Q: Just re-read Gotham Central and it got me wondering, what's the deal with the Spectre? -- @BatIssues
A: The Spectre was originally created in 1940 by Jerry Siegel and Bernard Baily, but it's worth noting that some sources -- including legendary editor Roy Thomas, who's about as big a fan of DC's Golden Age titles as you're likely to find -- give Siegel full credit for the whole concept, and that's the first interesting point. After all, Siegel is, as you may have heard, the co-creator of arguably the most enduring and significant character in comics history, who's known for his incredible physical strength: Slam Bradley.
Oh, and also Superman, I guess.
