Find which Contributor made a page?

I am trying to find basic data on a page that was created before I was working on this website. I was able to find the rough date that it was created (through Google cache), but I also want to know who created the page. Is there any way to find that out?

This is a guide about contributors and how each template lets you see them or not:

Style settings will let you hide or unhide an author depending on the template
