Who's This? You tell me. The guy dressed as a blue bat on page 12 of Who's Who vol.II.
How you could have heard of him: There's a chance he appeared after his entry in Who's Who, but if so, I seemed to have missed it.
Example story: Detective Comics #260 (1958) "The Mystery of the Space Olympics"
I'd have to do a lot more research to find out. Maybe someone can reprint these stories some day - Kickstarter could help? - but I wouldn't be in any hurry. The bat motif just seems an ill fit for space cadet-type adventures.
Who's Next? Back to our regularly scheduled dissection of Who's Who vol.XXVI.
