Created by Norman Marsh, Dan Dunn made his big splash in newspaper comics, but started out in comic books. Dunn started at the short-lived Humor Publications Co. in 1933 in a one-shot called Detective Dan, Secret Op. 48.
Humor Pub. folded after only 3 issues. Marsh took Dunn to Publishers Syndicate who transferred him from comics to newspapers.
On the whole Dan was pretty much a clone of Dick Tracy save that Dan sometimes went up against bad guys that wanted to take over the world . He often helped out a little orphan girl named Babs and her dog Wolf.
Like the Black Hood at Archie and Ka Zar at Timely he was one of the few comic book characters to appear in his own pulp magazine, which lasted only 2 issues.
A Dan Dunn radio series lasted for 78 episodes.
