story was also scripted by Bob Haney, who I think we can assume didn't share Denny O'Neil's hang-ups about people knowing Batman's secret.

This may not be the place to write this, but whilst going through my old Brave and the Bold issues, I couldn't help but notice thirteenth entry for your 12 Tricks for Keeping a Superhero Young. In B & B # 84, The Angel, the Rock and the Cowl, Batman teams up with Sgt Rock. The story is set in the present (1969) with flashbacks to June, 1944, but Batman remains ageless throughout while Rock and the evil von Stauffen are visibly older in the present-day section of the story.

Now I can see that Haney was trying to create a fable, but when I was a kid, it irritated the hell out of me.

You also need to add Cain from the House of Mystery, who is shown to know it in Brave and the Bold no. 93.

On your Doubtful Cases list, you might want to add Sgt Rock and Man Bat. Rock parachuted into occupied France with Bruce Wayne, but before you know it, Batman is helping Easy Co. and Bruce isn't anywhere to be seen (Brave and the Bold no. 84). Man Bat finds the Batcave in Detective Comics no. 402.

The Brave and the Bold were all written by Bob Haney, the Man Bat stories were written by Frank Robbins. I hope that's helpful.

I realize that by the time Crisis came around, too many people knew his identity, and they had to trim the number of people knowing...but did they really have to make the Titans characters such morons just to do it? Really? ALL OF THEM where that clueless? I mean, I know Dick was the brains of the team, but still! lol

Deadman learned The Secret in his very first Batman team-up, BB #79.

Lothor -- Frankly, I have no idea whether the Pre-COIE Mxyzptlk ever showed signs of knowing who Batman really was. Heck, offhand I'm not too clear on whether he ever definitely knew who Superman really was! (He may have -- I just wouldn't know! I've read a few of his Pre-COIE stories, but not in ages, and I don't have a photographic memory for whatever I read!)

About Clark's parents -- well, on the one hand, I'm pretty sure Bruce didn't become Batman until after Clark's parents died while Clark was in college. On the other hand, now that you've stirred my memory, I know I have read at least a few stories from the Pre-COIE era that worked on the theory that juvenile Clark and juvenile Bruce were pretty well-acquainted and sometimes worked on cases together (in sharp contradiction to the story I cited in my List, wherein they bumped into each other for the very first time as grown men on a cruise ship) . . . and I even seem to recall that Clark had some device that sometimes let him see into the future so that he, as Superboy, knew that someday Bruce would be Batman . . . so I guess he could have mentioned the "secret identity of Batman" to his parents before there even was a Batman!

On the other hand . . . in "World's Finest #300" Batman ends up traveling through time and manages to save Pa and Ma Kent from a gunman. Superboy pops up just after Bats has disappeared, and as I recall, Ma and Pa just say something like this about their rescuer: "It was a man -- dressed all in black -- he seemed to recognize us and then ran away." That implies a certain failure to recognize "Batman," although admittedly it was only a quick glimpse of him, and there's nothing that would have prevented Clark from telling them all about the future Batman a year later . . .

I guess what it boils down to is that if anyone can show me a story in which Ma and Pa definitely knew, "in continuity," all about Bruce Wayne's future plans before he actually started wearing a Batman costume, then I'll add them to the List -- but at this moment, I don't know of any solid reason to do so!

MarkAndrew -- on the other hand, I can honestly say I'd never even heard of Bruce Wayne's "adopted and deceased ward" before! I'll look into it, as best I can -- probably via online databases, since I don't feel too tempted to spend an arm and a leg to buy a copy of such an old issue of "Brave and the Bold."

He fought in World War II. Then he spent a long time as a dramatic actor in England. Then, as his father, a former butler at Wayne Manor, was dying, Daddy Pennyworth extorted a promise from Alfred to continue the proud family tradition of each generation of Pennyworths having at least one member in domestic service. Very reluctantly, Alfred promised to keep the tradition alive. Deciding to pick up where his father had left off, he sailed across the Atlantic to Gotham and knocked on the door of Wayne Manor, totally unexpected, and informed Bruce and Dick that he was their new butler. Bruce tried to politely explain that Alfred must have the wrong address or something, because Bruce hadn't been advertising for a new butler and didn't really need one. Alfred firmly "corrected" him on that point -- something like "My father served your father, and now I shall serve you. That's the way of the world!" and headed off to find himself a vacant room to sleep in. They couldn't get rid of him . . . or didn't have the heart to use brute force to throw him out, or something . . . but the way it's written, it's clear that the writer (Len Wein) was working on the belief that Bruce never even laid eyes on Alfred Pennyworth until right then and there, well after he had already created the role of Batman; there was no sense of recognition; nothing like Alfred saying, "Young Master Bruce! You've grown considerably since I last saw you!"; nothing even remotely similar.

We then skip ahead to some weeks later. Alfred awoke in the middle of the night to hear someone yelling his name, and found the noise was coming from behind that old grandfather clock downstairs. When he moved the clock aside, he found Bruce and Dick -- still dressed as Batman and Robin -- with Batman suffering from a gunshot wound and Dick more or less dragging him up the stairs. Alfred had apparently learned emergency battlefield medicine during his time in uniform, so he was able to help. (Although looking back at my own list, you'd think they'd have called for Doctor Dundee. I don't remember Dundee ever being mentioned in that miniseries, however.)

As far as I know -- and I think I've read something very close to every issue of "Batman" and "Detective Comics" story ever published by DC throughout the decade of the 1980s -- no "in continuity" story ever had Alfred as a butler who'd been around at the Manor ever since Bruce was just a wee slip of a lad until after the transition to Post-COIE continuity. I do seem to recall the Frank Miller's "Dark Knight Returns" had Alfred reminiscing at least once about what Bruce was like as a small boy, but that wasn't even remotely "in continuity" for the regular Batman titles. Then Miller had Bruce in "Year One" thinking something to the effect that his father had left him with the services of a butler trained in battlefield medicine, and that story arc seems to have first established "in continuity" (the Post-COIE continuity, of course!) the idea that Alfred is an "old family retainer" who's been hanging around the Manor ever since Bruce's parents were alive.

(Although I believe at least one or two of the other Post-COIE writers have written things that stated or implied that Alfred only started working at the Manor after Bruce was a grown man, but in general that's no longer the "conventional wisdom" on the subject.)
