Author byline excluding specific admin

Hi,

I am looking to include a byline on my blog for the various authors and used this code:
<p>By: <?php the_author(''); ?> </p>

It works exactly how I want, except that it shows me (admin) on the About (http://www.oic-books.com/blog/about/) and Archive (http://www.oic-books.com/blog/archive/) pages as the author.

I tried changing the code to
<p>By: <?php the_author('exclude_admin=1'); ?> </p>
but I still show up. (I also tried =0 and changing it to my username: OIC_Admin.)

Any help you can provide is appreciated.
Emily
