I may be missing something, but I can't find a way to display the name of a page's author or publisher.

I need to include the following byline on the footer of each page:
"Page last updated by [Author] on $LastEdited"

What is the cleanest way to achieve this? Thank you!

class Page extends SiteTree{
	static $has_one = array(
		'Author' => 'Member',
	);
	function onBeforeWrite() {
		parent::onBeforeWrite();
		$this->AuthorID = Member::currentUserID();
	}
}

"Page last updated by $Author.Firstname $Author.Surname on $LastEdited"

Thanks Devlin.

I was hoping I might be able to use the preexisting versioning information somehow (since its available on the history tab for each page), but I may have to do it this way, since I can't find another working solution.

Well as you mentioned it. You could do this without any php modifications:

"Page last updated by $allVersions.First.Author.Surname on $LastEdited"

But I think the first solution is cleaner. (edit: -- since I like to truncate the versions table once in a while.)

Pretty sure you can just do $Author.Name to get any page author's name.
