Dan Dunn

Origin
Dan Dunn was the first fictional character to make his debut in an American comic magazine, making him the forerunner of many comic book heroes. Created by Norman Marsh, he first appeared in Detective Dan, Secret Operative No. 48, a 1933 Humor Publications magazine, which was canceled after one issue.

Later in 1933, Dan Dunn made his newspaper debut in the Dan Dunn comic strip for Publishers Syndicate. He eventually appeared in Big Little Books, which are probably the most readily available source of the character's adventures for modern readers. In 1936, Dan Dunn became the title character of a pulp magazine that lasted for two issues.
