The original Vigilante, Greg Sanders (later changed to "Greg Saunders" decades later) was first featured in Action Comics #42 (November 1941).

His "origin" was covered in just a few panels of that introductory story.

Vigilante's run in Action Comics would last until issue #198 (November 1954).

And in addition to his feature in Action Comics, Vigilante was also a member of the Seven Soldiers of Victory during that group's fourteen issue run in Leading Comics between 1941 and 1945.
