Who was Warren Crichton (on "Batman")

Looking at the IMDb entry for the 1960s television programme Batman, I notice that a character called Warren Crichton appeared in 10 episodes.

I have no recollection of this character. Can anyone provide details?

**Warden ** Crichton.

As I recall, he was the warden of the local jail. I seem to recall his being easily duped.

D’oh! How did that happen?

Hmm … Doing a Google search for “Warren Crichton” and Batman, I come up with hits, including this one, which lists “David Lewis (Warren Crichton).”

So I guess I’m not the only one.
