Adding a hyperlink in an Element

Hello! I'd like to replace the Author Link with a Hyperlink on my Post Header. It's currently controlled by Elements:

<h1>
{{post_title}}
</h1>
[modified_date] | {{post_author}}

End result I'm looking for is:

All blog posts showing a name I choose and that name will be the same on all posts and linking to the about page. It is working that way now with a 301 redirect from the author page to about. I'm wondering if I can accomplish the same without a redirect.

<h1>
{{post_title}}
</h1>
[modified_date] | {{post_author}}

This was suggested on the FB forum:

<span><a href="url for about page">Authorname><a/></span>

But ended up messing with my Footer Element, and turning entire posts into a giant hyperlink.

I also tried:
<a href="url for about page">Authorname><a/>

Still broke things.

Thanks!
